Cognitive Radio is known the technology that can make possible more intensive and efficient spectrum use through spatial and temporal utilization. In the context of Inter-Base Station Networks (i.e., mesh networks) which consist of heterogeneous multi-radio interfaces, each base station selects each radio interface and channel adaptively in order to take full advantage of all multiple heterogeneous interfaces. In this paper, we have addressed two issues. At first, this paper examines the achievable performance of the new packet switch schemes in mesh topology. Secondly, we investigate the potentiality of dynamic base station relocation approach in order to cope with the change of terminal traffic distribution, and show the impact of packet switch policy and pause time.
