This paper proposes a semantic overlay based on the small world phenomenon that facilitates efficient search for information retrieval in unstructured P2P systems. In the semantic overlay, each node maintains a number of short-range links which are semantically similar to each other, together with a small collection of long-range links that help increasing recall rate of information retrieval and reduce network traffic as well. Experimental results show that our model can improve performance by 150% compared to Gnutella and by up to 60% compared to the Interest-based model - a similar shortcut-based search technique.
The emerging grids need an efficient replica location mechanism. In the experience of developing Chinagrid Supporting Platform (CGSP), a grid middleware that builds a uniform platform supporting multiple grid-based ap...

This paper presents ALTER, an adaptive failure detection service, which incorporates the technique of unreliable failure detection service and the idea of R-GMA. ALTER is organized in a hierarchical structure and it can be adaptive to the system conditions and user requirements with changing the system parameters and system organizations. With mathematical evaluation, ALTER shows good scalability and flexibility, which is suitable for grid environments. Copyright 2006 ACM.
grid information service influences quality of service for grid platforms directly. In this paper, based on network latency, network coordinate is introduced into grid information service to locate each grid node. By ...
