Service-Oriented Computing (SOC) is emerging as a paradigm for developing distributed applications. Centralized service discovery approach that uses UDDI registries that lead to bottleneck and vulnerability of failures problem. Distributed service discovery approach named chord that uses Dynamic Hash Table for service discovery that leads to less data availability. To address these problems an efficient service discovery approach called chord4S is introduced which provides efficient service discovery in peer to peer network environments .Data availability is improved by using this approach. In chord4S data availability is improved by distributing published descriptions of functionally equivalent services to different successor nodes.Chord4S provides better reliability and flexibility. By using this approach we can retrieve a list of matched service descriptions by forwarding queries. After retrieving a service we can open the location of the file and can access the specific folder with security. Also the accuracy of this process is also improved.
