LEACH协议，全称是“低功耗自适应集簇分层型协议” (Low Energy Adaptive Clustering Hierarchy)，是一种无线传感器网络路由协议。基于LEACH协议的算法，称为LEACH算法。

　保证服务质量的QoS 路由(Quality of Service Routing) 是网络中解决QoS 问题的一项关键技术. QoS 路由 的主要目标是为接入的业务选择满足服务质量要求的传输路径,同时保证整个网络资源的有效利用. 度量参数选择问 题、寻路问题和路由信息不准确问题是QoS 路由中的几个主要研究内容. 本文围绕这三个方面,介绍了QoS 路由中的 主要问题及相关的解决办法,并探讨了今后QoS 路由可能的研究方向.-To ensure the quality of service QoS routing (Quality of Service Routing) is a network address QoS issues a key technology. QoS routing the main objective is to access business options to meet the requirements of the transmission path quality of service, while ensuring that the entire network efficient use of resources. metric parameters of choice, look for road and routing information is not accurate QoS routing problem is that several major research contents. This paper focus on three aspects, introduced the main issues in QoS routing and related solution, and to explore possible future research directions QoS routing.
