【摘要】 无线传感器网络的关键问题之一是减少能量的消耗、提高节点的存活率。针对LEACH协议能量消耗快、网络生存时间短的缺点,提出一种基于LEACH的改进协议(ILEACH)。对ILEACH协议进行仿真实验,仿真结果表明,与LEACH协议相比,ILEACH协议能有效平衡节点间开销,提高能量有效性,降低网络整体能耗,延迟节点的死亡时间,从而明显提高了网络的生存周期。更多还原

【Abstract】 It is one of key issues for WSN that reduce energy consumption and improve the survival rate of nodes.In allusion to the disadvantages of fast energy consumption and short network lifetime for LEACH protocol,Low Energy Adaptive Clustering Hierarchy (ILEACH) protocol is proposed based on improving LEACH protocol.A simulation experiment is carried out and the result indicates that ILEACH is very effective in reducing the total costs between nodes,improving energy efficacy,lowering energy consumption of the network,and enhancing nodes ’ lifetime,which significantly improves the network lifetime.更多还原
