In this paper we study the benefits of applying Software Defined Networking (SDN) to control forwarding in a network of constrained wireless edge devices. The proposed architecture is applicable to dense Small Cell deployments featuring wireless backhauling and edge computing capabilities, or to wirelessly connected sensor nodes following the fog computing paradigm. The paper introduces a novel path...
Human Machine Interface (HMI), referred to as a correlated system of human activities and operation of a specific device, ratifies control mechanism of a targeted machine by execution of certain physical actions. This paper presents an effective design of an Android-based Human Computer Interactive (HCI) system with voice command activation and gesture recognition to control a computer. With a continuous...
The AURORA Connected Vehicle Technology Testbed is currently being developed at the University of British Columbia with support from Transport Canada and the Asia-Pacific Gateway and Corridor Initiative and various other government and private sector organizations and in association with the ACTIVE Connected Vehicle Testbed at the University of Alberta. AURORA's mission is to provide Canadian researchers,...
The paper shows the design of an athlete performance measurement system for combat sports, which are still characterized by traditional training methods that give the athletes rules to reach effective shots, but without any objective measure. This work aims at a new instrumentation to measure the effectiveness of athletes' training, their moves, their shots, with lower cost than expensive devices...
Gas leakage accident occurs frequently due to the aging of pipeline and the third-party interference. To ensure safety during the gas pipeline emergency-repair, it's necessary to detect the gas concentration in the working place. In this paper, a WSN-based monitoring system for gas emergency repairing is proposed. The monitoring system is composed of the wireless nodes and the terminal software. The...
In this paper, we address the problem of ontology development by exploiting analogy between different but related knowledge domains. We define analogy model and use it in combination with question-answering approach for ontology development and validation processes. The proposed approach was practically evaluated in the use case of developing ontology for a wireless networking interface software module...
Nowadays new experimental studies in the area of wireless transcutaneous energy transfer and development of technical tools for these studies is actual. Hardware-software complex was developed that includes wireless energy transfer system, data acquisition system (NI ELVIS) and software part developed in LabVIEW software. Implementation of this complex allowed to significantly reduce time required...
Channel estimation is one of the vital processes in wireless communication systems. Assuming that A and B are two communication nodes, coefficients of the channel from A node to B node, must be very similar to the coefficients of the channel from B node to A node, due to channel reciprocity. In this paper, channel reciprocity property is tested by using software defined radio kits in laboratory environment...
Hardware and software equipment for the complex investigation of the wireless smart transducers used in the systems for controlling thermodynamic parameters of energy carries was developed on the basis of National Instruments equipment. Stand tests and qualify transducers by the parameters of radio channel and power supply simulating real conditions of exploitation. Software on the development environment...
Network Function Virtualization (NFV) is set to disrupt the current networking ecosystem by turning vertically-integrated middleboxes into software modules running on general purpose virtualized platforms. NFV will play a key role in future wireless and mobile networks where significant cost reductions can be obtained by virtualizing different layers and functions of the radio access and core network...
A Community Network (CN) is a bottom-up network infrastructure that interconnects communities of people and represents a promising and successful networking model. The more people join a CN, the higher is the demand for a wider range of community services and the need for scalable network protocols. CN designers and passionates hence require adequate frameworks to develop and test different technical...
The propagation of software viruses over a vehicular network where vehicles communicate via V2V links can have disastrous effects for the vehicles themselves and the ad hoc network. Here, we propose a simple distributed solution to block virus spreading over a VANET by initiating a negating spreading process that informs vehicles for the presence of infected nodes. We evaluate the proposed approach...
Vection is the illusion of self-motion, usually induced by a visual stimulus. It is important in virtual reality because inducing it in motion simulations can lead to improved experiences. We examine linear and circular vection in commodity level head-mounted displays. We compare the experience of circular vection induced through a real world stimulus, an optokinetic drum, with that experienced through...
Because of the recent advances in wireless technologies and, consequently the fast growing number of wireless devices that are being deployed in consumer houses, there is a growing demand from manufacturers to develop and deploy tools able to diagnose problems and evaluate the performance of their products prior to releasing them to the market. Such testing tools are required to be quickly deployable...
Pervasive health biomedical devices are presently trending towards supplementary usage with smart phones, tablets, and wearable gadgets to complement their ubiquitous roles in monitoring and diagnostic applications. In this paper, detailed design and development of a user-friendly mobile app using MIT App Inventor 2 software is explained, where emphasis is placed on building a graphical user interface...
The SmartCare project is to design, develop, and evaluate an intelligent sensor-driven living environment for the elderly. The core objectives are to provide emergency detection, improve quality of life, extend independence for the elderly, and detect patterns of behavior that could suggest early signs of a physical or cognitive issue, all in an unobtrusiveness manner. This paper specifically focuses...
The wireless sensor networks are highly dynamic in nature and their storage, processing and energy resources are limited. For these conditions routing protocols are required to maintain the network with reliable and secure communication. Lot of protocols are designed for routing but none of the protocol is proposed security as a main task. We advocate that Software Defined Network (SDN) enabled SPIN...
This paper introduces an optimal path finding problem for drone battery charging where their batteries should be charged for the travel from a source to a destination as needed. We present a practically reasonable heuristic to solve the problem by monitoring drones' battery status and traffic conditions in real time through a cloud-based service called traffic control center. This study will be the...
Software Defined Radio (SDR) or Software Radio is one of the most important technologies for the modern wireless communication system. SDR is a radio which can tune to any frequency band, implement different modulation and demodulation schemes and different standards in the same device by using reconfigurable hardware and powerful software. SDR provides flexible, upgradeable, multi-standard and longer...
Wireless access points are everywhere, at home, offices and public places like shopping malls, on the road and open spaces. Network engineer would require a specific tool to do wardriving, that is to search for Wi-Fi wireless networks by a person in a moving vehicle. The tool could be installed inside a portable computer, smartphone or personal digital assistant. Some hobbyist does wardriving to exploit...
