Hybrid Routing, Modulation, Spectrum and Core Allocation Based on Mapping Scheme

Threshold-based hybrid relay selection and power allocation scheme

To minimize total transmit power in a system while guaranteeing the outage probability at the same time in a cooperative system, we propose and analyse two threshold-based hybrid relay selection and power allocation schemes for a threenode cooperative relaying system. They are designated as: the hybrid amplify-direct-forward relaying (HADF) and incremental hybrid decode-direct-forward relaying ...

Decentralized Routing and Power Allocation in FDMA Wireless Networks based on H∞ Fuzzy Control Strategy

Simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. In this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of FDMA based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with Fuzzy distributed H∞ control strategy ....

Multicast Routing and Spectrum Allocation Algorithm Based on QOS Constraints Load Balancing in Wireless Network

To deal with the issues like existing generation of congestion nodes and redundancy transmission in the traditional load balancing algorithm, this paper puts forward the load balance multicast routing and spectrum allocation algorithm based on QOS constraints. The algorithm adopts LBWC algorithm to calculate the wireless link weight, and carries out the structure of the load balancing multicast...

Optimal Server Allocation and Frequency Modulation on Multi-Core Based Server Clusters

Multi-core processing has been widely used in high-performance computing systems. Power reduction and energy conservation are important in these systems to minimize operating cost. Two main strategies exist for power management: Dynamic Voltage/Frequency Scaling (DV/FS) and server number controlling: Vary-On Vary-Off (VOVF). In this paper, the authors explore the benefits of DV/FS and VOVF and ...
