| 摘 要： | 针对无线传感器网络中节点能量受限的特征,深入分析了经典的LEACH路由协议;针对其在能耗和适用规模方面存在的不足,提出了一种新型自定义的跨区多跳路由算法((LEACH-CS)。新算法引入了“区域”的概念,即某区域选举簇头失败时产生补充簇头,建立簇间路由时以跨区距离的约束来自定义合适的多跳路由方案。实验表明,与现有LEACH协议相比,新的协议明显提高了网络的生存时间,平衡了网络的节点能耗,均匀了死亡节点的分布,也扩大了协议适用的网络规模。

| Abstract: | This paper, based on the existing LEACH routing algorithm, proposed a novel customizable zoncspanned multi-hop routing algorithm(LEACH-CS) for large-scale, energy limited wireless sensor networks. At first, we introduced the concept of "zone". On this basis,an additional cluster-head may be elected on demand during cluster-head selection process. The purpose is to optimize multi-hop routing with the constraint of multi-zone distance threshold. Our simulation experiment demonstrated that, compared with the existing LEACH protocol, the LEACH-CS could reduce the energy consumption of the cluster-heads significantly and extend the lifccycle of largcscale networks due to more uniformly distributed dead nodes. |
