无线传感器网络中一种基于地理位置信息的路由算法

Novel Routing Algorithm Based on Geographical for Wireless Sensor Network

无线传感器网络(WSN)能够实时监测和采集网络分布区域内的各种监测对象的信息,有着广泛的应用前景。设计有效的路由算法来降低能量损耗、延长网络的生命周期成为无线传感器网络研究的核心问题。对现有的基于簇类的路由协议中最具代表性的一种--LEACH协议进行了研究,并基于LEACH协议提出了适用于大规模网络的、基于地理位置信息的路由算法(GBCA--Geographical-Based Clustering Algorithm),但仍需进一步完善和改进。仿真实验证明了该算法的有效性。

Wireless sensor network （WSN）, which is utilized in a broad foreground, is able to instantly monitor and collect various information of different objects in the network distributed area. The main techniques of WSN are to design an effective routing algorithm, which will decrease the energy dissipation and prolong the lifetime, one of the most representative clustering routing algorithm is studied, and a routing algorithm based on LEACH for large scale network is introduced, and improvement of this algorithm also is needed. Results of simulation prove the validity
