Coalition Formation Games for Cooperative Spectrum Sensing in Cognitive Radio Networks,rks (CRNs). This chapter considers a CRN with multiple primary users (PUs) and multiple secondary users (SUs) and presents two cooperative spectrum sensing and access (CSSA) schemes. The first CSSA scheme allows each SU to sense one channel and is formulated as a hedonic coalition formation game, wh

Coexistence of Heterogeneous Cellular Networks,opportunistic access to spectrum using cognitive radio (CR) technology. When heterogeneous cellular networks that are based on different wireless standards operate in the same spectrum band, coexistence issues can potentially cause major problems. Enabling coexistence via direct coordination between

Cognitive Management Strategies for Dynamic Spectrum Access,), it conciliates the existing conflict between the ever-increasing spectrum demand and the currently inefficient spectrum utilization. The basic idea of DSA is to provide proper solutions that allow sharing radio spectrum among several radio communication systems and optimize the overall spectrum u

Cognitive Radio and TV White Space (TVWS) Applications,spectrum capacity is required. Service providers are experiencing deployment blockages due to insufficient bandwidth being available to accommodate such devices. . (TVWS) represents an opportunity to supplement existing licensed spectrum by exploiting unlicensed resources. TVWS spectrum has material

Cognitive Radio Network Security, an opportunistic manner. Although security in CRNs has received less attention than other areas of CR technology, the need for addressing security issues is evidenced by two facts. First, as for any other type of wireless network, an open channel is used for communications that can easily be access

Collaborative Spectrum Trading and Sharing for Cognitive Radio Networks,ach, unlicensed users (a.k.a. secondary users) offer licensed users (a.k.a. primary users) with monetary rewards or improved quality of services (QoSs) in exchange for spectrum access rights. In this chapter, we present a comprehensive introduction to spectrum trading. First, we provide a brief intr
