Ad hoc On-demand Distance Vector (AODV) is a reactive routing protocol that establishes a route based on a requirement. By avoiding counting-to-infinity problem it performs better when compared to most common routing protocols of the Internet such as IGRP, EIGRP, OSPF, RIP and IS-IS. Though reactive and on-demand, AODV cannot capitalize on all available dynamic spectrum resources in cognitive wireless mesh networks yet maintaining a high throughput to route packets. For that reason in this paper, the authors propose an enhanced AODV protocol named AODV-COG (COGnitive) that provides an interface to a route for efficient usage of the spectrum and finding a path with high throughput among the paths with same hop count.
