摘要
LEACH协议是一种低能耗自适应的无线传感器网络分簇协议,基于簇间多跳的改进型协议进一步提高了网络寿命。然而,LEACH协议不是为多跳传输设计的,直接引入簇间多跳机制会带来严重的数据冲突问题。针对该问题,本文提出了基于双簇首的同簇异频分层多跳路由协议LEACH-DC。NS2仿真结果表明,所提出的协议可以很好地解决簇间多跳带来的数据冲突问题,延长网络寿命。
The LEACH protocol is a low-energy adaptive clustering protocol for wireless sensor networks.The improved protocols based on multi-hop between clusters further improve the network life.However,the LEACH protocol is not designed for multi-hop transmission.Direct introduction of the inter-cluster multi-hop mechanism will bring about serious data collision problems.To solve this problem,this paper proposes LEACH-DC,a hierarchical multi-hop routing protocol based on double different frequency cluster heads.The NS2 simulation results show that the proposed protocol can solve the data collision problem caused by multi-hop between clusters well and prolong the network life.
