摘要：

 基于按需距离向量路由协议，提出了一种针对无线传感器网络的自适应拥塞控制路由协议，所提出的协议根据时间序列预报算法获得未来时刻的网络流量预报值，并由此判断节点的拥塞程度以便预先采取分流措施，实现对路由的自适应控制. NS2仿真实验表明，该协议有效地提高了网络性能，特别是对网络拥塞和流量均衡的改善较大.

Abstract:

Based on Ad Hoc on-demand distance vector (AODV), a routing protocol of WSN is proposed, called adaptive congestion control routing protocol based on traffic prediction (AccRPbTP). Using a time series prediction algorithm, AccRPbTP obtains the prediction value of future networks traffic, and estimates congestion level. Thus, adaptive control to route is achieved by taking diverted route in advance. NS2 experiment results show that AccRPbTP effectively improve the networks performances, especially in network congestion and load balance.

Key words: wireless sensor networks, time series, traffic prediction, routing, congestion, Ad Hoc on-demend distance vector (AODV)
