Web services are new paradigm of using the Web. One of emerging challenges is to discover Web services efficiently and precisely. Unfortunately, existing systems like UDDI often have the problems of low availability, low accuracy, and bad performance. In this paper, we propose an approach of semantic Web services discovery in P2P environment. Firstly, Web services are published and deployed in same Web server to guarantee the availability. Secondly, Web servers are organized into groups to form a structured P2P network. Thirdly, for improving the query performance of service discovering, we propose a 2- layers searching algorithm. Finally we developed a prototype system, and tested the system in real P2P test bed of Planet-lab. Experimental results show our approach's precision, recall, query time and scalability. By analysis of the performance, we observed that the system has good efficiency and scalability.
