|This paper deals with a trajectory planning problem that we call thèhighway 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 ...

Problem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and it sh...

Decentralized control of mobile robotic sensor networks is a fundamental problem in robotics that has attracted intensive research in recent decades. Most of the existing works dealt with two-dimensional spaces. This report is concerned with the problem of decentralized self-deployment of mobile robotic sensor networks for coverage, search, and formation building in three-dimensional environmen...

Recently mobile devices become considered as grid resources as the technology of mobile devices and wireless communication network improves. But mobile devices have several problems such as instability of wireless communication, intermittent connection, limitation of power supply, and low communication bandwidth. These problems make it difficult to use mobile grid computing resources for stable...

UWAgents is a Java-based mobile agent system optimized for implementing grid computing infrastructure. Unlike most mobile agent systems, which are used only for job deployment and result collection in grid computing, UWAgents addresses specific requirements for coordinating the entire execution of a parallel and distributed computing application. These includes allocation of process identifiers...

This white paper provides a very short and high level overview of the IST Akogrimo project which is aiming at the provision of a framework for the provision of Grid based IT services in a commercial context including mobile devices, sensors and fixed resources enabling mobile collaborative business grid scenarios for the mobile citizen and worker. In this document a short classification of the ...

In a wireless sensor network (WSN), a large number of sensor nodes have to collect and forward data hop-by-hop to a sink. This paper presents an adaptive data collection (ADC) scheme with dynamic grid-length adjustments for mobile sinks in a grid-based WSN. In the proposed ADC, a mobile sink collects data along the Xand Y-axis of the grid. Due to simultaneous collections of multiple mobile sink...

In this paper we discuss our experience in evaluating the GridLab Mobile service as a tool which supports the combination of two mainstream research area, Grid computing and mobile devices. We use GridLab Mobile services platform to conduct our experiment to enable the access of Grid computing power from Poznan supercomputing and networking Center in Poland through smart phones. Minimum interfa...

This paper presents an Execution Management System (EMS) for Grid services that builds on the Open Grid Services Architecture (OGSA) while achieving “mobile awareness” by establishing a WS-Notification mechanism with mobile network session middleware. It builds heavily on the Session Initiation Protocol (SIP), used for managing sessions with mobile terminals (such as laptops and PDAs) where the...

Mobile Ad Hoc Grid deals with the challenges in resource discovery and job scheduling due to its mobility and power consumption. In this paper a new grid computing technique is implemented to manage the congestion control with job scheduling. The proposed addition of the mobile ad hoc network with in AHGL can offer maximum network utility. The model is implemented in the NS-2 network simulator.
