Energy Efficient CCC based AODV Routing Protocol for Cognitive Radio Ad-Hoc Networks
Spectrum mobility in cognitive radio ad-hoc networks introduces additional energy consumption apart from joint channel-path selection. Application data transmission in CR routing is based on channel-route path selected from Common Control Channel (CCC). Hence, CCC plays a pivotal role in selecting and managing energy efficient channel-routes in cognitive radio ad-hoc networks. State-of-the-art CR routing protocols either use 2.4GHz unlicensed dedicated CCC (global) or licensed PU free CCC (local) for channel-path selection which results in higher energy consumption due to longer channel hop-count and higher control channel switching delays.
