Abstract :
Cognitive radio networks allow unlicensed (secondary) users to opportunistically utilize the idle resource of a licensed network for communication without affecting the quality of service being offered to the primary or licensed users. This paper investigates the effect of mobility on performance of multi-hop cognitive radio network under various propagation models. MPEG4 video; a bandwidth intensive traffic, is tested over these network conditions for secondary users and results are validated using NS2 simulations. Performance metrics used for evaluation include throughput, delay variations etc.
