Fifth generation (5G) wireless networks will target at energy and spectrum efficient solutions to cope with the increasing demands in capacity and energy efficiency. To achieve this joint goal, dense networks of small cells (SCs) are expected to overlay the existing macro cells. In parallel, for the SC connection to the core network, a promising solution lies in a mesh network of high capacity millimeter...
The transfer of big data in various applications across high-performance networks (HPNs) in a national or international scope consumes a significant amount of energy on a daily basis. However, most existing bandwidth scheduling algorithms only consider traditional objectives, such as data transfer time minimization, and very limited efforts have been devoted to energy efficiency in HPNs. In this paper,...
Energy saving in the ICT equipments has been an urgent problem recently. Although the average utilization of network is less than 40% most of the time, its energy consumption is almost the same as peak-hour's. In order to minimize energy consumption and improve resource utilization, we aggregate traffic into a network subset and turn off the remaining network elements. The problem is the classical...
The De Bruijn topology, due to its interesting features such as a small minimal path, a small average latency and a small average number of hops, is a promising alternative topology to mesh-based NoCs for low-power applications. However, these advantages strongly depend on the efficiency of the routing algorithm in presence of congestion. This paper investigates efficient implementations of routing...
In this paper, we present a minimum-path mapping algorithm based on genetic algorithm that automatically maps IP cores onto 2D mesh network on chip (NoC) architecture. Our algorithm consists of node mapping and minimum routing paths selection. These steps map core communication graphs onto 2D mesh NoC architectures for optimizing communication power consumption and balancing the traffic across the...
