The Research Of Health Evaluation System Based On Cognition Network Behavioral Model

The cognitive network is a new type network which is self-cognitive, self-adapt, self-autonomy and so on. It can works methodical under the control of KP. So how to evaluate the cognitive network and to design a complete evaluation system is very important both in the theory and reality.The experience on research of "The Research of the key technology of QoS base on cognitive network behavior model "were summed-up and abstracted to enrich this paper. First solve the key technology of cognitive network which is network behavior model, then focus on the evaluation system of the cognitive network. What's the impotent is make sure the evaluation indicator, because it will influence the rationality and exactly of the evaluation. At present the evaluation indicator just focus on the some parts like the delay of one point. But to cognitive network the evaluation indicator must be over spaces and comprehensive which is important to realice the cognitive network.In this paper, we first introduce the character and key technology of cognitive network, then describe the impotence of the health evaluation system. secondly, analyze the short of existing evaluation, and apply the health evaluation model which is base on the cognitive network:base on the character of service and pick up the proper indicator to calculate the health of the service. Then calculate the health of the links and routers in the same way. Finally, calculate the health of all cognitive regions. Through the this complete health evaluation system to enhance the self-adapt, self-autonomy, and make sure the QoS of different client.This system including definition, computational method and formula.Finally, through carried on the simulation modeling of the cognitive network to prove the evaluation system's feasibility which is proposed by this article.
