摘要: 针对大部分无线传感器网络路由协议只能实现局部能量均衡的问题,提出一种改进的能量均衡路由算法,把传感器网络构建成按最小跳数分层的网络,利用节点直接传输和逐跳转发相结合的混合传输策略,在多跳传输时,使用改进的基于多路径路由的最大能量路径算法。仿真结果表明,该算法能有效延长网络的生存时间。

Abstract: Most current protocols just achieve the local energy balance of Wireless Sensor Networks(WSNs). To solve this problem, a modified energy balance routing algorithm is proposed. It constructs a layered network by minimum hop count, and uses a mixed transmission mode resulting from hop-by-hop forwarding combined with direct forwarding. In hop-by-hop transmission, it uses the modified multi-path routing scheme based on maximum energy path. Simulation results show the lifetime of the networks is prolonged efficiently.

Key words: Wireless Sensor Networks(WSNs), energy balance, longevity of networks, multi-path routing
