Abstract

Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is considered as one of the most important protocols that are frequently used in the Wireless Sensor Network (WSN). Many protocols were developed to modify and improve the LEACH protocol. The multi-hop technique (MHT-LEACH) is one of these protocols, which appeared to improve the performance of the LEACH protocol. In this paper, an improved multi-hope technique (IMHT-LEACH) is proposed. Instead of distributing all the Cluster Heads (CHs) into two levels as in the MHT-LEACH, the IMHT-LEACH distributes all the CHs into a number of levels. It suggests a new technique to route the data to the Base Station (BS) through the levels. Simulation results indicate that the IMHT-LEACH improves the lifetime, stability and throughput of the WSN comparing with the conventional LEACH and the MHT-LEACH protocols.
IMHT:改进的无线传感器网络MHT-LEACH协议
低能量自适应聚类层次(LEACH)协议是无线传感器网络(WSN)中常用的重要协议之一。开发了许多协议来修改和改进LEACH协议。多跳技术(multi-hop technique, MHT-LEACH)就是其中的一种,它的出现提高了LEACH协议的性能。本文提出了一种改进的多希望技术(IMHT-LEACH)。与MHT-LEACH中将所有簇头(CHs)分布到两个级别不同,IMHT-LEACH将所有CHs分布到多个级别。它提出了一种通过关卡将数据路由到基站(BS)的新技术。仿真结果表明,与传统LEACH协议和MHT-LEACH协议相比,IMHT-LEACH协议提高了无线传感器网络的寿命、稳定性和吞吐量。
