With the consideration of scalability and robustness, distributed computing systems such as grids and clouds may exploit the P2P approach to enhance their performance. However, conventional techniques in P2P systems cannot be applied directly into grid systems due to restricted sort of queries for desired resources. In this paper, we consider a fully decentralized resource discovery service based on an unstructured overlay, where the major challenge is to locate desired resources without the global knowledge about sharing resource information. Consequently, more nodes involved in the resource discovery scheme may incur higher network overhead. To achieve an efficient resource discovery, this paper aims to alleviate the network traffic among unstructured information systems. Relying on the information of resource attributes and characteristics, we propose the direction-aware resource discovery scheme to improve the overall performance. Experimental results illustrate that the proposed approach is efficient and scalable compared with conventional approaches.
