摘要
针对现有的井下无线传感器网络广播算法能耗较高的问题,提出了一种改进的无线传感器网络前向广播算法。该算法中,转发节点可根据自身位置,选择优先节点转发信息,大大减少了无线传感器网络中需要转发的冗余信息量,从而降低了网络能耗。仿真结果表明,该算法在网络节点密度达到一定值时,满足网络接收率要求,且能够限制转发的信息总量,有效降低了无线传感器网络能耗。
For problem of high energy consumption of existing broadcasting algorithm for underground wireless sensor network,an improved forward broadcasting algorithm of wireless sensor network was proposed.In the algorithm,forwarding nodes select prioritized node to forward information according to their own positions,so as to decrease redundant forwarding information and reduce energy consumption of the network.The simulation results show that when network node density achieve certain value,the algorithm can satisfy network receiving rate requirement,and limit total forwarding information,so as to reduce energy consumption of wireless sensor network effectively.
