CA-Based Energy-Efficient Routing Protocol for WSN

针对无线传感器网络(WSN)路由协议设计需首要解决的节能问题,提出一种将元胞自动机(CA)用于无线传感器网络的高效节能机制。该机制在路由层设置元胞处理模块,通过路由报文捎带CA信息网络节点自组织形成以sink节点为中心的多级元胞自动机区域,决策节点根据通信过程中携带的元胞信息切换传感节点的工作状态以实现节能。仿真结果验证了该机制能降低网络整体能量消耗,提高能量利用率,延长整个网络生存周期。

In this paper a cellular automata（CA）-based energy efficient routing protocol for wireless sensor network（WSN） is proposed to reduce the energy consumption of the wireless sensor nodes in the WSN. The wireless sensor nodes are self-organized to a multi-level CA area around the sink node. According to the CA message the sink node determines the state change of other wireless sensor nodes to realize the energy conservation. Simulation results demonstrate that the proposed routing protocol can reduce the network energy consumption, improve the energy utilization rate, and prolong the network life span.
