Agents are a useful abstraction frequently employed as a basic building block in modeling service, information and resource sharing in global environments. The connecting of requester with provider agents requires the use of specialized agents known as middle-agents. In this paper, we propose a formal framework intended to precisely characterize types of middle-agents with a special focus on matchmakers,...
We propose a formal framework based on finite state process algebra for modeling service coordination in agent systems. The model is inspired by WS-coordination specification. Several participant agents can coordinate their actions towards reaching a semantically consistent outcome in a distributed activity. The model defines coordinator and participant agents and their generic interaction protocols...
In this note we show how our framework for formal specification and verification using FSP process algebra and FLTL temporal logic can be practically applied to check properties of agent systems that contain matchmakers.
In this paper we discuss experimental results obtained with a prototype implementation of an agent-based service for generic auctions that is currently under development. We configured the service to allow parallel execution of multiple English auctions with buyer and seller agents bidding from different machines. The experimental results to assess the performance of the service include latency and...
The contribution of this paper is to propose a simple approach for the design and implementation of code mobility using mobile software agents. The approach is demonstrated by its application to standard code mobility paradigms. We start from existing formalizations of code mobility paradigms and show how they can be used to derive standard UML sequence diagrams that describe agent interactions and...
We propose the use of finite state process algebra for modeling interactions between requesters, providers and middle-agents in global environments like the Internet. The results are threefold: (i) precise specification of interactions depending on type of middle-agent; (ii) understanding the requirements of parties involved in interactions; (iii) improvement of communication between designers and...
