Cyber foraging is a pervasive computing technique where small, mobile devices offload resource intensive work to stronger, nearby surrogate computers in order to preserve energy and achieve better performance. The problem with relying only on local resources is, that the availability of such resources may be scarce in many environments. In this paper we therefore argue that a third tier should be...
Mobile devices with two network interfaces(WiFi and 3G) are already commercially available. Point-to-point communications such as Infrared and Bluetooth are also readily used. In the near future, mobile phones will have several interfaces including satellite and new technologies such as Ultra wideband. Hence we must assume that such devices will be multi-homed by default. For various reasons, including...
NFC technology can be integrated into existing systems to simplify and speed up the process of monitoring and control of these systems. In this paper we address a problem pertaining to the complexity of the monitoring and control of sensor or measurement equipment. Manual monitoring of measurement systems can be a tedious endeavor, especially in systems where the measurements are numerous and at regular...
Due to the resource limitations of mobile devices, it is difficult to run complex applications on the devices. To overcome the limitation, we adopt the concept of service-based mobile applications (SMAs) where some functionality is off loaded or provided as a service. Due to the complex nature of SMA architectures, it is challenging to design and implement efficient SMA. Hence, there is a demand for...
Over the past few years, multiplayer gaming experience has enhanced significantly and more developments are being done to improve the internet-based games. Even though many multiplayer games exist for the high-end mobile devices, majority of mobile phone users do not have access to them. Moreover, internet connectivity is not available in many places where a mobile phone network is present. This paper...
Nowadays internet-based banking is getting popularity because of its several advantages, such as ease of operation and virtual monetary activities, i.e., client's physical presence at different bank locations is no more required. However, because of scarcity of accessibility at different locations, cost, and slow speed, number of people using internet communication is a small percentage of the mobile...
This paper presents a system based on electronic equipments, standard mobile phones and WLAN networks for managing evacuation routes, or for obtaining information about victims' location and status, whenever a building collapses due to a disaster like earthquakes. The system is based on the standard Blue tooth specification to guarantee their application in indoor areas. The electronic equipments,...
This paper presents Byte-Map, which is a novel mobile map format for mobile map service in mobile devices. Byte-Map is a kind of vector format with different blocks through different levels, and map data of Byte-Map is encapsulated in binary stream. The basic cell of Byte-Map is a block, which is fixed in size of 255 units*255 units according to different coordinates systems and thus the coordinates...
This paper studies on a client / server wireless network model of hand-held mobile devices for land surveying and mapping industry, and accesses the credibility and methods of data communication between different programs through multi-threaded and socket. Key issues and technologies are discussed through practice, that wireless internet facilitate GIS data transfer, and multi-threaded applications...
This paper proposes a novel, nicknamed the "Pinpoint", method for an efficient and robust traffic estimation system using mobile phones as traffic probes. In this approach, the real-time traffic data is collected and sent to the server at the right time by the right players. Only the utilized data is reported to the server by the travelling vehicles. The mobile phones from walkers are prevented...
This paper proposes a novel method for detecting traffic congestions, qualifying and quantifying congestion levels using mobile phones as traffic probes. The system provides a robust mechanism for granularly comparing the seriousness of different congested areas. Congested areas are detected in a detailed manner by which exact congested positions are reported. Moreover, congestions can be detected...
A challenge in the convergence of heterogeneous networks is how to combine the ubiquitous resources and provide the diversified individual services. By this, the vision of adaptive and context-aware service provision becomes possible and offers new opportunities for pervasive computing. In this paper, we describe an approach that addresses the convergence of wireless personal area and wide area networks...
Nowadays, users of mobile phones generate too many files that have to be frequently downloaded to an external storage repository (freeing local space), using a USB cable or a short-range wireless connection such as Bluetooth. This situation is very common in developing countries where there are not many available wireless networks, restricting the user mobility. This paper presents an Internet File...
Mobile phone has become a powerful platform for people-centric computing. It is now a necessary part of everyday life for many people. A growing number of mobile computing applications are on the rise, centered around the user's daily life. In those emerging applications, location dependent systems have been identified as an important component. This paper presents the architecture and implementation...
Mobile devices are becoming more important in daily lives and they also have gained increasing acceptance in banking services, for example Short Messaging Service (SMS)-based m-banking system. In this particular system, an SMS receipt will be delivered to users for any transactions done. Though we could gain many benefits out of it, SMS is considered as informal receipt for banking services which...
Mobile phones with integrated digital cameras provide new ways to get access to digital information and services. Images taken by the mobile phone camera can be matched to a database of objects or scenes, which enables linking of digital information to the physical world. In this demonstration, we present a prototype system for image based linking of photos taken from pages of magazine. The system...
Contract-less wireless plans, in which customers are not locked into terms with providers, are becoming prevalent. The next step in this evolution is a contract-less competitive mobile wireless market in which a customer can, quite fluidly and seamlessly, choose to switch amongst wireless providers based on competitive terms at almost any time or place. This paper explores the concept and design of...
Authorization means using techniques to establish identity, based on the knowledge and information you know, have or are. A user name and a password is the knowledge people know, for example. Subscriber Identity Module (SIM) card in your mobile or a security ID card is what people have. Biometrics information, such as iris, fingerprint or face structure are what people are. The main theme of this...
Presence systems are widely used today to get information of user availability and their willingness to communicate. As presence and Unified Communications (UC) services are viewed as productivity enhancements within enterprises, the need to connect these services across enterprise WANs and MANs becomes more important. Adding to the availability to communicate is the growing use of mobile devices...
NFC is one of the latest wireless communication technologies, making possible variety of business opportunities. The current paper presents a generalized approach for NFC application development, where the Mobile Network Operators (MNOs), as well as service providers can make their own application and run it in the proposed common environment. We have developed the prototype of an application framework...
