一种两段式传感器网络路由协议

Two segment routing protocol for wireless sensor network

本文提出了一个两段式路由协议TSR,解决了目标追踪系统中主动路由协议效率低下的问题。在目标出现后首先建立一条主路由,然后随着目标的移动按需延长。与主动路由相比,实现了按需路由,节省了路由维护开销。与按需路由(DSR、AODV等)相比,减少了路由发现次数,降低了路由发现延迟对系统实时性的影响。仿真和实验表明TSR协议可大幅降低系统的路由开销,适合基于无线传感器网络的目标检测、追踪系统的应用。

This paper presents a two segment routing （TSR） protocol specially tailored for sensor network based object tracking systems. The first segment is established as soon as the target enters into the network, and then it is prolonged along with the track by which the target moves in the network. TSR is an on-demand protocol in the sense that there is no need to maintain the routing table when there is no target in the network. In contrast to other on-demand protocols such as AODV and DSR, the energy cost and delay of routing discovery are greatly reduced by routing extension. Simulation and field experiment indicate that TSR can greatly reduce the cost of routing service and is feasible for target detection and tracking network.
