An Immune-Inspired Web Service Discovery Mechanism on P2P Network

The immune cells make fleeting contacts as they constantly roam the body seeking out signs of disease and exchanging information about present dangers. Inspired by this study, we design a web service discovery mechanism on unstructured P2P network. Every peer publishes their services on their local resource list. All the Web services are clustered into alliances according to functional properties. The query packets wander among these alliances to make rapid recognition. These packets exchange experience learned from the wandering when they encounter. A query packet will be proliferated in the alliance which most matches against the query. Each service in this alliance will be evaluated according to non-functional properties. Eventually, the best service is elected out for Web service integration. The results of our experiment showed that the experience and the exchanging had cut down the probing times obviously.
