一种新的应用于路由算法设计的分层模型——抽象分层模型被提出,该模型将节点分为两层:Level 1(Clus-ter-head层)和Level 0(Member层),切断了分簇模型中簇首与成员的对应关系,移动节点不再寻找簇首,而可以直接向Level 1节点发送信息,进而转送给基站。NS2下的仿真结果表明,在移动环境下新算法能够有效均衡能量消耗,高效传输数据,实现对移动性的支持。
This paper proposes a novel routing protocol based on abstracted hierarchy.It divides the nodes into two levels: Level 1(Cluster-head level) or Level 0(Member level),which breaks the ties between cluster-head and members.The mobile nodes can transfer data to the nodes in Level1 directly,then the data is transmitted to the base station.We have evaluated our proposed protocol under NS2 and the results show that it can effectively balance the energy consumption and significantly improve data rate,compared to LEACH under mobile scenarios.
