Advances in high quality digital wireless networks and differentiated services have enabled the development of mobile multimedia applications that can execute in global infrastructures. In this paper, we introduce a novel approach to supporting mobile multimedia services by effectively exploiting the intermittently available idle computing, storage and communication resources in a Grid infrastr...

This paper looks into the possibility of using the regular traffic patterns provided by public buses to improve the performance of Mobile Ad-hoc Networks (MANET) for Inter-vehicular communications systems (IVCS). MANET is an adhoc network with mobile nodes that are random and unpredictable. IVCS provide drivers and passengers with a range of services, and implementation of IVCS is possible usin...

Recent advances in mobile and ubiquitous computing and wireless communications and networking have paved the way for a new learning paradigm called Mobile (e)Learning (or m-learning). Over the same period there has been an increasing interest in Semantic Web technologies and ServiceOriented Architectures such as Web Services and the Grid. In this paper we discuss the potential benefits and key ...

Mobile and wireless devices become more popular and their capabilities increase as well. At the same time, most of the today’s PC power is unused, as a study of the Gartner Group indicates. Grid computing and P2P systems take advantage of this fact and provide unused resources to other nodes within the network, but mobile scenarios or ad hoc networks are often left out. This paper presents a co...

Our research addresses how to integrate exploration and localization for mobile robots. A robot exploring and mapping an unknown environment needs to know its own location, but it may need a map in order to determine that location. In order to solve this problem, we have developed ARIEL, a mobile robot system that combines frontierbased exploration with continuous localization. ARIEL explores b...

LTE (Long-Term Evolution Network) is gaining momentum with its success in smart grids. Many time-critical applications can be hosted in mobile grids using LTE. High degrees of intermittent connectivity and disconnections are prevalent in a mobile grid. When a mobile node disconnects, the processes become orphans and require migration. This paper proposes a non-DHT based heap overlay to determin...

Jussi Ruutu, Nokia Research Center, Finland Jukka K. Nurminen, Aalto University, Finland *corresponding author Kari Rissanen, Helsinki Region Transport, Finland ABSTRACT Because of losses in electricity conversion and storage only part of the energy taken from the power grid produces useful work in a battery-operated mobile device; the rest evaporates as heat. We analyze the recharging activ...

to scattered radiation. This technology improves the quality of images taken without an anti-scatter grid at bedside or emergency radiography. Conventionally, grids are commonly used to reduce the influence of scattered radiation. However, due to the positioning difficulties, images are often acquired without a grid for mobile examinations, which results in images with low contrast. Virtual Gri...

Grid computing has emerged to cater the need of computing-on-demand (Jana et al., 2009) due to the advent of distributed computing with sophisticated load balancing, distributed data and concurrent computing power using clustered servers. The Grid enables resource sharing and dynamic allocation of computational resources, thus increasing access to distributed data, promoting operational flexibi...
