Security is always a key concern for the networks. This paper concentrates on security threats of Inter Base-station Dynamic Resource Sharing, one of the key features of IEEE-802.22. This paper has identified weak spot related to channel release requests during resource sharing process and has proposed an augmented crossbreed approach at MAC layer protocol in IEEE-802.22. The proposed solution has introduced secure resource sharing process between the neighboring Base Stations. OMNET++ based simulated results shows that proposed augmented security is effective to avoid attacks.
