Publication Abstract:
Throughput maximization is one of the core challenges in cognitive radio ad hoc networks (CRANs), where local spectrum resources are changing over time and locations. This paper proposes a spectrum and energy aware routing (SER) protocol for CRANs, which involves spectrum aware, and energy-efficient route selection, and channel-timeslot assignment. A good routing protocol should be aware of the interference as well as the end-to-end delay. The proposed joint spectrum and energy aware routing with channel-timeslot assignment can balance the energy consumption, eliminates contention between users, and decompose contending traffics over different channels and timeslots. As a result, the proposed scheme leads to significant increases in network throughput and decreases the end-to-end delay. The simulation results show the effectiveness of our proposed approach with good generalization ability.
