Cognitive ad hoc networks have been attracting interests in recent years. Designing an efficient routing protocol for cognitive ad hoc networks is important for full utilization of free wireless resources. A protocol considering primary user (PU) flows and channel assignment incurred network connectivity issue in the route selection is still missing. In this paper, we propose AODV-cog, a cognitive routing protocol for CSMA/CA ad hoc networks based on AODV. AODV-cog utilizes the availability of multiple channels by considering the effect on the primary users. AODV-cog chooses a route by considering available channel bandwidth and future channel utilization. AODV-cog switches channels for secondary user flows when network congestion is occurred. We use network simulations to show the advantage of AODV-cog over existing alternatives. |
