摘要

 传感器网络综合了传感器技术、嵌入式计算技术、分布式信息处理技术和无线通信技术,能够协作地实时监测、感知和采集各种环境或监测对象的信息,并对其进行处理,传送到这些信息的用户.传感器网络是计算机科学技术的一个新的研究领域,具有十分广阔的应用前景,受到学术界和工业界的高度重视.
 与传统无线网络相比，传感器网络节点分布稠密、易失效、节点资源有限、难以获得全局信息,因此传统的路由算法并不适合传感器网络,必须针对传感器网络的特性研究新的路由机制与算法。
 本文是基于无线传感器网络的GPS系统定位技术，提出了“子网”和“能量核”的概念,并在此基础上给出了一种传感器网络中基于子网的数据汇聚路由算法，
 本文还介绍了基于此算法的模拟仿真试验，在Microsoft Visual Studio.NET 2003平台上模拟实现了传感器利用此算法的寻径过程，并分析了此算法的一些性能。

 A Subnet based
 Data-Centric Routing Algorithm for Sensor Networks
 
 
 Abstract
 Sensor networks are integration of sensor technology, nested computation technology, distributed computation technology, and wireless communication technology, They can be used for testing, sensing, collecting and processing information of monitored objects and transferring processed information to users. Sensor network is a new research area of computer science and technology and has a wide future for application. Both academia and industries are very interested in it.
 Compared with the traditional wireless network, the density of the sensor nodes distribution is much high, and the sensor nodes are easy to lose efficacy and their resources are limited, which result in great difficulty in accessing global information. Therefore the traditional routing algorithm is not suitable for sensor networks, We must develop some new routing mechanism and algorithm according to the characteristics of the sensor network.
 This paper is based on the GPS positioning technology applied in wireless sensor network, issues the concepts of the "subnet" and "energy-core", and shows a subnet-based data-centric routing algorithm for the wireless sensor networks.
 This paper also describes the simulation experiment based on the algorithm, which is developed on the Microsoft Visual Studio .NET 2003 platform, and shows the routing process of sensors with the Algorithm. Furthermore we analyze the performance of the algorithm in some aspects.
