摘要
文章针对定向扩散(DD)路由协议在能效方面的不足,提出了一种改进方案(AIDD)。该方案通过预测跳数控制数据的传输距离,同时考虑节点的剩余能量和传输能耗因素,通过决策函数选择转发节点。仿真结果表明,改进方案实现了网络的全局能量平衡,避免了因丢包而重传引起的能量消耗,提高了转发率,从而延长了网络的生命周期。
In order to cut down the energy cost, this paper proposes all improved routing protocol which is named AIDD based on the directed diffusion（DD）. AIDD controls the distance of data trans- mission by the predicted hop. Besides, it takes the remainder energy of the node and transmission con- sumption into account, and uses the decision function to choose the next node. Simulation results in- dicate that AIDD achieves energy balance of WSN and avoids energy consumption caused by the re- transmission of data packet, so it prolongs the lifecycle of WSN.
