Internet computing and Grid technologies promise to change the way we tackle complex problems. Harnessing these new technologies effectively, it will transform scientific disciplines ranging from high-energy physics to life sciences. This paper describes a metropolitan-scale Grid computing platform named TIGER Project (standing for Taichung Integrating Grid Environment and Resource), which basically interconnects universities and high schools' cluster computing resources and sharing available resources among them, for investigations in system technologies and high performance applications. This novel project shows the viability of implementation of such project in a metropolitan city.

On wireless Grids Information Services have special requirements. Resource information has to be updated when users and resource providers arrive and depart frequently. Meanwhile, Information Services may be also mobile, so the clients and information sources should dynamically detect the existence and departure of Information Services. We present WGMDS, a WSRF-compliant and P2P (peer to peer) based Information Service to meet the special requirements on wireless Grids. We employ P2P mechanism to integrate Information Services to provide Grid-wide resource information. In WGMDS, the clients and information sources dynamically probe nearest Information Services to query or register resource information. Three algorithms are proposed to support the Information Service architecture. We use simulations in NS2 to evaluate the three algorithms.

Unstructured Peer-to-Peer networks support uncoupled data placements, elaborate semantic queries and highly dynamic scenario. These properties make such systems extraordinary suitable for applications of mass-market decentralized file sharing, which is still the most dominant application currently in use on current P2P-powered systems. In this paper, we propose SSplus, a novel search algorithm extended from our previously developed Smart Search algorithm, focusing on improving the search efficiency and the network utilization in unstructured P2P file-sharing systems, We achieve these goals by introducing several novel techniques below as enhancements: (a) Load Balancing based on Free Availability, (b) Intelligent 2-Level Replication, and (c) Resources Booking and Reservation. Extensive simulations under realistic conditions substantiate significant performance gains of SSplus, compared with the original Smart Search algorithm.

distributed virtual environments tend to become a de facto solution for large-scale networked virtual environments. One of the key issues and problems that need to be handled in the design of a scalable and effective distributed virtual environment system is the partitioning problem, which refers to the efficient assignment of the system's workload to the available resources of the system. This paper presents an object driven partitioning approach based on the partitioning algorithm of Lui & Chan, who proposed a three step technique for balancing the workload among the servers of the distributed Virtual Environment.

In recent years, wireless sensor networks have received great interest with rapid developments in both hardware and software aspects. However, there is always a problem with limited energy supply for the tiny sensor node. In wireless imaging sensor network in which imaging devices are utilized, the bottleneck of energy consumption efficiency is even more serious. The main activities of such imaging networks are related to image data transmission over wireless channel. Therefore it is necessary to seek a good balance between the image quality and energy conservation. We propose an energy-efficient control scheme based on recent dynamic range coding techniques. The simulation results are presented with emphasis on prolonging the sensor network lifetime.
