The paper investigates the issue of physical layer security in spectrum overlay networks.
First, in order to enhance security performance of the primary system, the secondary users …

Combining spectrum sensing (SS) and primary user (PU) traffic forecasting provides a
cognitive radio network with a platform from which informed and proactive operational …

Industrial communication often has to work in an environment where other networks or
radiation create different levels of interference for the data traffic. Additionally, industrial …

With the implementation of 4G mobile networks, the number of M2M users will be much
large in a cell. When massive M2M users try to randomly access simultaneously, this will …

针对无线网络环境中的异构网络提出了一种基于非随机接入方式的频谱接入策略——
对等接入策略, 其中两个异构网络关系是平等的, 网络中的授权用户具有认知功能 …

The federal communications commission (FCC) has predicted that, under the current
regulatory environment, a spectrum shortage may be faced in the near future. This …

The increased densification of wireless networks has led to the development of integrated
