一种低功耗无线传感器网络多径路由优化协议

针对无线传感器网络多媒体传输应用中,单通道路由方案无法获得理想效果的问题,提出了一种低功耗多径路由优化协议(EEOR)。在这个协议中,通过邻居之间的消息交互建立最大化多路径,并引入了多路径选择机制来剔除无意义的路径。在多路径建立过程中,首先考虑降低端到端延迟,其次维护网络的能量平衡。仿真结果显示,提出的方案与其他两种路由协议相比网络生命更长、可靠性更高、端到端的延迟和控制开销更低。

An Energy-Efficient Optimal Multipath Routing Protocol for Wireless Sensor Networks

We propose an energy-efficient optimal multipath routing protocol(EEOR) to improve the shortcomings of single path schemes that can not obtain the ideal effect in some multimedia transmission applications.In this protocol,maximum multipaths are found by message exchanges between the neighbors and a multipath selection mechanism is introduced to eliminate the meaningless paths.In the process of multipath finding,reducing end-to-end delay is firstly considered and then keeping the energy balance of the network.The simulation results reveal that our scheme has longer network lifetime,higher reliability,lower end-to-end delay and control overhead than other two routing protocols.
