The increasing processing power and capabilities of mobile phones enable them to become the next generation of computing platform. Mobiles devices provide ubiquitous, inexpensive, and powerful computing resources that people could use wherever they are. The increasing availability of Web services and grid computing has made easier the access and reuse of different kinds of services. Web service...

In this paper we describe a distributed architecture that could be used to link emergency medical centres, hospitals, telephone operators, and ambulances into a hybrid Peer-to-Peer (P2P) and Grid system for the sharing of information and transport of data. Distributed computing techniques can be used to connect static and mobile systems, bringing the different tools, expertise and databases tog...

The use of wireless networking technologies has emerged over recent years in many application domains. The area of grids determines a potentially huge application domain, since the typical centralized computing centers require access from anywhere, e.g., from field engineers who are situated in a wireless network domain. Thus, the integration of suitable business views on mobile grids, of grid ...

In this paper, we compare two approaches for exploring large, hierarchical data spaces of social media data on mobile devices using facets. While the first approach arranges the facets in a 3x3 grid, the second approach makes use of a scrollable list of facets for exploring the data. We have conducted a between-group experiment of the two approaches with 24 subjects (20 male, 4 female) executin...

The emergence of small, mobile, inexpensive computing platforms has made computation possible virtually anywhere, and has opened up countless opportunities for distributed and decentralized collaboration and information sharing among a wide range of actors. The software-intensive systems of today are increasingly shaped by their decentralized, resourceconstrained, embedded, autonomic, and mobil...

The growing incidence of outsourcing and offshoring of professional applications is motivating increasing interest in the use of grid computing and grid topologies for meeting the infrastructure requirements. A Wireless Grid facilitates the exchange of information and the interaction between heterogeneous wireless and wired devices. Depending on the nature of the interactions among the constitu...

This paper examine that the geographic routing protocols are used in the mobile ad hoc networks. In routing protocols defines that each node identify the position of one hop neighbours, and also the packets are forwarded to a neighbours that is closer to the destination. This forwarding strategy should prevent radio communications between node. However, inexpensive position devices do not provi...

The driving environment is complex and dynamic, and the attention of the driver is continuously challenged, therefore computer based assistance achieved by processing image and sensor data may increase traffic safety. While active sensors and stereovision have the advantage of obtaining 3D data directly, monocular vision is easy to set up, and can benefit from the increasing computational power...
