This paper studies spectrum sharing for providing better quality of experience in 5G
networks, which are characterized by multidimensional heterogeneity in terms of spectrum …

An efficient channel allocation scheme for vehicular networks is required due to the
popularization and rapid growth of the corresponding applications in recent years. We …

Hybrid interweave-underlay spectrum access in cognitive radio networks can explore
spectrum opportunities when primary users (PUs) are either active or inactive, which …

Energy efficiency as well as fast data transmission is vital to green communications-based
applications for Internet of Things (IoT). Wireless sensors, which constitute one of the …

Cognitive radio and dynamic spectrum access can reform the way that radiofrequency
spectrum is accessed. Problems of spectrum scarcity, coexistence, and unreliable wireless …

This monograph addresses the spectrum-scarcity problem by providing a comprehensive
overview of spectrum resource management in Cognitive Radio Sensor Networks (CRSNs) …

One significant challenge in cognitive radio networks is to design a framework in which the
selfish secondary users are obliged to interact with each other truthfully. Moreover, due to …

The data sequence of spectrum sensing results injected from dedicated spectrum sensor
nodes (SSNs) and the data traffic from upstream secondary users (SUs) lead to …

In spectrum sharing networks with relay cooperation, primary users can benefit from the
assistance of secondary users while secondary users accessing the primary bandwidth to …

采用CTMC 模型分析了网络状态的统计特性, 考虑各个次用户感知能力的差异性,
分别从主用户和次用户的角度出发, 建立了2 个关于次用户调度方案的整数规划问题 …
