Abstract

This paper presents an Mobile Agent based Coding Aware Routing (MA-CAMR) for wireless sensor network, which exploits mobile agent to discovery the routing and coding opportunities, reducing complexity of node design. Besides, the general network coding condition of two cross flows is proposed for coding opportunity discovery. In addition, a novel routing metric, Coding and Energy Aware Routing Metric (CEARM) is proposed, which considers the coding gain, the load and energy of node. MA-CAMR exploits multipath routing and CEARM to balance the network load and energy consumption. Simulation results demonstrate that MA-CAMR could balance network load and energy consumption, reduce energy consumption, and prolong network lifetime.
