为了在无线传感应用中充分利用认知无线电（CR）技术，采用合适的网络体系结构和高效的工作模型是一项必不可少的任务。鉴于在不同的工作场景下，各种流量类型所必需的不同QoS要求，本文综述了认知无线电传感器网络（CRSN）实现所面临的相关挑战以及常见的CRSN网络体系结构模型。在业务连续性概念的启发下，提出了一种新的体系结构，旨在实现复杂性、成本、生命周期、可伸缩性和QoS满意度之间的充分平衡。该工作的贡献通过支持的模拟来进行数值评估，以展示通用标准的性能。
Admitting the appropriate network architecture with an efficient working model is an essential task to enable exploiting Cognitive Radio (CR) technology in the wireless sensing applications. Given the different QoS requirements essential for a variety of traffic types in different work scenarios, this paper reviews the related challenges facing the Cognitive Radio Sensor Network (CRSN) implementation and the common proposed network architecture models for CRSN. It also proposes a new architecture aims at achieving a sufficient balancing between complexity, cost, lifetime, scalability and QoS satisfaction with the inspiration of Business Continuity concept. The contribution of the work is numerically evaluated with a supported simulation demonstrating the performance of a common standard.
