| Summary: | It is typical that in a multi-agent system there exist service requestor agents that search for suitable service provider agents to solve specific problems.In this environment, service discovery can be achieved with the use of a middle agent (MA) who provides matchmaking services.Multiple federated MAs can be employed and dynamically discovered to avoid bottleneck problem and single point of failure.In addition, a peer-to-peer (P2P)network can be utilized for a wider scope of discovery.In this paper, we propose a middle agent based super peer architecture (MESRA) for wide area service discovery.We explore scalable and efficient discovery through exploration which results in the formation of similar overlay networks and monitoring which caches service requests results.Simulation experiments show that MESRA provides better performance as compared to discovery through purely super peer (PSP) and Gnutella based overlay network. |
