One of the methods to solve the problem of spectrum demand is spectrum sharing and can be achieved using Cognitive Radio (CR) network. The problem in CR network is physical layer security. The physical layer security can be improved using relays in the secondary network. There are two types of relay slection schemes which are Single Relay Selection (SRS) and Multiple Relay Selection (MRS) schemes...
In the present day wireless communication networks, the main objective is to support different multimedia services with various requirements of Quality of Services and varying bandwidth requirements. The key role in effective resource management of WiMAX network is to enhance the performance of network. Gateway (GW) relocation of Access Service Network (ASN) includes changing the Anchor Point (AP)...
In recent times, the popularity of Cognitive Radio has been increased because of its spectrum sensing characteristics. Using CR, the spectrum is utilized efficiently and maintain efficient communication when the primary user is not using the spectrum. In this paper, Bayesian detector is used for detecting the presence of primary user's signal. This approach is optimal when PU is not using the spectrum...
