The electronic device receives feedback information sent by a plurality of neighboring devices, wherein the feedback information includes network quality information of the neighboring devices and also includes identification information of the neighboring devices, so that the electronic device can determine which neighboring devices have the target data and which neighboring devices do not have the target data.
The NAN network may include a plurality of NAN devices, and network qualities of different NAN devices may be different, where the network qualities may include a data transmission speed of the NAN devices or security of data transmission, and are not limited herein.
S203, the electronic device selects at least one adjacent device from the plurality of adjacent devices according to the feedback information, and acquires the target data from the at least one adjacent device.
The electronic equipment selects at least one adjacent device according to the feedback information sent by the adjacent devices, acquires the target data from the adjacent devices, and distributes the split target data to each adjacent device in the at least one adjacent device, so that the target data can be acquired from the at least one adjacent device in a parallel mode, and the data processing efficiency is improved.
It can be seen that, in this embodiment of the application, an electronic device first sends a target data obtaining request to a plurality of neighboring devices, where the plurality of neighboring devices carry the target data, then receives feedback information sent by the plurality of neighboring devices, where the feedback information includes network quality information of the plurality of neighboring devices, and finally selects at least one of the plurality of neighboring devices according to the feedback information to obtain the target data from the at least one neighboring device. The electronic equipment can send the target data acquisition request to the plurality of adjacent equipment carrying the target data in the adjacent sensing network, and selects at least one adjacent equipment with good network quality according to the feedback information sent by the plurality of adjacent equipment, so that the target data can be acquired from the at least one adjacent equipment at the same time, and the efficiency and the stability of acquiring the target data are improved.
In one possible example, the network quality information includes a security protocol employed by the plurality of neighboring devices during data transmission; the selecting at least one neighboring device from the plurality of neighboring devices according to the feedback information and acquiring the target data from the at least one neighboring device includes: splitting the target data according to the security requirement of the target data to obtain multiple copies of data, wherein the multiple copies of data correspond to different security levels; selecting at least one adjacent device of the plurality of adjacent devices, the safety of which meets a preset condition, according to a safety protocol adopted by the plurality of adjacent devices; matching the multiple data with the at least one adjacent device, wherein the data with high security level corresponds to the adjacent device with high security; and acquiring the multiple copies of data from the at least one adjacent device to obtain the target data.
The network quality information comprises a security protocol adopted by a plurality of adjacent devices in a data transmission process, the security protocol can be an encryption mode for transmitting data, such as an encryption method, the data encryption methods adopted by different adjacent devices in the data transmission process are possibly different, the security protocol can also be an encryption password, a default encryption password is arranged between the electronic device and the adjacent devices, the data can be checked only after the encryption password is input, the security of the adjacent devices in the data transmission process can be determined according to the security protocol of the adjacent devices, and therefore at least one adjacent device, the security of which meets preset conditions, in the plurality of adjacent devices is selected. For example, 3 neighboring devices are selected, and the security of the neighboring device 1 is greater than that of the neighboring device 2, and the security of the neighboring device 2 is greater than that of the neighboring device 3.
The method comprises the steps of splitting target data to obtain multiple data according to the security requirement of the target data, wherein each data corresponds to different security levels. For example, the target data is file data, a part of the file data may relate to confidential content, the file data is divided into file data a, file data B and file data C corresponding to a high security level, and the file data a, the file data B and the file data C are sequentially arranged from high to low in the security level. And matching the split target data with at least one adjacent device, wherein the file data A corresponds to the adjacent device 1, the file data B corresponds to the adjacent device 2, and the file data C corresponds to the adjacent device 3.
As can be seen, in this example, the target data is split into multiple pieces of data, each piece of data corresponds to a different security level, at least one neighboring device of the multiple neighboring devices, whose security meets a preset condition, is simultaneously selected, and the neighboring device with high security corresponds to the data with high security level, so that the multiple pieces of data can be simultaneously obtained from the at least one neighboring device to obtain the target data, and the security during data transmission is ensured.
In one possible example, the network quality information includes data transmission speeds of the plurality of neighboring devices; the selecting at least one neighboring device from the plurality of neighboring devices according to the feedback information and acquiring the target data from the at least one neighboring device includes: selecting at least one adjacent device of the plurality of adjacent devices, wherein the data transmission speed of the at least one adjacent device is greater than a preset speed; splitting the target data into a plurality of data sets according to the data transmission speed of the at least one adjacent device, wherein the data sets are different in data quantity; and acquiring the multiple copies of data from the at least one adjacent device to obtain the target data.
The electronic device selects at least one neighboring device from the plurality of neighboring devices, the data transmission speed of which is greater than a preset speed, and splits the target data into a plurality of data according to the data transmission speed of the at least one neighboring device, wherein each data corresponds to different data size.
As can be seen, in this example, at least one neighboring device with a data transmission speed greater than a preset speed is selected from the multiple neighboring devices, and the target data is split into multiple pieces of data, where the data size of each piece of data is different, so that the data with a large data size can correspond to the neighboring device with a high transmission speed, and thus, the target data can be acquired from the at least one neighboring device in parallel, which is beneficial to improving the data acquisition efficiency.
In one possible example, the splitting the target data into multiple pieces of data according to the data transmission speed of the at least one neighboring device includes: determining a speed proportional relationship of data transmission speed of each of the at least one neighboring device; splitting the target data according to the speed proportional relation to obtain multiple data sets, wherein the data quantity proportional relation of each data set in the multiple data sets is matched with the speed proportional relation, and each data set corresponds to one adjacent device; and informing the electronic equipment to acquire corresponding data from each of the at least one adjacent equipment to obtain the target data.
The electronic device may determine a speed proportional relationship of data transmission speeds of each neighboring device in the at least one neighboring device, so that the target data may be split into multiple data according to the speed proportional relationship, that is, a proportional relationship of data size of each data in the multiple data is equal to the speed proportional relationship, and each data corresponds to one neighboring device. For example, the speed ratio of the neighboring device 1, the neighboring device 2, and the neighboring device 3 is 3:1:5, the data size of the target data is 900 megabits, the target data is split into 3 parts, which are 300 megabits, 100 megabits, and 500 megabits in sequence, the neighboring device 1 transmits 300 megabits of data, the neighboring device 2 transmits 100 megabits of data, and the neighboring device 3 transmits 500 megabits of data, and thus, the ratio of each part of data matches the speed ratio, and the electronic device can acquire the target data in a short time.
It can be seen that, in this example, the data transmission speed of each neighboring device in at least one neighboring device is determined, the target data is split according to the speed proportional relationship to obtain multiple pieces of data, each piece of data corresponds to one neighboring device, and the data size is allocated according to the data transmission speed of each neighboring device, which is beneficial to effectively utilizing the data transmission speed of the neighboring devices, shortening the total time for acquiring the target data, and achieving that each piece of data is acquired in multiple neighboring devices at the same time.
In one possible example, the target data is video data; the acquiring the target data from the at least one neighboring device comprises: splitting the video data into a plurality of data shares, wherein each data share corresponds to the playing time sequence of the video; acquiring a data transmission speed of each of the at least one neighboring device; matching the plurality of data with each of the at least one neighboring device, wherein the playing time sequence of the data matched by the neighboring device with a first data transmission speed is earlier than the playing time sequence of the data matched by the neighboring device with a second data transmission speed in the matching relation, and the first data transmission speed is higher than the second data transmission speed; and acquiring data corresponding to each adjacent device from the at least one adjacent device to obtain the target data.
When the target data is video data, because the video data has a time sequence during playing, after the video data is split into a plurality of data, the playing time sequence of the data corresponding to each data is determined; for example, one video data with a playing time of 9 seconds, the split data 1 corresponds to 1-3 seconds of video data, the data 2 corresponds to 4-6 seconds of video data, and the data 3 corresponds to 7-9 seconds of video data.
After at least one adjacent device is selected from the multiple adjacent devices for data transmission, determining the data transmission speed of each adjacent device, and matching the split multiple data with each adjacent device, wherein the playing time sequence of the data matched by the adjacent device with the first data transmission speed in the matching relation is earlier than that of the data matched by the adjacent device with the second data transmission speed, and the first data transmission speed is higher than that of the data with the second data transmission speed, namely the adjacent device with the high transmission speed corresponds to the adjacent device with the earlier playing time sequence. For example, the data transmission speed is from high to low for the neighboring device 1, the neighboring device 2, and the neighboring device 3, so that the data 1 can be transmitted by the neighboring device 1, the data 2 can be transmitted by the neighboring device 2, and the data 3 can be transmitted by the neighboring device 3, so that the electronic device can receive the data 1, the data 2, and the data 3 in sequence.
As can be seen, in this example, when it is detected that the target data is video data, the video data may be split into multiple pieces of data, each piece of data corresponds to a different play time sequence, and data with a previous play time sequence corresponds to a neighboring device with a fast data transmission speed, which is beneficial for the electronic device to sequentially obtain the multiple pieces of data according to the play time sequence so as to obtain the target data, and simultaneously, the electronic device may obtain the video data while playing the video data.
In one possible example, the sending target data acquisition requests to a plurality of nearby devices includes: acquiring a connection record between the adjacent equipment and the electronic equipment in the adjacent perception network; determining an affinity value between the proximity device and the electronic device from the connection record; and sending the target data acquisition request to a plurality of adjacent devices of which the intimacy values are greater than a preset threshold value.
When the electronic device sends the target data acquisition request to the plurality of neighboring devices in the plurality of NANs, the electronic device may acquire connection records between the plurality of neighboring devices in the NANs and the electronic device, determine affinity values between the neighboring devices and the electronic device according to the connection records, the connection records include records of whether the neighboring devices are connected with the electronic device and perform data transmission, and connection times, and the electronic device may select the plurality of neighboring devices whose affinity values are greater than a preset threshold value and send the target data acquisition request to the plurality of neighboring devices.
As can be seen, in this example, the electronic device may obtain affinity values between the plurality of neighboring devices in the NAN and select the plurality of neighboring devices having affinity values greater than a preset threshold, so that the target data obtaining request may be sent to the plurality of neighboring devices, and since the affinity values between the plurality of neighboring devices and the electronic device are higher, the plurality of neighboring devices are reliable and secure neighboring devices, which is beneficial to improving the security and reliability of the output transmission process.
In one possible example, the receiving feedback information sent from the plurality of neighboring devices includes: determining distances and data transmission speeds between the electronic device and the plurality of neighboring devices; and confirming to receive feedback information sent by the plurality of adjacent devices when the adjacent devices with the distance within the preset range and the data transmission speed higher than the preset speed are detected.
The NAN network comprises a plurality of adjacent devices, the electronic device sends the target data acquisition requests to the adjacent devices in a broadcasting mode, the electronic device can acquire the distance between the electronic device and the adjacent devices and the data transmission speed, and when the electronic device detects that the distance between the adjacent devices and the electronic device is within a preset range and the output transmission speed is higher than the preset speed, the electronic device receives the feedback information sent by the adjacent devices, so that the adjacent devices sending the feedback information are screened, and the data transmission efficiency is improved.
As can be seen, in this example, the distance between the neighboring device that sends the feedback information and the electronic device is within the preset range, and the data transmission speed between the electronic device and the neighboring device is greater than the preset speed, so that the stability of the communication connection between the electronic device and the neighboring device can be ensured, which is beneficial to improving the reliability of data transmission in the data transmission process.
