Neighbor node discovery mechanism based delay aware routing protocol (DARP — NND) for cognitive radio ad hoc networks
Muthukumaran Kannan, B. Rosiline Jeetha · 2016
Cognitive Radio ad hoc network is a sort of wireless network. Cognitive radios have the ability to sense the wireless medium. Routing is the major research area and ensuring quality-of-service (QoS) is a challenging problem. This paper proposes a neighbor node discovery mechanism based delay aware routing protocol in order to provide QoS in such network. Primary QoS metrics such as throughput and delay can be put into consideration for evaluating the performance of the proposed protocol DARP-NND. Simulations are passed out by means of NS2 and the outcomes confirm that the proposed protocol achieves improvement in provisions of increased throughput and reduced delay.
