A model of Web service discovery based on BalanceChord
Abstract
The research of Web service discovery can be distinguished into two layers: service discovery model and service discovery algorithm. In this paper a kind of services discovery model named WSDBC (Web Service Discovery based on BalanceChord) is proposed in order to extend the Web services discovery scope and improve discovery efficiency. In order to achieve load balancing between different nodes in WSDBC model, node join-in algorithm and self-balancing algorithm are proposed. When a new node joins in the BalanceChord, it must get the network load information and set its identifier in order to share the load of overloaded node. By the self-balancing algorithm a node would periodically compare its load with its neighbors and share its load clockwise. A simulative system ChordSim is designed and implemented. Experimental results show this model and algorithms have a good performance.
