摘要: 为均衡及降低无线传感器网络(WSN)的路由能耗并最终延长网络的寿命,提出一种具备网络编码感知且能耗敏感的WSN路由策略。该策略通过对WSN环境中存在的网络寿命限制、数据流限制、广播流量限制3个重要因素的分析,对能耗最优路由进行建模,最后归结为对最优化问题的求解获得最佳路径。仿真实验表明该路由策略能够较好地均衡节点的能耗,从整体上显著延长WSN的生存期。

Abstract: For the purpose of balancing and decreasing the routing energy consumption of Wireless Sensor Network (WSN), this paper put forward a network coding based routing policy with friendly energy consumption feature. Three restricts on network lifetime, data flow and multicasting flow in WSN were analyzed in detail. Simulation results show this policy can balance energy consumption better than other policies, and can notably extend the lifecycle of WSN.
