Collision Avoidance Algorithm with Jitter in Multi-hop Cognitive Radio Network
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 12
Abstract
Cognitive radio techniques make full use of spectrum resources via dynamic spectrum access technique. This paper presents a collision avoidance algorithm with the addition of jitter in multi-hop cognitive network. In a multi-hop Cognitive Radio system in which information needs to be relayed over multiple wireless links and secondary users have to co-ordinate themselves in a distributed manner, an improvement in throughput is achieved by reducing packet loss, through the addition of small jitter 1µs at the time of transmission for a network with a set of 6 nodes. Initially we describe the multi-hop cognitive radio network then various issues for Design of system are considered. From the result it is observed that the throughput for a multi-hop cognitive radio network achieved up to 28x 103 bits/s with the set values of 6 nodes.
