A Novel Cooperative Wake-up Routing Algorithm for Wake-up Mechanism in Heterogeneous Sensor Networks

基于定向扩散算法,本文提出一种适用于唤醒机制的异构传感器网络节点协同唤醒路由算法(CWR,Cooperative Wake-up Ruting),就近选取低能耗节点代替高能耗节点进行多级扩散,增加路由替换和路由修补两个步骤建立低能耗节点到相应高能耗节点的路由信息,为异构传感器网络中唤醒实现提供必要的网络拓扑基础.仿真实验表明本文算法在支持唤醒机制实现过程中的节能特性.

Based on directional diffusion algorithm, this paper proposes a novel cooperative wake-up routing algorithm （CWR algorithm） for wake-up mechanism in heterogeneous sensor networks. We substitute a high-cost node with the nearest lowcost node, which launches multi-hop diffusion. In particular, we add two steps： routing displacement and routing repair to establish network topology between low-cost nodes and their corresponding high-cost nodes, thus provide a necessary network topology foundation for wake-up mechanism. Simulation results demonstrate that our CWR algorithm is energy-efficient during wake-up process.
