An Opportunistic Routing for Mobile Wireless Sensor Networks Based on RSSI
本文针对移动无线传感网提出一种结合节点移动向量和接收信号强度指示值RSSI(Received Signal Strength Indicator)信息的机会主义路由OR-RSSI
利用Sink节点Beacon报文的RSSI信息建立并更新机会概率值
使用报文广播后所能到达的具有最大机会概率值的最佳节点进行存储转发
完成移动无线传感网信息收集.OR-RSSI是一种良好的后择路由
不以既存路径为基础
不需额外设备支持
具有报文成功传输率高、网络有效吞吐量大以及能耗低等优点.
Abstract
In Mobile Wireless Sensor Networks (MWSN) with a sparse node population
an end-to-end path may be broken frequently or may not exist at any time due to nodes’ mobility
which makes it impossible to apply the existing shortest-path routing protocols based on static topology for MWSN.An RSSI-based opportunistic routing protocol for MWSN
called OR-RSSI
is proposed in this paper.In OR-RSSI
Opportunistic Probability(OP)based on the RSSI of the Sink’s Beacon packets and Mobility Vector (MV) is established and the best node with the highest OP is chosen to store and relay packets at each hop after packets are broadcasted.Simulation results show that OR-RSSI performs better on successful delivery ratio
goodput and energy overhead as compared with traditional TinyAODV.
