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.
In this paper, we study the energy consumption of wireless sensor networks (WSN) cooperative routing algorithm in general topology and its influencing factors.On the basis of the Amir collaborative link cost model, it is theoretically proved that the cooperation routing will inevitably bring about energy saving.At the same time, From the practical point of view, the energy consumption of the node transceiver circuit is studied. The simulation results show that under the free space model, the energy saving value is inversely proportional to the power consumption of the transceiver circuit, and its limit is that the energy consumption of the transceiver circuit is The energy saving value at zero hour; the energy saving value of the cooperation route also has a positive correlation with the number of nodes participating in the collaboration and the total number of nodes in the network.
