In this article, we propose a semi-distributed resource allocation framework for the resource optimization in multicell uplink cooperative orthogonal frequency division multiplexing systems. Specifically, we model the resource allocation framework as an optimal problem. This optimization problem is divided into two steps. First, using integer programming, we achieve the joint relay selection an...

Buffer allocation in WiMAX maximizes the throughput by achieving high link utilizationof system and minimizes the power consumption. In this paper, Traffic Based QoS Specific Adaptive Buffer Allocation in WiMAX networks is proposed to increase the system throughput by using an adaptive buffer allocation strategy. The buffer management block initially allocates buffer to the flow requests based ...

The problem of chunk-based resource allocation for the uplink of Long Term Evolution is investigated. In this paper, a combined order using the promethee method and analytic hierarchy decision for chunk allocation algorithm is proposed. The utility of each order is sorted based on promethee method approach so that the utility of each order could be approximated as the average of all criteria on...

We consider a generalized layered Space-Time (GLST) architecture with parallel Space-Time (ST) codes and derive an optimal power allocation (PA) scheme over the SpaceTime encoders to minimize the overall frame error rate. We prove that the optimal power allocation scheme will equate the derivatives of the frame error rate functions of all the ST codes. From simulation, we show that the derived ...

In this paper, we present a model based on utility functions and pricing for resource allocation in the downlink of DS-CDMA systems carrying elastic traffic, where power and data rate are controllable resources. The goal of our model is to achieve the social optimal resource allocation via the adjustment of resource price, which is similar to the market model in microeconomics. According to whe...

This chapter reviews fundamental protocol engineering aspects and presents resource allocation approaches for wireless relay networks. Important cooperative diversity protocols and their typical applications in different wireless network environments are first described. Then, performance analysis and QoS provisioning issues for wireless networks using cooperative diversity are discussed. Final...

ETRI Journal, Volume 24, Number 4, August 2002 In this work, we present a novel approach to the bit allocation problem that aims to minimize overall distortion subject to a bit rate constraint. The optimal solution can be found by the Lagrangian method with dynamic programming. However, the optimal bit allocation for block-based interframe coding is practically unattainable because of the inter...

For high speed mobile communication applications, the data rate can be increased by using multiple channels (or time slots) instead of one channel. To reduce the high blocking rate of multiple channels assignment, exible resource allocation strategies have been proposed. This paper proposes the Equal Resource Sharing Allocation scheme (ERSA scheme) for exible resource allocation. The ERSA schem...
