MCSAAR: Multi-Coefficient Spectrum Aware Based Shortest Anypath Routing in Multi-hop CRNs

Abstract

Wireless communication technology has grown tremendously with an advancement of better communication quality. It depends on the available spectrum bands but due to increased demand, the spectrum scarcity has become a challenging issue. Recently dynamic spectrum management is proposed as a recommended solution by Federal Communication Commission (FCC) which can enhance the spectrum management. To overcome the identified problem, we look at Cognitive Capacity Harvesting network and develop a multi-hop cognitive radio network routing protocol. The proposed routing protocol Multi-Coefficient Spectrum Aware based shortest Anypath Routing in Multi-hop CRNs (MCSAAR) is designed based on the link quality, energy consumption and trust values for identifying the next-hop. The proposed approach performance is compared against existing anypath routing schemes. The obtained simulation result ensures better efficiency in terms of packet delivery ratio and end-to-end delay
