Cognitive radio ad hoc networks (CRAHNs) are multi-hop, dynamic and self-configurable networks, which can communicate without any infrastructure support. Most of the research in CRAHNs has been already carried out on physical and media access control layers, but without effective routing protocols we cannot take full advantage of CRAHNs. In this paper, we discuss the problems in already proposed routing protocols for cognitive radio networks and proposed a novel protocol: Delay and Energy based Spectrum Aware Routing Protocol (DESAR), which consider both delay and energy for the computation of efficient path between source and destination. Simulation results show that DESAR protocol performs better than existing protocol in term of end-to-end delay.
