With the exploration of the ocean, underwater acoustic communication has attracted more and more attention in recent years. The underwater acoustic channel is considered to be one of the most complicated channels because it suffers from more serious multipath effect, fewer available bandwidths and quite complex noise. Since the signals experience a serious distortion after being transmitted…

Modern applications for distributed publish/subscribe systems often require stream aggregation capabilities along with rich data filtering. When compared to other distributed systems, aggregation in pub/sub differentiates itself as a complex problem which involves dynamic dissemination paths that are difficult to predict and optimize for a priori, temporal fluctuations in publication rates, and the mixed presence…

Culture is the collective programming of the mind distinguishing members of one group or category of people from others [1]. Each culture is different. Therefore, there are five dimensions of culture and this article explains and explores one of these: Power Distance (PD). This paper will outline the impact of these dimensions in educational institutions.…

Proposed work shows the rain fade mitigation technique in wireless communication using linear prediction. Two year signal data from IPSTAR satellite at 20.2 GHz is used in this work. Proposed work can be used on different frequencies by using frequency scaling. Experimental signal is used to analyze original variations of the atmosphere. Delhi earth station data provided…

We are interested in understanding the neural correlates of attentional processes using first principles. Here we apply a recently developed first principles approach that uses transmitted information in bits per joule to quantify the energy efficiency of information transmission for an inter-spike-interval (ISI) code that can be modulated by means of the synchrony in the…

For implementing Cooperative Intelligent Transport Systems (C-ITS), Vehicle-to-X (V2X)communication functions are important. For efficient V2X simulation, integrating heterogeneous simulators and sophisticated inter-simulator network control are required. In this paper, we suggest Data Distribution Service (DDS) communication-based High Level Architecture (HLA) for distributed V2X simulation by replacing HLA network transport into DDS-based communication. For replacing, we design HLA-DDS wrapper…

In Software-Defined Network environment, operator can see the global view of network. So it can be manage flows with network-wide view, but legacy flow classification method cannot satisfy the integrated tables of all switches because of out of memory and long compilation time. So I proposed the architecture that can control network-wide flow classification to satisfy one’s policy like Quality-of-Service. The…

Through the information network recovery experience on the East Japan Great Earthquake on March 11, 2011, we learned that the combination of various existing wireless network technologies such as satellite IP network, 3G/LTE, Wi-Fi was useful in term of network connectivity. In this paper, by integrating those wireless networks into a cognitive wireless network, user can use this cognitivenetwork as an access network to Internet by selecting the…

5G communication networks enable the steering and control of Internet of Things and, therefore, require extremely low latency communications referred to as the tactile Internet. In this paper, we show that the massive use of network coding throughout the network significantly improves latency and reduces the frequency of packet re-transmission. Thus, an architecture built around network coding may be a feasible road towards…
