无线传感器网络与自组织网络的研究现状

A Survey on Wireless Sensor Network and Ad Hoc Network

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,是计算机科学技术的一个新的研究领域;自组织网络是一种移动、多跳、自律式系统,两者均具有十分广阔的应用前景。文章对传感器网络和自组织网络的概念、特征和发展动态等问题进行了介绍,重点分析了目前这两种网络的关键技术和研究现状。文章认为:传感器网络在特殊领域有着传统技术不可比拟的优势,而无线自组织网络通过临时组网的方式在恶劣环境中支持移动节点之间的无线传输,应用范围广阔。对这些网络的研究是中国未来高技术民用和军事发展的需要。

Sensor network, which is made by the convergence of sensor, embedded computing system, distributed information processing and wireless communication technologies, is a novel technotogy about acquiring and processing information. Ad hoc network is a mobile, multi-hop and autonomous decentralized system. Both networks have great application potential. The concepts, characteristics and development status of the sensor networks and Ad hoc networks are introduced. The paper thinks that the sensor network dominates in special application fields while the Ad hoc network without fixed infrastructure supports wireless transmission between mobile nodes under bad environments. The research on the sensor and Ad hoc networks arenecessary for the development of high technologies in both civil and military fields of China.
