In Part I 1] of this paper, a class of multicarrier systems was proposed to study the eeect of the method of diversity allocation on the performance of coherent multiuser communication systems operating over fading channels. In this part of the paper, optimization over the proposed class of systems is considered for a xed number of users per unit bandwidth. The rst case studied is a system wher...

In Part I of this paper, a class of multicarrier systems was proposed to study the effect of the method of diversity allocation on the performance of coherent multiuser communication systems operating over fading channels.

In this paper, we consider the problem of location-dependent opportunistic bandwidth sharing between static and mobile (i.e., moving) downlink users in a cellular network. Each cell of the network has some fixed number of static users. Mobile users enter the cell, move inside the cell for some time and then leave the cell. In order to provide higher data rate to the mobile users, we propose loc...

The general problem we consider is the analysis of a model in which there are several routes in a network, on each route elastic flows arrive randomly according to some arrival process, and each flow transfers a finite volume of data sampled from some distribution. We are interested in computing a measure of average flow throughput on each route, for a given bandwidth sharing mechanism. Such mo...

One of the challenges in the design of switches/routers is the efficient and fair use of the shared bottleneck bandwidth among different Internet flows. In particular, to provide fair bandwidth sharing, different buffer management schemes are developed to protect the well-behaved flows from the misbehaving flows. However, most of the existing buffer management schemes cannot provide accurate fa...

This paper proposes efficient resource allocation techniques for a policy-based wireless/wireline interworking architecture, where quality of service (QoS) provisioning and resource allocation is driven by the service level agreement (SLA). For end-to-end IP QoS delivery, each wireless access domain can independently choose its internal resource management policies to guarantee the customer acc...
