As data management applications grow more complex, they may need efficient distributed query processing, but also subscription management, data archival etc. To enact such applications, the current solution consists of stacking several systems together. the juxtaposition of different computing models prevents reasoning on the application as a whole, and wastes important opportunities to improve performance. We present a simple extension to the AXML [7] language, allowing it to declaratively specify and deploy complex applications based solely on XML and XML queries. Our main contribution is a full algebraic model for complex distributed AXML computations. While very expressive, the model is conceptually uniform, and enables numerous powerful optimizations across a distributed complex process.(1)

Grid computing architecture was defined to be a complete physical layer. the functions of information systems based on grid architecture are resources sharing, collaborative processing, etc. Resources are used by processes. System performance is calculated from resources usages. Process scheduling is more important when jobs are not uniformly distributed in all grid nodes. In this paper, we proposed a process schedule analyzing model based on grid computing architecture. this model can make all grid nodes be loading-balance. When the load of the node is heavy, it can select the other grid nodes to execute its job by the verification of supervisor grid node and then the job is transferred. Via implementing this model, we can have the best system performance.
As the large volume of resources involved and the power of computational Grids increased, there is a corresponding and urgent need for employ the grid technologies into problem solving environment (PSE) domain in orde...

Delegates and friends, we are very pleased to extend to you the sincerest of welcomes to this, the 10thinternationalconference on Knowledge Based and Intelligent Information and Engineering Systems at the Bournemouthinternational Centre in Bournemouth, UK, brought to you by KES international. this is a special KES conference, as it is the 10th in the series, and as such, it represents an occasion for celebration and an opportunity for reflection. the first KES conference was held in 1997 and was organised by the KES conference founder, Lakhmi Jain. In 1997, 1998 and 1999 the KES conferences were held in Adelaide, Australia. In 2000 the conference moved out of Australia to be held in Brighton, UK; in 2001 it was in Osaka, Japan; in 2002, Crema near Milan, Italy; in 2003, Oxford, UK; in 2004, Wellington, New Zealand; and in 2005, Melbourne, Australia. the next two conferences are planned to be in Italy and Croatia. Delegate numbers have grown from about 100 in 1997, to a regular figure in excess of 500. the conference attracts delegates from many different countries, in Europe, Australasia, the Pacific Rim, Asia and the Americas, and may truly be said to be ‘international’. Formed in 2001, KES international has developed into a worldwide organisation that provides a professional community for researchers in the discipline of knowledge-based and intelligent engineering and information systems, and through this, opportunities for publication, networking and interaction.

Ad hoc networks consist of wireless hosts that communicate with each other in the absence of a fixed infrastructure. Such networks cannot rely on centralized and organized network management. the clustering problem consists in partitioning network nodes into groups called clusters, giving a hierarchical organization of the network. A self-stabilizing algorithm, regardless of the initial system configuration, converges to legitimates configurations without external intervention. Due to this property, self-stabilizing algorithms tolerate transient faults. In this paper we present a robust self-stabilizing clustering algorithm for ad hoc network. the robustness property guarantees that, starting from an arbitrary configuration, in one round, network is partitioned into clusters. After that, the network stays partitioned during the convergence phase toward a legitimate configuration where the clusters partition ensures that any neighborhood has at most k clusterheads (k is a given parameter).

In this paper, an optimized LKH scheme based on one-way hash function for secure group communications is proposed. the proposed scheme uses the one-way hash function to compute all the keys in the key tree. And it marks the key tree using node coordinates so that the coordinates of nodes on path of the member node location can be easily obtained and the keys required updating can be easily known when a member joins or leaves. It is suitable for the large-scale dynamic secure multicast group. the computation amount, key distribution amount and other performances of this scheme are analyzed in this paper. Compared withthe traditional LKH scheme, it greatly reduces key storage amount, key distribution amount, key computation and communication amount of group manager required by a join/leave request. And compared with other improved schemes, it greatly reduces key storage amount of group manager.

Grid computing is a computing framework to meet the growing computational demands. this paper introduces a novel approach based on Particle Swarm Optimization (PSO) for scheduling jobs on computational grids. the representations of the position and velocity of the particles in the conventional PSO is extended from the real vectors to fuzzy matrices. the proposed approach is to dynamically generate an optimal schedule so as to complete the tasks within a minimum period of time as well as utilizing the resources in an efficient way. We evaluate the performance of the proposed PSO algorithm with Genetic Algorithm (GA) and Simulated Annealing (SA) approaches.
