Research on Adaptive Congestion and Energy Routing Protocol in Wireless Sensor Networks

摘要: 本文从无线传感器网络基于路由协议的拥塞控制技术入手，改进AODV路由协议，提出了拥塞和能量自适应的无线传感器网络路由协议WSNCA-AODV。通过节点缓存利用率、拥塞因子确定节点拥塞状态；通过节点拥塞状态、剩余能量、离Sink节点的距离来确定节点的转发满意度；以节点转发满意度为依据，创建主路由和辅助路由，在拥塞产生时，将数据流按比例分流在主路由和辅助路由上，实现WSN的拥塞自适应和能量自适应功能。

Abstract:  This article starts from the wireless sensor network routing protocol based on congestion control techniques, improves AODV routing protocol and proposes adaptive congestion and energy routing protocol for wireless sensor networks WSNCA-AODV. By node cache utilization, node congestion state can be determined by congestion factor. Through node congestion state, the remaining energy and distance from Sink node, node satisfaction forwarding can be determined. According to node satisfaction forwarding, the main routes and auxiliary routes can be created. When the WSN is congesting, it can proportionally split the data stream on the main routes and auxiliary routes, and achieve adaptive congestion and energy function in WSN.
