Towards load balancing in peer-to-peer environment of web services

With the development of Web services, more and more applications based on Web services are emerging on the web. Given the highly dynamic and distributed nature of Web services, implementing Web services in Peer-to-Peer (P2P) network is recently becoming increasingly popular. Our goals are to balance the loads among all the nodes through the management of services and resources in the P2P Web services system so as to ensure the efficiency of service execution. In this paper, we describe the solutions to the load balancing problem. First, we propose an architecture to organize the nodes in such systems. Then, we formally define the problems of load balancing and develop algorithms to them. Finally, we perform a series of experiments to verify our approaches. The experimental results show that our algorithms are effective to achieve the load balancing goals.
