Fault tolerant Grid computing is of vital importance as the Grid and Mobile computing worlds converge to the Mobile Grid computing paradigm. We present an efficient scheme based on task replication, which utilizes the Weibull reliability function for the Grid resources so as to estimate the number of replicas that are going to be scheduled in order to guarantee a specific fault tolerance level ...

The performance of services implemented in the serviceoriented knowledge grid becomes one of the most key issues that affect the development of the knowledge grid. This paper presents a knowledge grid architecture based on mobile agent and effectively utilizes mobile agent's mobility, flexibility and intelligence to implement knowledge grid services. The idea that applies MA technologies to the...

Grid computing and pervasive computing have affirmed respectively as the paradigm for high performance computing and the paradigm for user-friendly computing. The conjunction of such paradigms are now generating a new one: the Pervasive Grid Computing. This paper presents a middleware for pervasive grid applications. It consists of a set of basic services that aim to enhance classic grid enviro...

Mobile devices, which are progressively surrounded in our everyday life, have created a new paradigm where they interconnect, interact and collaborate with each other. This network can be used for flexible and secure coordinated sharing. On the other hand Grid computing provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities. In this paper, effo...

We present a design of a Mobile Grid Resource Management System aimed at integrating mobile resources to an existing Grid infrastructure, while creating a platform for interoperability with telecommunications providers. In order to reduce the load on an existing infrastructure, we separate responsibilities and run additional features on mobile resources. Finally we present the Ikaros-EG impleme...

Today mobile phones are the most widespread devices in the world. The numbers of mobile phones today are, four times more than the number of PCs. This provides high potentials for providing some capabilities like data grid on mobile phones. Unfortunately, there is no suitable software system to provide this capability on mobile phones; however, we have enough hardware capabilities. All previous...

Navigation is a major challenge for autonomous, mobile robots. The problem can basically be divided into positioning and path planning. In this paper we present an approach which we call grid-based navigation. Though we also propose a scheme for path finding, we focus on positioning. Our approach uses minimal environmental infrastructure and only two light sensors on the mobile device itself. S...

To tackle with mobile robot path planning problem, we developed a novel path planning method utilized 3D grid map. Firstly we construct point cloud map using mobile robot equipped with 3D-LRF, then we transform point cloud into octree data structure, getting 3D grid map. We take mobile robots size and motion into consideration, develop a D* lite algorithm based path planning method which can ge...

A Wireless Grid is an augmentation of a wired grid that facilitates the exchange of information and the interaction between heterogeneous wireless devices. While similar to the wired grid in terms of its distributed nature, the requirement for standards and protocols, and the need for adequate Quality of Service; a Wireless Grid has to deal with the added complexities of the limited power of th...

The emerging Grid is extending the scope of resources to mobile devices and sensors that are connected through unreliable networks. Nowadays the number of mobile device users is increasing dramatically and the mobile devices provide various capabilities such as location awareness that are not normally incorporated in fixed Grid resources. Nevertheless, mobile devices exhibit inferior characteri...
