基于位置感知和代理的WSN多径路由方案

针对无线传感器网络(WSN)中多径路由的可靠性和能量效率问题,提出了一种基于代理和位置感知的多径路由发现方案(LABMR).事件节点根据位置信息,动态寻找其到Sink节点之间的特殊中间节点,来构建多径路由.利用移动代理来收集多径路由的局部拓扑结构信息,Sink节点根据代理收集的路由参数来计算路径权值,以此选择最优不相交路径.同时,对于信息的重要性差异,Sink节点选择单条或多条路径来传输数据,在保证传输可靠性的同时减少能耗.与现有的基于代理的多径路由(ABMR)方法相比,LABMP在数据包投递率、能量消耗、额外开销和延迟方面具有更好的性能.

Location aware and Agent based multipath routing scheme in WSN

To solve the problem of the reliability and energy efficiency of multipath routing in WSN, a multipath routing scheme based on location aware and Agent (LABMR) has been proposed. The event node searches for special intermediate nodes between sink node and event node according to location information, in order to build multipath routing. LABMR uses the mobile agents to collect the partial topology information of multipath routing, which will be used by sink node to compute the path weight, so as to find out the optimal disjoint paths. Meanwhile, sink node selects a single path or multiple paths to transmit information according to its importance, to ensure transmission reliability as well as reduce energy consumption. Compared with ABMR scheme, LABMP has better performance in packet delivery ratio, energy consumption, overhead and latency.
