In this paper, we investigate the gateway selection problem for throughput optimization in multi-radio multichannel wireless mesh networks. In contrast to the various methodologies in the literature, we not only explicitly model the delay overhead that is incurred during channel switching, and consider this delay-related issue in the design of our mechanism but also employ the most reliable interference...
In cognitive radio cellular networks (CogCells), primary users (PUs) rarely utilize all the assigned frequency bands at a certain time and a location. The spectral inefficiency caused by the spectrum holes motivated cognitive radio technology (CR) that presents unlicensed secondary users (SUs) an opportunity for using spectrum holes. CR makes the SUs to find and use the spectrum holes without interrupting...
Wireless mesh networking (WMN) is an emerging communication paradigm to enable resilient, cost-efficient and reliable services for the future-generation wireless networks. We study the minimum-latency communication primitive of gossiping (all-to-all communication) in known topology WMNs, i.e., where the schedule of transmissions is pre-computed in advance based on full knowledge about the size and...
Wireless mesh networks (WMNs) is an emerging communication paradigm to enable resilient, cost-efficient and reliable services for the future-generation wireless networks. We study the minimum-latency communication primitive of gossiping (all-to-all communication) in multi-hop ad-hoc WMNs. Each mesh node in the WMN is initially given a message and the objective is to design a minimum-latency schedule...
