One of the key enhancement elements of next generation LTE networks is the deployment of relays. Relays provide added performance gains in the form of enhanced coverage for mobile UEs situated in poor coverage areas. Relays provide coverage gains in high shadowing areas and also help reduce power consumption at the UE terminal by enabling a better communication channel. A striking aspect of relays...
In this paper, a PSO-DV (Particle Swarm Optimization with Differentially Perturbed Velocity) based approach to find optimal size, number and site of capacitor in radial distribution system is presented. The PSO-DV approach consists of classical Particle Swarm Optimization (PSO) and differential evolution approach in combination. For capacitor placement problem, the power losses occurring in the system...
This paper presents a novel Genetic Algorithm based exploration approach for integrated scheduling, allocation and binding in High Level Synthesis for Digital Media applications. The contributions of the proposed approach in this paper are: (a) Exploration of performance-hardware area tradeoffs of DSP digital media applications (b) Novel multi structure topology for chromosome encoding (c) Introduction...
This paper proposes an analytical framework for engineering a star wireless infrastructure for smart power grids based on OFDMA access technology (e.g., WiMax or LTE technology). The considered network model can represent the last-mile (i.e., local area networks) or high speed backhaul part of the power grid communications infrastructure. This proposed analytical framework would be useful in designing...
This paper deals with the sub-carrier and bit allocations for multi-user orthogonal frequency division multiplexing (OFDM) systems by a modified particle swarm optimization (MPSO) method for a specific bit error rate (BER). The resources (subcarriers and the number of bits per symbol per subcarrier) are allocated according to the instantaneous channel state information (CSI) which is assumed to be...
We address the problem of minimum average packet delay of Multi-hop Wireless Networks (MWN) which uses network coding. Our objective is to allocate capacities to different wireless nodes in a way that the average packet delay in the network is minimized under the assumption that the network topology, the traffic matrix in the network, and routing are given. Exploiting queueing theory as well as wireless...
Co-operative relay is emerging technique for 3G/4G high bandwidth networks in order to improve the capacity of edge nodes. As the deployment cost is high, there might be a few number of relay nodes in the cell which can help the edge nodes to transmit their data. From this perspective, one of the key problems for a relay node is to make decision which edge nodes to help and how much resource need...
