摘要
研究了一般拓扑意义下的无线传感器网络协作路由算法的能耗情况及其影响因素.在Amir协作链路费用模型的基础上,从理论上证明了协作路由传递一定会带来能量节省.同时,从实践的角度研究了节点收发电路能耗对路由算法节能效果的影响.仿真结果表明:在自由空间模型下,能量节省值与收发电路能耗成反比,其极限值为收发电路能耗值为零时的能量节省值;协作路由的能量节省值还与参与协作的节点数量、网络中的节点总数呈正相关的关系.
The energy consumption and affecting factors of cooperative routing in common wireless sensor networks topology were studied. On the basis Of the Amir link cost model, it was proved theoretically that cooperative routing was more energy effective than non-cooperative routing. The effect of send-receive circuit on energy consumption was also studied. It is concluded that with the increase of energy consumption by send-receive circuit, the energy saving percentage drops down, and if there is no energy consumption in send-receive circuit, the energy saving will reach the maximum value. Besides, there is a positive relationship between the energy saving value and the cooperative node number nodes and the total number of nodes in networks.
