In this paper, a novel adaptive control allocation framework is proposed. In the adaptive control allocation structure, cooperative actuators are grouped and treated as an equivalent control effector. A state feedback adaptive control signal is designed for the equivalent effector and allocated to the member actuators adaptively. Two adaptive control allocation algorithms are proposed, which gu...

This paper investigates the problem of dynamic multiuser subchannel allocation in the downlink of OFDM systems. The assumptions are that the channel model is quasi-static and that the base station has perfect channel information. In traditional TDMA or FDMA systems, resource allocation for each user is nonadaptively fixed, and the water-filling power spectrum is known to be optimal. Since the s...

Cooperative communication achieves diversity through spatially separated cooperating nodes, which are battery powered in most applications. Therefore the energy consumption must be minimized without compromising the quality of service. In this context, we present a novel energy allocation scheme for multiple relay nodes that results in efficient cooperative multiple-input multiple-output (MIMO)...

The register allocation in loops is generally carried out after or during the software pipelining process. This is because doing the register allocation at first step without assuming a schedule lacks the information of interferences between values live ranges. The register allocator introduces extra false dependencies which reduces dramatically the original ILP (Instruction Level Parallelism)....

The Medium Access Control (MAC) of IEEE 802.11e defines a novel coordination function, namely, Hybrid Coordination Function (HCF), which allocates Transmission Opportunity (TXOP) to stations taking their QoS requirements into account. However, the reference TXOP allocation scheme of HCF Controlled Channel Access (HCCA), a contention-free channel access function of HCF, is only suitable for cons...

Combinatorial auctions have a wide range of real-world applications; yet, designing combinatorial auction mechanisms that simultaneously possess good economic properties and computational tractability remains a major challenge. An auction mechanism consists of an allocation rule and a payment rule. We propose a new framework that uses Structural SVMs to design a payment rule for any given alloc...

| In this paper, we study the problem of resource allocation and control for a network node with regulated traac. Both guaranteed lossless service and statistical service with small loss probability are considered. We investigate the relationship between source characteristics and the buuer/bandwidth trade-oo under both services. Our contributions are the following. For guaranteed lossless serv...

In this paper a unified approach for power allocation (PA) problem in multi-hop orthogonal frequency division multiplexing (OFDM) amplify-and-forward (AF) relaying systems has been developed. In the proposed approach, we consider short and long-term individual and total power constraints at the source and relays, and devise decentralized low complexity PA algorithms when wireless links are subj...
