Collision Avoidance Algorithm with Jitter in Multi- hop Cognitive Radio Network

Cognitive radio techniques make full use of spect rum 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 info rmation needs to be relayed over multiple wireless links and secondary users have to co-ordinate themselves in a distributed manner, an improvement in throughput i s achieved by reducing packet loss, through the addition of sm all jitter 1µs at the time of transmission for a ne twork with a set of 6 nodes. Initially we describe the multi-hop cog nitive 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.
