Sunway TaihuLight system is the first supercomputer offering a peak performance over 100 PFlops, which can be utilized to parallelize Non-dominated Sorting Genetic Algorithm II (NSGA-II), standard approach multi-objective optimization. However, insufficient off-chip memory bandwidth and limited scratchpad capacity of hinder improvement parallellizing NSGA-II. In this article, we propose an optimized parallel NSGA-II on system, called swNSGA-II, by utilizing process- thread-level parallelism...

The decomposition-based multi-objective evolutionary algorithm (MOEA/D) has shown remarkable effectiveness in solving problems (MOPs). In this paper, we integrate the quantum-behaved particle swarm optimization (QPSO) with MOEA/D framework order to make QPSO be able solve MOPs effectively, advantage of being fully used. We also employ a diversity controlling mechanism avoid premature convergence especially at later stage search process, and thus further improve performance our proposed...

With the emergence of adaptive bit rate (ABR) streaming technology, video/content technology is shifting toward a file-based content distribution. That is, video encoded into set smaller media files containing 2–10 seconds before transmission. This distribution, coupled with increasingly rapid adoption smartphones, requires an efficient distribution algorithm to satisfy QoS demand in wireless networks. In this paper, we study transmission finite-sized file over networks using multipath...

A future satellite communications system is envisioned that will provide a number of enhancements over predecessor communication systems. It employ high capacity packet switched service in space, rate circuits between terminals, and utilize Dynamic Bandwidth Resource Allocation which dynamically assigns resources to terminals based on current channel conditions traffic demand. However, realize these potential benefits, we must be able integrate the network seamlessly with existing networks....

Network connectivity is an important factor of the performance wireless Ad hoc networks (WANETs) because it represents lifetime that a node connected to arbitrary one. However, due dynamic networks, unstable. Under WANETs, influences are investigated. Although various models have been proposed study issues, comparisons under different channels fading lacking. In order compare impacts between channels, we calculate isolation probability and whole network whether can be Nakagamim Rayleigh two...

A butterfly network is a classical model to demonstrate the throughput advantage of coding technique over wireline networks.

This paper explores the problem of how a secondary transmitter could serve several users simultaneously by utilizing spectrum primary system while imposing no impact on it (i.e. satisfying coexistence constraint), even if keeps active all time. The difficulty this lies in that should tackle interference encountered at multiple receivers. In cognitive transmission framework, core above include two aspects: 1) How to learn quickly message(s) system? 2) efficiently address receivers with...
