Abstract
With the rapid growth of wireless networks and the increasing demand for wireless services, there will be an acute shortage of spectrum resources in the near future. A promising solution is to use the cognitive radio technology to arm the mesh nodes with opportunistic spectrum access capability, which leads to a more flexible access to spectral resources. In this paper, we investigate the joint interface assignment and channel allocation problem in cognitive radio mesh network. In order to ensure the QoS quality for each call, we propose a novel nested optimization technique based on genetic algorithm to find the optimal resource allocation. Extensive simulation results show that the proposed algorithm converges fast and approaches the global optimal solution efficiently.
