Abstract— Since the beginning of the service oriented paradigm, the Web service discovery presents an important problem. Web Services should act autonomously with as minimal human intervention as possible, they should be able to discover other services which have particular capabilities and realize precise tasks. To improve the automatic discovery of Web services, other technologies are used to provide new flexible solutions for web services discovery and composition. In this context, the Web semantic and the Peer-to-Peer (P2P) computing present the most adapted technologies to the service-oriented approach. We present a distributed solution based on epidemic algorithms to discover semantic Web services in unstructured P2P networks. In this solution, we use a distributed table to preserve the description and the composition way of the P2P composed Web services. We improve this choice by adding other algorithms that ensure the data coherency of this table. Also, we present a distributed architecture for which implements this solution. A motivate example is presented in this paper to improve the proposed model.
