The limitations of client-server systems become evident in the large scale distributed environments. Peer-To-Peer (P2P) networks can be used for improving communication process, optimizing resources discovery/localization, facilitating distributed information exchange. P2P applications need to discover and locate efficiently the node that provides the requested and targeted service. This paper proposes an approach called Chord4S, a Chord-based decentralized service discovery approach that supports service description distribution and discovery in a P2P manner. The main aim of designing Chord4S approach is to largely improve the availability of service descriptions in volatile environments by distributing descriptions of functionally equivalent services to different successor nodes.
