摘要
频谱感知意识的无线传感器网络可提供无线频谱信息的采集、监测、查询、统计、分析和分发服务,显著提高频谱资源的利用率和改善网络应用的服务性能。本文针对行业应用需求,对具有频谱感知能力的无线传感器网络的体系结构和网络协议设计等问题进行了初步分析研究,明确了采用分层网络架构和跨层协议设计方法,并对网络系统涉及的频谱信息感知、信息汇聚、路由选择和网络管理等问题进行了探讨。
Spectrum cognition-aware wireless sensor network can provide wireless spectrum information collection, monitoring, queries, statistics, analysis, and distribution services, significantly improving the utilization of the scare spectrum resource and service performance of network applications. In this paper according to the application needs of industry, spectrum-aware wireless sensor network architecture and network protocols design problems are analyzed and studied preliminarily and hierarchical network structure and cross-layer protocol design methods are identified. In addition, spectrum cognition, information aggregation, routing selection and network management issues involved in network system design are discussed.
