Paper Title : Hybrid strategy for reliable packet transfer and packet loss reduction in cognitive radio Ad-Hoc Network
Author Name : C.V. Subhaskara Reddy, M. V. Subramanyam and P. Ramana Reddy
Abstract :

Cognitive radio ad-hoc network is characterized by frequent routing disruptions introduced due to intermittent spectrum availability. Routing disruption increases the packet loss and affects the reliability of the network. This work adopts multiple strategies of reliable link based selective multi path routing, secondary user caching packets, packet redundancy based recovery and adaptive packet generation based congestion control. Recovery is given more importance compared to retransmission in reconstructing the lost packet. Congestion is controlled by applying two strategies of rate control and route participating factor. Reliability of routing is improved by predicting the link failure and handling the failure using selective backup route. With this adoption of multiple strategies, the proposed solution not only minimizes the packet loss but also achieves 3% higher packet delivery ratio, 9% lower end-to-end delay and 7.5% lower communication overhead compared to existing one in cognitive radio ad-hoc network.

Keywords : Cognitive radio Ad-Hoc network, Reliable link routing, Cooperative caching at SU’s, Loss recovery.
