Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to develop several simple DGM models with increased realism. Connectivity is a fundamental requirement for communication between nodes. In this paper, we investigate the connectivity in two basic DGM models in comparison with the widely used random waypoint (RWP) model. Specifically, first we expand the DGM models development and analysis software tool to include connectivity analysis. Second, we provide the experimental evaluation of connectivity in the two basic DGM models in comparison with RWP model. Finally, through NS2 simulation, we study the performance impact of these mobility models on the Ad-hoc On-demand Distance Vector (AODV) routing protocol - one of the most popular routing protocols for MANET.

Recently, an extended Wang's kWTA network with stochastic output nodes has been studied. It is shown that this extended model converges asymptotically. In this paper, we further studies the convergence time of this model. The convergence time is defined as the time taken for the model to reach a finite region around the convergent. With this definition, an approximation of convergence time is derived and its viability is shown by simulation results.

In this paper, we describe a mobile application that synchronizes the playback of a video stream among a group of mobile devices while the video playback is controlled (e.g. pause, resume, seek) by one of the devices. This feature allows a group of people to collaborate remotely in real-time through watching the same video on their mobile devices. To make this application work for heterogeneous mobile devices and networks, we develop synchronization protocols and time-based video position prediction algorithms on top of a REST platform that is independent of programming languages, operating systems and transport protocols. A prototype system has been developed based on Android phones connected by 3G cellular network. The preliminary experiments show the approach is feasible and promising.

The Semantic Web aims to enrich the existing Web by building an infrastructure layer of a web of data. Three-quarters of the data on the Web come from relational databases. Thus, in the context of the Semantic Web, it has become one of the most important topics to generate OWL ontologies from the legacy databases. For this purpose, the existing approaches typically define how to map the databases to the ontologies. However, the mappings are designed to work under highly normalized database schemas and to be carried out through a batch process of dumping database contents to the ontology repository for ontology population. The approaches can't contribute usefully to the proliferation of ontologies. In this paper, we propose a new set of mapping rules based on a view-based approach, which enables ontologies to be served even without their population through the massive dump process in advance. Consequently, the ontologies out of our approach can play as the complete OWL-described view on the database because they explicitly represent the semantics of relational model objects and operations. Compared with existing approaches, our approach is applicable to a wider range of database schemas, and besides it is designed to extract more meaningful relationships between entities by reasoning.

Recently, the requirement of database encryption has increased. But many companies are not willing to adopt the use of encryption in their existing DBs due to the degradation in performance. In this paper, we proposed and implemented a high speed database encryption model using Graphics Processing Units(GPU) that can perform parallel data processing. As a result, there was a performance improvement of about 40% to 60% compared to the CPU case. We expect our paper can be used to increase the encryption performance of database.

This paper presents the design, optimization and performance evaluation of artificial neural network for the efficient classification of Electromyography (EMG) signals. The EMG signals are collected for different types of volunteer hand motion which are processed to extract some predefined features as inputs to the neural network. The time and time-frequency based extracted feature sets are used to train the neural network. A back-propagation neural network with Levenberg-Marquardt training algorithm has been employed for the classification of EMG signals. The results show that the designed and optimized network able to classify single channel EMG signals with an average success rate of 88.4%.

Radio Frequency IDentification (RFID) is a wireless technology that promises to facilitate many identification and tracking solutions. The placement problem, i.e. choosing the optimal locations for RFID readers, tags or both in a given RFID layout, is reviewed in this paper. Placement approaches are generally coverage-driven and vary according to the system's scopes and constraints. RFID coverage is associated with readers' interference, which requires applying redundancy elimination algorithms. In this paper, we propose a coverage-based categorization of RFID placement schemes based on the span of the readers' field. We also provide a comparative analysis of placement schemes based on their performance objectives, constraints, and potential applications. We finally discuss some open issues regarding RFID placement in terms of alternative objectives and systems' specifications.

A novel idea presented in this paper is to deploy the Open Flow technology in wireless sensor networks that can lead to a significant achievement in Internet of things and cloud computing arena through network virtualization. Two new abstract layers namely Common platform layer and virtualization layer can be added at the top and bottom of a preset Infrastructure as a Service architecture. Our proposed IOT virtualization can be applicable in a random topology scenario which makes possible of the flow-sensors' resources to be shared, establishment of multi operational sensor networks and escalation of the reach ability under the same platform without establishing any further physical networks. Flow-sensor achieved 39% more reach ability than the typical sensors in an ideal scenario and even better results are possible from the amount of packets generation and simulation time viewpoint for larger scale networks.
