It is well-known that throughput of wired multi-hop, multi-commodity networks can be maximized by employing back-pressure scheduling. With this approach, packets belonging to different destinations are dynamically routed/scheduled in a network based on buffer occupancies and link quality. There has been a considerable amount of research on applying back-pressure scheduling in the wireless environment;...
Network coding is a method that promises to achieve the min-cut capacity in multicasts. However, pushing towards this gain in throughput comes with two sacrifices. Delay suffers as the decoding procedure requires buffering and is performed in batches of coded packets, and unfairness prevails in terms of delay increases between receivers with worse channel conditions and those with better channel conditions...
Dynamic spectrum access (DSA) is important for spectrum management in the future. DSA with prioritization for two types of radio systems are presented through analytical formulation. The DSA with prioritization model is solved numerically using a two-dimensional Markov chain. Grades of service (GoSs) like system airtime and blocking probabilities are considered. The performance of these GoS measures...
