针对无线传感器网络能量多路径路由算法存在的缺陷及其原因,提出一种基于动态优先级的能量多路径路由算法。该路由算法以节点距汇聚节点的路径跳数值替代路径能耗代价确定其优先级,并在数据传输过程中根据节点的能量消耗不断调整优先级,降低了算法的复杂度,避免了周期性路由维护所带来的时间与能量损失。仿真结果表明,该算法能有效降低和平衡各节点的能耗,延长整个网络的生存周期。
Abstract：Aiming at the defects and their causes of energy multipath routing algorithm in wireless sensor networks,the author proposed an energy multipath routing algorithm based on dynamic priority. The routing algorithm determined the priority of one node by replacing the path energy consumption cost with the hop count value between the node and the sink node,and constantly adjusted the priority of nodes in the data transmission process according to energy consumption of nodes,thus it reduced the complexity of the algorithm,and avoided time and energy loss brought by periodic routing maintenance. The simulation results showed that the algorithm could effectively reduce and balance the energy consumption of each node,and prolonged the lifetime of the whole network.
