Mobile, nomadic, and fixed wireless devices form new types of resourcesharing networks called wireless grids.1 This issue of IEEE Internet Computing, beginning with our extended editorial introduction, presents an overview of current research in the area. We hope this issue of IC will serve to map the wireless grid landscape, to help others explore it in greater detail in the future. Grid compu...

Conventional GRID service is static (no mobility), and it has many drawbacks such as continuous connection, waste of bandwidth, and service overloading. Wireless GRID supports mobility, however it should consider geographic position to support efficient resource sharing and routing. When the devices in the GRID are highly mobile, there will be much traffic to exchange the geographic position in...

the mobile node moves from one access point to another, the active connections will not be badly dropped if the handoff is smooth and if there are sufficient resources reserved in the target access point. In a 5x5 grid of access points, within a 6x6 grid of regions, by location tracking and data mining, we predict the mobility pattern of mobile node with good accuracy. The pre-scanning of mobil...

This paper wishes to investigate the converging field of mobile and Grid computing by defining an architecture for the provision of Grid services, which is based on standards, robust and useful across application domains. We propose using the mobile agent paradigm in order to develop a middleware layer that takes care of all the details to allow mobile users to access distributed resources in a...

This paper deals with a trajectory planning problem that we call the ‘highway problem’. It consists in planning a time-optimal trajectory for a mobile which is travelling in a structured workspace amidst moving obstacles and is subject to constraints on its velocity and acceleration. By structured workspace, we mean that there exists lanes characterized by one-dimensional curves along which the...

A mobile agent is a computer entity capable of reasoning, use the network infrastructure to run in another remote site, search and gather the results, cooperate with other sites and return to his home site after completing the assigned tasks. Mobile Agent based applications research activities are increased and are applied in a wide range domain areas : network management, electronic commerce, ...

Due to the inherent limitations in computational, storage, battery power and wireless communications capability, mobile devices have not yet been widely integrated into the Grid computing platforms. However, given that millions of laptops, PDAs and other portable devices remain unused most of the time, this huge repository of resources can be potentially utilized leading to what is called a mob...

A natural extension of the existing Grid technology is to integrate mobile and low-profile devices into it and accessing the Grid services in a pervasive manner. However, the existing middleware for Grid does not support mobility in the Grid nodes and are generally suitable only for the high-profile service providers and clients. This paper proposes architecture for accessing Grid services from...
