SODP: A New Paradigm for Mobile Grid

Journal of Industrial and Intelligent Information, 2014

This paper presents a distributed object transportation technique using a virtual object. Previous methods of object transportation have been required to have a global navigation function with a feedback controller. In other words, all robots should have the goal position to manipulate the object when using those methods, and with them it was difficult to guarantee the wrapping condition of the object during transportation. The proposed technique, however, enables the object to be transported without a global navigation function by means of a new technique termed a virtual object. The proposed technique is divided into three phases: the approaching phase, the enclosing phase, and the transporting phase. Simulated experiments are presented to test the validity and practicality of the proposed method.  Index Terms-object transportation, virtual object, object closure This paper presents a distributed arbitrary-shaped object transportation technique using a virtual object. The virtual object represents the position of the object at the next time step. Multiple robots manipulate the object

The paper deals with a problem of low data throughput on wirelessly connected mobile devices and a possibility to solve this problem by prebuffering of selected artefacts. The basics are in determining the problem parts of a mobile device and solve the problem by a model of data prebuffering-based system enhancement for locating and tracking users inside the buildings. The framework uses a WiFi network infrastructure to allow the mobile device determine its indoor position. User location is used for data prebuffering and for pushing information from a server to PDAs. All server data are saved as artefacts with its indoor position information. Accessing prebuffered data on a mobile device can significantly improve a response time needed to view large multimedia data. The solution was tested on a facility management information system built on purpose with a testing collection of about hundred large size artefacts.

The Distributed object computing is a paradigm that allows objects to be distributed across a heterogeneous network, and allows each of the components to interoperate as a unified whole. A new generation of distributed applications, such as telemedicine and e-commerce applications, are being deployed in heterogeneous and ubiquitous computing environments. The objective of this paper is to explore an applicability of a component based services in ubiquitous computational environment. While the fundamental structure of various distributed object components is similar, there are differences that can profoundly impact an application developer or the administrator of a distributed simulation exercise and to implement in Ubiquitous Computing Environment.

Mobile technologies and devices are being upgraded at an enormous speed. The market offers a variety of mobile devices and a number of different technologies. At this moment, wireless communication technology is one of the most popular and important communications in mobile technologies area. However, the growth of this technology not fully utilized as a mobile robot controller. The field of robotics includes various sectors such as factory sector, manufacturing and security. These papers describe research and investigation on mobile robot controller via mobile technologies. The most important in this paper is to compare the data transferring technique for mobile robot controller. Among the techniques in this study were Data Oriented Transfer Service (DOT), Distributed Parallel Storage System (DPSS), GridFTP and Black-Bus. For future work, we propose the development of mobile robot controller via mobile technology which is 3G technology. The results of this research are expected to provide benefits to consumers and mobile device manufacturers to optimize the usability of mobile devices.

The increase in the popularity of small digital mobile devices also implies an increased demand in applications. The limited computing capabilities on the mobile devices and the unreliability of wireless links are barriers to the smooth access of mobile devices to the Grid applications and resources. In this paper a proxy-based approach is presented that is able to support various kinds of applications to be used by mobile devices by providing specific-purpose services on the proxy. The implemented prototype that includes some of the realized proxy services and the example client application for a mobile device show the viability of the proposed approach.

Parallel computing methods decrease the processing time in mobile distributed systems compared to the conventional sequential computing techniques. But as they are developed from smaller mobile clusters to extensive mobile grids, they are prone to issues like high latency/jitter, processing speed, communication overhead, and low data transfer rate. So, an efficient and optimized parallel computing paradigm known as Distributed Shared Proxy Object Model (DSPOM) is developed based on Surrogate Object Model (SOM) integrated with Distributed Shared Object (DSO) for mobile grid. SOM is chosen to enhance the resource sharing of mobile grid computing, while DSO is chosen to reduce the computational complexity. The unused computing determinant is utilized by SOM to save the processing time. The transparency of the DSO model in terms of distribution and heterogeneity reduces the computational complexity. DSO also enhances the load adaptability and fault-tolerance to parallel programs on the mobile grid. The DSPO model performs better in terms of query time, query latency, packet loss, load adaptability, and fault-tolerance.

Real world objects are recognized by tracking less and tracking based techniques. Mobile augmented reality browsers are tracking less systems, which acquires location data using global positioning system and provide information in the form of maps or web links. Tracking based techniques recognize objects through markers or directly real world objects without markers. Marker based systems actually track the markers not the real objects and therefore, these approaches hides the reality. Markerless (direct real object tracking) systems use client-server architecture. However, these are affected by network latency. The Smartphone is capable to recognize and track real world objects without any server and marker. It can guide the users about their location and also provide information in a convenient way. Therefore, an improved algorithm for tracking real world objects through natural features was formulated. The modified version of speed up robust features (SURF) was used for features f f extraction from live mobile camera image and recognition. The pose matrix from extracted features was calculated by Homography. The adapted algorithm was tested in a mobile AR-prototype application using iPhone. It was found from the results that the formulated algorithm recognized and tracked the real world objects from natural features in speedy, easy and convenient way

In this paper, we discuss on the extension of grid computing systems in mobile computing environments, where mobile devices can be effectively incorporated into the grid either as service recipients or as more valuable service providers. First, based on the present grid architecture, we try to figure out what would be the newly required services in such a mobile/grid integrated architecture.
