Spectrum-Aware Routing Protocol for Cognitive Ad-Hoc Networks

This paper provides a novel spectrum-aware routing protocol (SARP) for cognitive ad-hoc networks. It consists of two parts. One is the intelligent multi-interface selection function, which is used to assign an appropriate interface to a route to efficiently allocate the channels. The other is the intelligent multi-path selection function, which is used to select an appropriate path to route packets. This novel multi-channel multi-interface routing protocol is aware of both spectrum and space. Based on simulation results, SARP is able to improve network performance significantly.
