一种基于AODV的能量感知路由协议

An Energy-aware Routing Protocol Based on AODV

在传统路由协议AODV的基础上,提出一种能量感知路由算法EA-AODV。该算法通过MAC层协议完成对链路层的功率控制,在每一个发送的数据包里携带功率信息,使节点选用和其自身能量成反比的最小代价链路进行数据传输,以达到节能的目的。仿真表明,该算法有效降低了网络能耗,延长了网络生存时间,提高了链路稳定性和网络性能。

A new energy-aware routing arithmetic called EA-AODV was proposed in this paper. The algorithm completes the link layer power control through the MAC layer protocol and it could carry on the power information by each transmission packet, so the node selects the minimum cost path which is in- verse proportion with its own energy for data transmission to achieve the purpose of energy saving. Simulations show that the new mechanism can reduce the network energy consumption and prolong the network lifetime effectively so it improves the link stability and the network performance.
