针对不可靠的Ad Hoc网络,提出一种基于可靠链路层的节能路由协议。该路由协议在寻路过程中,综合考虑了最大化网络生命期和最小化每个包的能量花费。该协议考虑了链路的可靠性,采用功率控制技术,能够恰当处理包丢失问题。通过大量仿真试验,并与已有的路由协议进行对比,表明该协议在保证网络性能的前提下能有效节省能量、延长网络生命期。
This paper presents an Reliable Energy-Aware Routing Protocol(REARP) which is based on reliable link layer model. The REARP tries to maximize the lifetime of the whole network, and at the same time, minimize the total energy cost for each packet. Moreover, the REARP appropriately handles packet losses by systematically integrating the reliability and power control techniques. Extensive simulations are conducted to evaluate the performance of the new routing algorithms compared to a number of existing routing algorithms.
