Performance Study of Interweave Spectrum Sharing Method in Cognitive Radio
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 5
Abstract
Spectrum scarcity is one of the most critical recent problems in the field of wireless communication. One of the promising approaches to resolve this issue is the use of Cognitive Radio technique. CR technique is performed by Secondary User (SU) to utilize the spectrums more efficiently. SU transmission mode can be broadly divided into two modes: interference avoidance mode (white space) and interference management mode (black and gray space). In this paper, interference avoidance mode is considered. The interference avoidance mode is often referred to as interweave access. In interweave access method, SU finds the spectrum hole by sensing the radio frequency. Here we have used continuous time Markov chain model to calculate QoS parameter of the SU for fixed payload length and exponential distribution payload length for a single channel of PU and SU. Numerical results show that the blocking probability and force termination probability are greater in fixed payload length than in exponential distribution payload length
