A kind of wireless network situ analysis system and methodTechnical field
The present invention relates to the network monitor technical field of wireless network, particularly relate to a kind of wireless network situ analysis system and method.
Background technology
Two words of active wireless network technical concerns are micropower and intelligent networking; The wireless network with such feature often has short distance, multi-hop, self-organizing, Mesh network, low-power, low rate, can the feature such as auto sleep.The complicated wireless network of this classes all and cable network be deployed with obvious difference: cable network pays close attention to connectivity and the topological structure of network, only need certain topological structure to be coupled together by the various network equipment during deployment, just complete most mapping out the work; Phase and in operation after deployment, only need to carry out unified management in machine room.
Complicated wireless network not only pays close attention to connectivity and topological structure, also pays close attention to site environment.Wireless network can the feature of auto sleep contribute to reducing network energy consumption very much, but has also broken the connectivity of communication node, and except being communicated with, also there is a kind of state outside not being communicated with: dormancy, such fixer network connectivity problem is also more complicated.The self-organizing of wireless network, the feature of Mesh network makes the topological structure of wireless network difference environmentally and is in different states, even cannot determine network topology structure sometime.Communication node the is broken away from constraint of power line of the feature of wireless network micropower, can adopt powered battery.So the installation site of communication node is very random, the communication node of same network all may be distributed in indoor or outdoors, on visual or not visible position.The feature of wireless network short distance makes communication comparatively large by the impact of on-the-spot complex environment, and in reality, electromagnetic pollution, radio interference all has and can produce considerable influence to wireless network.
Technically, even do not have a kind of current techique or system can diagnose or solve the various practical problems of wireless network: optimal design, performance bottleneck, energy consumption bottleneck is located, various transmission fault location: comprise operating lag, rate reduction, energy consumption uprises, packet loss increases, and forms information island etc.General method uses network analyzer, and spectrum analyzer, hand-held set etc. detect the various environmental parameters at wireless network scene, wireless data etc., then are aided with artificial analysis and diagnosis, finally draw final solution.
But common wireless network analysis system, as described in network analyzer, spectrum analyzer, hand-held set great majority are displays, control, and gather the autonomous device of one, cost is high, and volume is large, is not suitable for onsite application.Common wireless network analysis system is often embedded system, and the initial data about environment a large amount of to scene cannot carry out knowledge processing, is difficult to carry out Remote Collaborative Diagnosis, therefore requires that user has higher professional knowledge.These above-mentioned problems make the inefficiency of on-site land survey and cost is high, make the work of wireless network field assay become the work of a time and effort consuming and high cost.
