MELEACH:一个高效节能的WSN路由协议

无线传感器网络(简称WSN)一种资源严重受限的网络,特别是在供能方面.因此,如何有效地使用传感器节点的能量以延长WSN的生存时间,一直是WSN路由协议研究所关注的焦点. LEACH1-2]作为一种WSN路由协议,以其优秀的节能效果和简单的规程而得到广泛的认可.本文基于LEACH提出了一个新的路由协议MELEACH(More Energy-efficient LEACH). 通过进一步缩短无线通信的平均距离并进一步改善节点间的负载平衡, MELEACH在保持LEACH原有优点的基础上实现了更好的节能效果.分析和实验表明,一个WSN在MELEACH下的生存时间要比在LEACH中长50%以上.

MELEACH: An Energy-efficient Routing Protocol for WSNs

Wireless Sensor Networks (WSNs) are severely resource constrained, especially in the aspect of power supply. How to effectively manage power consumption so that the lifetime of a WSN can be maximized is a central topic for research in WSN routing protocols. As an attractive WSN routing protocol, LEACH 1~2] has been widely accepted for its energy efficiency and simplicity. Based on LEACH we propose a new routing protocol MELEACH (More Energy-efficient LEACH), which has a better performance on energy efficiency without losing the advantages of LEACH. MELEACH improves LEACH by further reducing the mean transmission distance and improving the load balance between sensor nodes, Our analysis and simulation results have shown that the lifetime of a WSN running in MELEACH is at least 50% longer than that running in LEACH.
