Energy-Efficient Heterogeneous Cellular Networks with Spectrum Underlay and Overlay Access [PDF]
, 2016 In this paper, we provide joint subcarrier assignment and power allocation schemes for quality-of-service (QoS)-constrained energy-efficiency (EE) optimization in the downlink of an orthogonal frequency division multiple access (OFDMA)-based two-tier ...

Dynamic Bit Allocation for Object Tracking in Bandwidth Limited Sensor Networks
, 2011 In this paper, we study the target tracking problem in wireless sensor networks (WSNs) using quantized sensor measurements under limited bandwidth availability. At each time step of tracking, the available bandwidth $R$ needs to be distributed among the $

Bandwidth allocation in peer-to-peer file sharing networks [PDF]
, 2008 We present a model of bandwidth allocation in a stylized peer-to-peer file sharing network with s peers (sharers) who share files and download from each other and f peers (freeriders) who download from sharers but do not contribute files.

On-line dynamic bandwidth allocation [PDF]
Proceedings 1997 International Conference on Network Protocols, 2002 Network multimedia applications require certain performance guarantees that can be provided through proper resource allocation. Allocation techniques are needed to provide these guarantees as efficiently as possible since resources are limited. This paper presents an allocation method called Dynamic Search Algorithm (DSA+). DSA+ is an on-line algorithm
