Prediction-Based Topology Control and Routing in Cognitive Radio Mobile Ad Hoc Networks

Recent research activities on Cognitive Radio (CR) have mainly focused on opportunistic spectrum access and spectrum utilization. However, CR technology will have a significant impact on upper layer performance in wireless networks, particularly in Mobile Ad hoc NETworks (MANETs). In this paper, the authors study topology control and routing issues in CR-MANETs and propose a distributed Prediction-based Cognitive Topology Control (PCTC) scheme to provision cognition capability to routing in CR-MANETs. PCTC is a middleware-like cross-layer module residing between CR module and routing.
