Optimization of Resource Allocation in Multihop HARQ Relay Networks with a Delay Constraint

Resource Allocation in Sensor Networks Using Distributed Constraint Optimization

Several algorithms have been proposed for solving constraint satisfaction and the more general constraint optimization problem in a distributed manner. In this paper we apply two such algorithms to the task of dynamic resource allocation in the sensor network domain using appropriate abstractions. The aim is to effectively track multiple targets by making the sensors coordinate with each other ...

Resource Allocation in Wimax Relay Networks

WiMAX is a promising wireless technology to provide high-speed, reliable communications in large areas. Relay stations can be deployed in a WiMAX network to extend its coverage and improve its capacity. Orthogonal Frequency Division Multiplexing Access (OFDMA) enables better channel utilization and exploits the benefits of channel diversity and user diversity. A smart adaptive antenna provides ...

Resource Allocation in Wireless Relay Networks

Optimal Max-Min Fair Resource Allocation in Multihop Relay-Enhanced WiMAX Networks

In this paper, an optimal resource allocation scheme is proposed for WiMAX networks enhanced with non-transparent relay stations (RSs). We first focus on two-hop relaying networks, since this scenario has the largest throughput gain. Furthermore, many researchers have proposed different resource allocation schemes in two-hop relaying networks, and, thus, we can compare the performance of our pr...

Joint power, subcarrier and subframe allocation in Multihop relay networks

In this paper we study the problem of subframe, subchannel and power allocation in OFDMA-based multihop relay networks. The system consists of a base station (BS), a number of relay stations (RS) and mobile stations (MS). We consider frame by frame scheduling, where the frame is divided into two subframes such as BS-RS and RSMS subframes. We study two different problems, satisfying link rate re...
