Data offloading is an increasingly popular mechanism for meeting the rising demands of cellular users. In order to enable the small players, such as businesses and individual owners to make their services available to the bigger wireless service providers (WSPs) to help offload data, a simple, practical and easy-to-use payment machinery needs to be devised. Existing auction mechanisms usually assume...
This paper considers the problem of designing scheduling algorithms for multi-channel (e.g., OFDM-based) wireless downlink systems. We show that the Server-Side Greedy (SSG) rule introduced in earlier papers for ON-OFF channels performs well even for more general channel models. The key contribution in this paper is the development of new mathematical techniques for analyzing Markov chains that arise...
CSMA-based scheduling is a recently proposed distributed scheduling algorithm that is shown to achieve the maximal throughput. Central to this algorithm is a Markov chain that produces samples from a desired distribution. In this work, we discuss the relationships of the achievable throughput, queueing delay and the mixing time of the Markov chain in a variant of the algorithm. This result suggests...
