Abstract:Different coordination models exist for managing concurrency in complex distributed systems, for example,
direct interaction, tuple spaces, hierarchical structures, and publish-and-subscribe mechanisms. Online auctions
are complex distributed systems, where the choice of coordination model can significantly impact the
performance of multiple software agents, acting on behalf of human buyers and sellers. In this paper, we
evaluate analytically and experimentally different auction types and coordination models in an electronic
marketplace. Three important metrics are: the number of software agents, the number of messages exchanged
between these agents, and the number of migrations performed by the agents. We conclude that
dynamically choosing the number of agents and the coordination model can improve quality of service in
electronic commerce applications. Furthermore, in online auctions where there is a lot of interaction between
software agents, migration of agents to virtual stores and local bidding is more fair and efficient than using
remote interaction. This observation has the potential to significantly improve and redefine existing online
auction systems such as eBay.
