A Hybrid Service Discovery Approach in Peer to peer Systems

  G Jahnavai Swetha,  G Senthil Kumar

Traditional Service Discovery methods are based on the centralized UDDI registries and can easily suffer from the problems of performance bottlenecks like single node failures, load balancing etc. To address these problems, many approaches based on distributed architecture have been proposed such as peer-to-peer-based decentralized service discovery approaches (CAN, Chord,Chord4S etc )which suffer from routing inefficiency and causes over head delays. Hence a new hybrid approach that is based on the decentralized peer to peer system as well as a centralized global repository is defined to address the problems. Based on the Chord 4S it supports service query with wildcards also. Load Balancing and Data Availability are further extended by distributing the domain specific services with respective peers and also a method called Request Mediator is introduced to reduce the overhead delay and improve the performance of the system.
