Energy saving and the protection of environment for sustainable society is now global agenda, that we must achieve for the next generation and for our Earth. This activity around IT and ICT industry is called as “Green IT/ICT”. Though the most of the Green IT/ICT would focus on the energy saving “of” IT/ICT equipments, we are focusing on the energy saving “by” IT/ICT technologies. The real targ...

Abstract: Over the last years, we have witnessed increasing interconnection between the physical and digital world. The so called Internet of Things (IoT) is becoming more and more a reality in application domains like manufacturing, mobile computing, transportation, and many others. However, despite promising huge potential, the application domain of smart homes is still at its infancy and lag...

In this paper the per-node throughput and end-to-end delay of randomly deployed (i.e. ad-hoc) hybrid radio frequency free space optics (RF/FSO) networks is studied. The hybrid RF/FSO network consists of an RF ad hoc network of n nodes, f(n) of them, termed ‘super nodes’, are equipped with an additional FSO transceiver with transmission range s(n). Every RF and FSO transceiver is able to transmi...

Some of the routing algorithms in mobile ad hoc networks use multiple paths simultaneously. These algorithms can attempt to find nodedisjoint paths to achieve higher fault tolerance capability. By using nodedisjoint paths, it is expected that the end-to-end delay in each path should be independent of each other. However, because of natural properties of wireless media and medium access mechanis...

The process of knowledge discovery in data (KDD) stored in computers in general requires iterations of three stages: data preparation, data mining, and results analysis. A variety of software tools are available for each of the stages. KDD environments, objectives of KDD, and types of data to be mined affect the choice of software tools in each stage. This article proposes a component-based arc...

Datacenters traffic is composed by numerous latency-sensitive “mice” flows, which is consisted of only several packets, and a few throughput-sensitive “elephant” flows, which occupy more than 80% of overall load. Generally, the short-lived “mice” flows induce transient congestion and the long-lived “elephant” flows cause persistent congestion. The network congestion is a major performance inhib...

We propose NEURAL ENQUIRER — a neural network architecture for answering natural language (NL) questions based on a knowledge base (KB) table. Unlike existing work on end-to-end training of semantic parsers [Pasupat and Liang, 2015; Neelakantan et al., 2015], NEURAL ENQUIRER is fully “neuralized”: it finds distributed representations of queries and KB tables, and executes queries through a seri...

The burstiness of variable bit rate traac makes it diicult to simultaneously make eecient use of network resources and provide end-to-end performance guarantees. In this paper, we present a smoothing scheme that allows network clients to optimize their quality-or price-of-service to respectively reduce their end-to-end delay bound or decrease their resource requirements from the network. Whethe...

FGS (Fine Granularity Scalability) is a scalable coding technique which can provide flexibility and good performance for Internet video streaming. However, FGS is not suitable for wireless video streaming. This is mainly because the low coding efficiency of FGS does not fit the limited bandwidth of wireless networks. In this paper, we jointly consider mode selection and UEP (unequal error prote...
