—We study an integrated multiflow network model, in which physical-layer rate control and link-layer medium access and routing decisions are jointly optimized. In particular, we explore the challenges involved in incorporating the three-terminal cooperative paradigm into such a broader resource allocation problem. We present several methods for defining(More)
— The cost of long term leasing of spectrum has proven to be a major road block in broad deployment of 3rd generation cellular radio systems. Similar economical road blocks can be predicted for systems beyond 3G. In order to alleviate the burden of spectrum cost incurred by service providers, there must be a paradigm shift from fixed allocations to a more(More)
— Inter-operator spectrum sharing in a wide-area broadband network is considered in this paper. A packet-based cellular model is developed, emphasizing the shift in the telecommunications industry towards IP-based services. In the framework of this architecture, we show the ideal maximum load that the network can handle without excessive delays, and present(More)
—When designing distributed wireless networks utilizing shared bandwidth, a critical issue is allocating spatial and temporal resources to streaming information flows. We focus on large networks of half-duplex terminals sharing common bandwidth, and study methods for allocating resources on a fine-grained temporal basis, with specific emphasis on managing(More)
—An integrated multiflow network model synthesizing physical layer rate control and link layer access control is presented, permitting the study of resource allocation in large networks while allowing multi-terminal cooperation at the physical layer. We discuss how to incorporate the cooperative unit into the broader scheduling and routing framework as a "(More)
—We present a wide-area, multiflow ad-hoc network model leveraging information-theoretic rate control, emphasizing interfering rather than colliding transmissions. We seek to allocate resources in this network by optimizing scheduling, routing and power control to solve the max-min throughput problem for all flows involved. In general, our time-slotted,(More)
— Recently, new network topologies including relays and meshed networks have emerged as a key technology receiving a lot of attention due the increasing need for additional resources such as spectrum and required high data-rates. In this paper, we identify and describe the novel network topologies that will be able to accommodate the foreseen high data(More)
