摘要
为了解决LEACH协议无法控制簇首位置和簇首选择方式而导致能量消耗太大的缺点,提出了以非均匀分簇和双簇头路由作为改进方法的一种基于能耗均衡的LEACH-DC协议。对改进的LEACH-DC协议使用NS2进行了仿真实验,仿真实验结果表明,改进后的路由协议在网络总能耗以及数据传送量等方面均得到明显改进,从而均衡了无线传感器的网络能耗,延长了网络生命周期。
In order to solve the inability to control duster head position and the way to choose duster head lead to too much energy consumption in LEACH protocols, the non-uniform cluster and dual cluster routing as improvement methods based on energy consumption balanced LEACH-IX2 protocol is proposed. The improved LEACH-DC protocols use the NS2 simulation experi- ment, simulation experimental results show that the improved routing protocols in total energy consumption and network data transfer quantity etc. get the obvious improvement, and the wireless sensor network energy consumption is balanced and the net- work life cycle is prolong.
