Title Simulation on Clustering Topology Algorithm for Wireless Sensor Networks
Abstract Wireless sensor networks is wireless networks composed of stationary or moving sensors to self-organization and multi-hop manner, its purpose is perception, acquisition, processing and transmission network coverage area perceive objects, sent to the user . Sensors, sensing object and the observer constitute three important elements of the wireless sensor networks . Unicom degrees to meet and network coverage under the premise of the main research topics topology wireless sensor clustering algorithm, designed to rational and efficient use of network energy, delay the survival of the entire network lifetime.
This paper is pided into four parts: First, the first part of this paper introduces research background of the wireless sensor network, significance and current domestic and international wireless sensor network clustering algorithm based research status; Secondly, the second part of this paper introduces the radio sensor network topology algorithm clustering architecture, the general classification, design goals and requirements as well as a simple clustering algorithm papers and analysis and comparison of typical algorithms; once again, the third part of this paper mainly analyzed the typical clustering algorithm - LEACH agreement of the working mechanism, models, algorithms, and application performance network simulation software simulation; Finally, the fourth part of this article focused on the inadequacies of the LEACH protocol, made their algorithm and simulation comparison summary.

1.1 研究背景
随着大量的相关研究不断深入，人们对无线传感网络的认识也逐渐浮出水面，无线传感网络是集成了计算机、通信和信息感知三大学科中众多科学知识的新兴领域，简单点来说，无线传感网是由大量的静止的或移动的廉价微型传感器节点组成，这些节点部署在监测区域内，通过无线通信方式形成。无线传感网是一个多跳的自组织的网络系统，其是为了协作地感知、采集、处理以及在传输网络覆盖地理区域内的感知对象的监测信息，并最终把这些信息发送给网络所有者的。 LEACH协议无线传感网分簇拓扑控制算法仿真研究:http://www.youerw.com/tongxin/lunwen_70203.html
