Orthogonal Frequency Division Multiplexing (OFDM) is used for both 802.11 and 802.16 wireless network standards and is being evaluated for Fourth Generation (4G) networks such as those being proposed in the 3GPP and 3GPP2 wireless standards bodies. In both uplink and downlink directions, resources can be allocated in three dimensions, frequency, time and power. The uplink resource allocation pr...

An ATM-type multiplexer, with nite buuer and multimedia traac input, is investigated for packet loss and delay. It can also be subject to input rate regulation, overload control, and dynamic allocation of transmission bandwidth. This system model is fundamental to the ATM design, but has not been analyzed satisfactorily. In 1], an eecient and versatile technique, the folding algorithm, is devel...

Buuer management schemes are needed in shared-memory ATM switches to regulate the sharing of memory among diierent output port queues and among traac classes with diierent loss priorities. Earlier we proposed a single-priority scheme called Dynamic Threshold, in which the maximum permissible queue length is proportional to the unused buuering in the switch. In this paper, we propose, analyze an...

In this paper, we study the problem of resource allocation and control for an ATM node with regulated traffic. Both guaranteed lossless service and statistical service with small loss probability are considered. We investigate the relationship between source characteristics and the buffer/bandwidth trade-off under both services. Our contributions are the following. For guaranteed lossless servi...

This paper proposes a Particle Swarm Optimization (PSO) based technique for the optimal allocation of Distributed Generation (DG) units in the power systems. In this paper our aim is to decide optimal number, type, size and location of DG units for voltage profile improvement and power loss reduction in distribution network. Two types of DGs are considered and the distribution load flow is used...

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 that dynamically adjusts the resource allo...

QoS guarantees for wireless mobile applications require advance resource allocation. In this paper, we propose a signaling protocol for resource allocation in wireless environments, based on RSVP. It addresses the issue of scalability in RSVP by ensuring lower per-connection state storage and lesser control messaging. It provides wireless applications parameters such as loss negotiability, loss...

Address allocation is an essential part in maintaining a mobile ad hoc network (MANET) effectively, and several address allocation schemes have been proposed. In this paper, we present a set of analytical models to evaluate the efficiency of address allocation schemes. The derived models quantitatively characterize the efficiency of four popular address allocation schemes in terms of latency an...

A robust control allocation scheme is developed for rigid spacecraft attitude stabilization in the presence of actuator partial loss fault, actuator failure, and actuator misalignment. First, a neural network fault detection scheme is proposed, Second, an adaptive attitude tracking strategy is employed which can realize fault tolerance control under the actuator partial loss and actuator failur...
