Requirement for high bandwidth internet traffic is growing rapidly now-a-days. Utilization of the available resources becomes troublesome due to rise in the number of users. So it is important to provide the resources efficiently. To solve the problem of resource provisioning, many developments have been made by the researchers. During working hours, the scheduled traffic is huge and sluggish during...
Nowadays, SoC uses Network on Chip (NoC) to connect its increasing number of building blocks. FPGAs, like SoCs, can use NoC to connect its increasing number of tiles, memories, DSP slices and embedded processors. But one drawback of using NoC is that increasing its router ports will affect the area, power and frequency of the system significantly. For FPGAs to benefit from the NoC approach we have...
In this paper, we propose a three-stage reconfigurable topology synthesis approach for Application-Specific NoC (ASNoC) on partially dynamically reconfigurable FPGAs, where the topology is reconfigured dynamically at run-time along with the application’s execution. Firstly, given the scheduling and floorplanning of task modules, an Integral Linear Programming (ILP)-based method is proposed to partition...
In this paper, two hybrid multi-hop/single-hop opportunistic transmission strategies for lifetime extension of WSNs are proposed. To prolong the network lifetime, a systematic model that contains a network distribution block, a routing algorithm block, a traffic pattern block and an optimal policy block is presented to determine the optimal transmission probability of each node. With the global routing...
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...
