title = "Reliable Channel Selection and Routing for Real-Time Services over Cognitive Radio Mesh Networks",
abstract = "In Cognitive Radio Mesh Networks (CogMesh), Secondary Mesh Routers (SMRs) can opportunistically utilize the licensed spectrums for the traffic of the Secondary Mesh Users (SMUs). How to guarantee Quality of Service (QoS) for real-time services over CogMesh is still an opening issue. In this paper, we present a discrete-time vacation queueing system to abstract the Primary User (PU) interruption to SMR data transmission. Moreover, we formulate the optimization problem of joint channel selection and routing, to achieve minimum end-to-end delay for SMR while guaranteeing the channel unavailability. A heuristic method is proposed to solve this problem and results show our proposed method performs the closest to the scheme using optimization tool, and outperforms the minimal unavailability scheme and minimal delay scheme in terms of end-to-end delay and solution rate.",
