Abstract

This paper proposes and analyzes a two-orbit single server queueing model for cognitive wireless networks with cooperative communication. In our model, two secondary users opportunistically utilize a channel which is originally granted to primary users. If a secondary user cannot occupy the channel it returns to the orbit and retries for server after an exponentially distributed time. The retrial rates of the SUs are coupled. We derive a boundary problem for the joint generating functions of the numbers of jobs in the orbits and the state of the server.
具有协同通信的认知无线电网络分析
提出并分析了一种基于协作通信的认知无线网络双轨单服务器排队模型。在我们的模型中,两个辅助用户偶然地利用最初授予主用户的通道。如果次要用户不能占用信道,则在指数分布的时间后返回轨道并重新尝试服务器。SUs的重审率是耦合的。导出了轨道作业数与服务器状态联合生成函数的边界问题。
