To fully utilize radio resources by intelligently filling in as much radio spectrum gaps as possible, the concept of cognitive radio network has been well accepted. A challenge inherent in this technology is how to build a mechanism that can allocate resource by learning and adapting to a specific radio transmission environment. In this paper, we propose a cognitive resource management scheme that...
The importance of tactical networks that support military operations is well known in the DoD community for their ability to rapidly deploy anywhere at anytime without pre-existing infrastructure. Tactical networks provide a battle space where warfighters possess dynamic and ad hoc mobile communications to support operations against a broad array of threats. Managing mobility to provide undisrupted...
Ad hoc network nodes work cooperatively to route data packets and maintain network functions. However, this cooperative behavior can be a potential vulnerability for security breaches. Moreover, network node capacity differences may result in an asymmetrical defense capability. Even network nodes that are capable of running a strong security mechanism may choose not to use it because of impacts on...
