Sharp: a Joint Spectrum Allocation, Handover and Routing Protocol for Cognitiveradio Ad-hoc Networks

In this paper, A joint Spectrum allocation, horizontal/vertical Handover and opportunistic multi-hop Routing Protocol (SHARP) is proposed to address a few of the most important challenges of multi-hop ad-hoc, fixed or vehicular cognitive radio networks, such as, maximization of spectrum utilization and throughput. Utilizing the proposed joint velocity and average received power (ARP) estimation algorithms a novel spectrum sensing method is presented that is used for efficient dynamic resource allocation and routing. Numerical evaluation and simulation results, demonstrate that proposed scheme achieves significant improvements over conventional solutions, specifically with the presence of severe AWGN and interference in addition to consideration of a dense urban Manhattan-grid model as a PU/SU environment.
