Spectrum and Delay Efficient Routing Protocol for Mobile Cognitive Ad-Hoc Networks

Abstract

The ad hoc mobile cognitive network is an advanced network technology for the Federal Communications Commission (FCC) problem of frequency deficiency. Cognitive radio networks are cognitive networks that select their network parameters based on the network environment. In a cognitive radio network, two users, the primary and the secondary or the cognitive user, gain access to the spectrum available to communicate with each other when the primary user accesses the spectrum. The secondary user should leave the spectrum and use the spectrum for the spectrum if the spectral hole is available for transmission. Therefore, routing in cognitive networks is a challenge and a challenge in mobile cognitive networks because of node mobility, the primary user interface, and the lack of spectrum. A delay minimized routing protocol is proposed for minimum delay route selection between the source and destination, which is improved version of AODV. The numerical and ns2 simulation results for the proposed protocol significantly state that delay minimized routing protocol (DMR) is better in terms of average end-to-end delay and average throughput.
