摘　　要：针对无线传感器网络能量受限的特征,提出了一种基于功率控制的AODV改进协议。通过在路由请求消息中增加当前节点和下一跳节点的位置信息,通过计算节点所需的最优发射功率来选择微处理器中的合适的功率级别来传送报文,使发送每个报文所耗费的能量最小,达到节省能量的目的。仿真实验结果表明,新协议有效提高了节点的能量利用率,降低了网络的路由开销和总能耗。Aimed at the character of energy limitation of wireless sensor networks,to solve this problem,an improved AODV protocol based on power control is proposed.The position of current node and next hope node is added to the route requesting message,the right transmission power level in the microchip is selected to send the packet through calculating the optimum transmission power,energy mini-mization is used in packet transmitted.The simulation shows that the improved AODV protocol effectively improve energy utilization of the node,decrease the routing overhead and total energy consumption of the network.
