摘要
无线传感器网络是一门获取和处理信息的新兴技术。为了满足应用的要求,设计人员必须对相关的网络结构、协议和功耗等性能特点全面深入了解。详细阐述了无线传感网络的通信结构,传感节点的组成结构及可能的实现方案,分析了各种拓扑结构的优缺点,基于分层方法给出了一种通信协议栈;在与现有无线通信模型比较的基础上,得出了无线传感网络节点数量大、体积小、易失效、计算能力有限及对能量敏感的特点,为通信结构和具体协议的设计提供了指导。
Wireless sensor networks (WSN) is a novel technology about acquiring and processing information. The designer of WSN must have a thorough understand about architecture, protocol and characteristics of WSN. This paper describes communication architecture, component of node and available building scheme for WSN in detail, analyzes the characteristics of all topologies, and presents a protocol stack based on layer theory. The popular wireless communication models are discussed, characteristics and features are also analyzed, which provide a guidance for designer.
