Systems composed of interacting autonomous agents offer a promising software engineering approach for developing applications in complex domains. However, this <i>multiagent system</i> paradigm introduces a number of new abstractions and design/development issues when compared with more traditional approaches to software development. Accordingly, new(More)
Mobile agents represent a promising technology for the development of Internet applications. However, mobile computational entities introduce peculiar problems w.r.t. the coordination of the application components. The paper outlines the advantages of Linda-like coordination models, and shows how a programmable coordination model based on reactive tuple(More)
Pervasive and mobile computing call for suitable middleware and programming models to support the activities of complex software systems in dynamic network environments. In this article we present TOTA (&#8220;Tuples On The Air&#8221;), a novel middleware and programming approach for supporting adaptive context-aware activities in pervasive and mobile(More)
Pervasive computing calls for suitable middleware and programming models to deal with large software systems dived in dynamic mobile network environments. Here we present the programming model of TOTA ("tuples on the air"), a middleware for supporting adaptive context-aware activities in pervasive computing scenarios. The key idea in TOTA is to rely on(More)
The adoption of a powerful and expressive coordination model represents a key-point for the effective design and development of Internet applications. In this paper, we present the TuCSoN coordination model for Internet applications based on network-aware and mobile agents, and show how the adoption of TuCSoN can positively benefit the design and(More)
Coordination and access control are related issues in open distributed agent systems, being both concerned with governing interaction between agents and resources. In particular, while coordination deals with enabling interaction and making it fruitful, access control is meant to control interaction to make it harmless. We argue that this twofold facet has(More)
Massively parallel architectures require decentralized and scalable system policies. The paper presents and evaluates a set of local dynamic load balancing strategies inspired by diffusion and characterized by different scopes of locality: the goal is to compare their performance depending on the application dynamicity. The paper shows that only slowly(More)
Purpose – Emerging pervasive computing scenarios require open service frameworks promoting situated and self-adaptive behaviors, and supporting diversity in services and long-term evolvability. This suggests adopting a nature-inspired approach, where pervasive services are modeled and deployed as autonomous individuals in an ecosystem of other services,(More)
