An interesting approach to the design and development of the future Inter-net foresees a networked service ecosystem capable of seamlessly offering services for human-to-human, human-to-machine and machine-to-machine interactions. This chapter builds in this direction by describing a distributed component-ware framework for autonomic and situation-aware(More)
In this paper we show how pervasive technologies can be employed on a public-display advertisement scenario to enable behavioral self-adaptation of content. We show this through MyAds, a system capable of exploiting pervasive technologies to autonomously adapt the advertisement process to the trends of interests detected among the audience in a venue. After(More)
Peer-to-Peer (P2P) is a flexible architecture that let a network grow up in an arbitrary way by adding more and more peers providing resources to the whole system. If uncontrolled, however, this growth might lead to stability and reliability problems, due to the fact that any host might join the network, no matter whether it may provide guarantees or not.(More)
We describe a prototype of trading system platform populated by agents who autonomously decide to buy and/or sell items according to a set of local needs which arise dynamically (also by possibly accessing information provided by pervasive devices) by in the process of fulfilling a given overall utility. The market has combinatorial nature in a way that(More)
E-business organizations commonly trade services together with quality of service (QoS) guarantees that are often dynamically agreed upon prior to service provisioning. Violating agreed QoS levels incurs penalties and hence service providers agree to QoS requests only after assessing the resource availability. Thus the system should, in addition to(More)
This paper presents and studies a reliable multicast protocol whose objective is to deliver a message to all intended destinations, despite possible crashes of the sender and other processes, and communication failures. The protocol enables QoS metrics such as absolute and relative latencies and the probability of reliable delivery, to be negotiated prior(More)
The paper addresses the problem of reliably multicasting messages within a cluster, with an advertised latency bound that would be met with a preset confidence level. The system developed here offers, prior to an invocation, probabilistic guarantees on reliability and latency bounds and, post invocation, strives to achieve the offer chosen by the(More)
