Study of AFN Disposition and Congestion Control Tactics of WSN Based on QoS

In order to solve the AFN disposition and congestion control tactics problems in wireless sensor networks (WSN), based on the self features of WSN, and by using the contrast research of QoS between tradition networks and WSN, this paper brings forward the scheme that AFN was laid at source where have maximum packet flows. So, not only reliability of networks was enhanced, but also grouping delay and transmission costs were reduced. In the process of networks congestion, this paper puts forward the self-improvement congestion control tactics in order to guarantee quality of real time streams and precision of key flows. And by researching and analyzing the algorithm, multi-path adaptive were established in order to adjust resource provision and increase grouping precision.
