Recent developments in both hardware and software technology have provided the basis for a new distributed computing paradigm ? mobile computing. This paper presents a formal framework for modeling and analyzing mobile systems. The framework comprises a collection of models of the dominant design paradigms which are readily extended to incorporate details of particular technologies, i.e., programming languages and their run-time support, and applications. The modeling language is Object-Z, an
Mobile device integration in grid environments is a challenge for many researchers. Due to the transient nature of mobile devices, service management is a critical, but often overlooked area of research. The authors in this white paper propose a distributed broker responsible for the autonomic management of grid services. The broker provides self discovery and negotiation; self configuration and self healing for SOA based mobile grids. In this white paper the design and prototype implementation
Wireless Mesh Networks (WMNs) are self-organizing and self-configuring wireless networks, typically implemented with IEEE 802.11 hardware. In conventional wireless LANs, clients communicate with access points via a single-hop wireless link and access points are interconnected via a wired backbone infrastructure. This paper from Australian Computer Society propose simple extensions to the Ad-hoc On-demand Distance Vector (AODV) routing protocol, which aim to take advantage of the heterogeneity in
This paper describes about clicki: a framework for light-weight web-based visual applications. Web application frameworks typically provide little support for graphical web applications such as diagram editors. This restricts applications developed using these frameworks to either very limited interactions, or using technologies that are only supported by a small subset of web browsers. Clicki is an object-oriented web application framework in the style of traditional graphical user interface
Bioinformatics is an important application area for grid computing. The requirements for bioinformatics tools to access highperformance computing (HPC) resources are different from tools in other areas of research. This paper describes a Web Service based system called Grendel. Grendel acts as a single access point to HPC and is used to explore gridenablement issues for bioinformatics tools. It uses a language and platform independent mechanism for remotely interacting with the HPC environment.
With the globalization caused by the growth of the internet, companies face increasing competition from all over the world. Prices have reduced and competing products from vendors have tended to be very similar and having the same capability. Therefore, without product differentiation across companies, the costs to acquire and retain customers have increased as customers do not care as much about slight price differences. With a click of the mouse they can easily shift to another provider, and
