摘要

聚类技术是大规模无线传感器网络的一种关键路由方法,极大地延长了网络的生存期和可扩展性。该技术的基本协议——低能量自适应聚类层次(LEACH)被证明是一种能够提供良好的能量效率,从而延长网络生存期的解决方案。随着网络规模的扩大,网络的能源效率不断下降,LEACH的改进变得越来越重要,以支持大规模无线传感器网络的可扩展性。提出了一种新的动态多跳聚类协议。它利用移动无线传感器网络的移动性和多跳通信来延长其生命周期。提出的动态多跳LEACH (DMH-LEACH)协议将动态聚类、多跳传输和节点移动性相结合,提高了LEACH的能量效率。他们还研究了流量和能量异质性对所提出协议的影响。最后,他们模拟了同构和异构场景下的DMH-LEACH协议。仿真结果表明,该协议能够更好地平衡各传感器节点的能量消耗,并显著延长网络的生存期。

Mobile routing algorithm with dynamic clustering for energy large-scale wireless sensor networks
The clustering technique is a key routing method for large-scale wireless sensor networks (WSNs), which strongly extends the network's lifetime and scalability. The fundamental protocol of this technique, which is called low energy adaptive clustering hierarchy (LEACH), is proved as a solution that offers good energy efficiency and consequently expands the network lifetime. As the energy efficiency is deteriorated with the network size, LEACH improvements are becoming so substantial to support the scalability in the large-scale WSNs. The authors propose a new dynamic multi-hop clustering protocol. It exploits both the mobility and the multi-hop communication to prolong the lifetime of the mobile WSN. The proposed protocol, called dynamic multi-hop LEACH (DMH-LEACH), combines the dynamic clustering, multi-hop transmissions, and node mobility to improve the energy efficiency of LEACH. They also study the effect of the traffic and energy heterogeneity on the proposed protocol. Finally, they simulate DMH-LEACH protocol for both homogeneous and heterogeneous scenarios. The simulation results show that the proposed protocol allows to better balance the energy consumption for all sensor nodes and considerably extends the network's lifetime.
