Indoor positioning system (IPS) allows an object to be located and tracked within an indoor environment. With the introduction of Internet of Things (IoT), the business interest in location-based application and services has also increased. Hence, the demand for accurate indoor localization services has become important. Until now, researches related to IPS are still being conducted with the objective...
In this paper we formulate Network Coding (NC) and Analog Network Coding (ANC) using analytical models to quantify ANC performance parameters. For this reason, a chain topology in a non-mutual transmission was investigated. Our formulations demonstrate the benefit of NC and ANC over traditional approaches which depend on the number of transmission packets and the number of timeslots required for packets...
This paper presents a hardware implementation of the PRINCE block cipher in Field Programmable Gate Array (FPGA). In many security applications, the software implementations of cryptographic algorithms are slow and inefficient. In order to solve the problems, a new FPGA architecture was proposed to speed up the performance and flexibility of PRINCE algorithm. The concurrent computing design allows...
Many power utility companies around the world are moving towards smart grid, which integrates power delivery infrastructure with information and communication technologies. Smart meter is one of the main components of smart grid. The task of a smart meter is to track energy consumption of a premise and send that information to the utility company. Although the use of smart meter has many benefits,...
Stress problems often causes negative emotional response which tends to lead to a negative work performance. There are many treatments for stress such as going to gymnasium, undergoing hypnosis and taking medicine. Lately, virtual reality therapy (VRT) has been proposed as an alternative technique for stress treatment. In this VR-based treatment, one of the important elements to ensure its effectiveness...
This paper shares an author's findings on the effectiveness between guided and non-guided virtual reality setups during stress treatment. In the first setup, users are guided so that their virtual navigations are automatically controlled by a computer. On the other hand, in the second setup, users are allowed to move freely within a pre-set boundary. Findings obtained from this study, will be used...
This paper share in details the experiences gained during the development of a Virtual Reality application for a stress treatment. Throughout the twelve months development period, authors have faced numerous challenges and difficulties. Those challenges are encountered while setting up an open source game development platform called Cryengine and while integrating this engine with VR gadgets such...
Stress is a response that often make patients become un-stabled physically and mentally. Until recently, various types of treatment are practiced by physiologists to remedy stress problems. Virtual reality (VR) technology that is able to create an immersive 3D environment can be a better treatment therapy in comparison to existing techniques particularly to an imaginary technique. In this paper, we...
The Opportunistic Routing (OR) protocol provides an alternative and efficient method for exploiting the spatial and temporal characteristics of wireless networks. In addition to prioritisation and selection of relay nodes, another important aspects of the OR protocol is its ability to coordinate between potential relays node. A common approach for coordination is based on a mechanism known as the...
For ad-hoc wireless sensor networks (WSN), multi-hop routing has been adopted in order to save communication power consumption and to increase network lifetimes. In contrast to traditional multi-hop routing, the Opportunistic Routing (OR) protocol provides an alternative and efficient method for exploiting the spatial and temporal characteristics of wireless networks. One of the more important aspects...
In a resource constrained wireless sensor network (WSN), communication tasks can be expensive in terms of power consumption. Thus, when good communication is required, a mechanism that can maximize the chances of a successful transmission of information via wireless network is very desirable. The Opportunistic Routing (OR) protocol has been proposed as an alternative and efficient method for exploiting...
