摘要

Opportunistic spectrum access aims to exploit the instantaneous spectrum availability using sophisticated signal processing and networking techniques. Cognitive MAC that enables instantaneous detection and efficient utilization of spectrum opportunities is one of the key components of opportunistic spectrum access. In this paper, we pursue a crosslayer approach that integrates opportunity assessment and opportunity allocation for optimal spectrum utilization. We develop optimal cognitive MAC protocols for multihop ad hoc networks.
