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.
