Energy harvesting is necessary to make the wireless network self-sustaining and self-organizing regardless of the traditional power grid. How to allocate the limited radio resources in the energy harvesting wireless network is a challenging work. This paper focuses on optimizing the time and power related resources in the multi-cell scenario to maximize the throughput constraining of the changeable...
Resource management in heterogeneous wireless networks has been approached from various angles by the research community. The complexity of the network and the heterogeneity of clients make the conclusive comparison of the various resource allocations challenging. This work introduces superBS, an approach defining a theoretical optimal resource allocation that adheres to the required resource management...
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 cooperative units within the larger network,...
Information theoretic Broadcast Channels (BC) and Multiple Access Channels (MAC) enable a single node to transmit data simultaneously to multiple nodes, and multiple nodes to transmit data simultaneously to a single node respectively. In this paper, we address the problem of link scheduling in multihop wireless networks containing nodes with BC and MAC capabilities. We first propose an interference...
Multiple Input Multiple Output (MIMO) antennasystems are being used to increase the spectral efficiency for the next generation of wireless networks (LTE, WiMAX). In this paper we focus on beamforming techniques for the downlink channel. In particular, we consider the problem of downlink user selection to maximize the downlink resources while satisfying the QoS requirements of all users. We do this...
