“…Potentially call information could be propagated this way and system integrity ensured. Another area we had some inspiration from was the work on semantic overlay networks [3] and the idea of cluster formations based on certain agent properties. A handler agent that can only answer calls of a specific type seems like a reasonable property to use for that purpose.…”

Abstract. Motivated by demands from the commercial world for software systems that can assist in the reorganisation of processes for the purpose of reducing business complexity, we discuss the benefits and challenges of the multi-agent approach. We concentrate on the engineering aspects of large scale multi-agent systems and begin our exploration by focusing on a real world example from the call centre industry. The critical call routing process seems appropriate and useful in presenting our ideas and provides a good starting point for the development of agent organisations capable of self-management and coordination. The main contributions of this work can be summarised as the demonstration of the value of agent organisational models that do not replicate the typical hierarchical structures observed in human organisations and that a quite basic peer-to-peer structure produces very similar performance indicators to a mature simulator that uses conventional techniques, suggesting further improvements may readily be realized.

Abstract-Semantic overlay could improve query performance in peer-to-peer (P2P) systems. When peers join or leave frequently, it will lead to network traffic surge, since most semantic search methods maintaining a large number of routing tables. In this paper, we address these problems by proposing Interest Attenuation Search(INS), a novel efficient peer-to-peer semantic search approach based on interest attenuation policy. In INS, the interest attenuation policy is introduced to help peers decide whether to forward messages. Before peer floods the request in semantic overlay network(SON), it will check the history information about the request message, then uses INS to make forwarding decision. Simulation results show that INS significantly improves query performance and reduces the traffic overhead generated by unstable network environment.

Abstract. This paper presents Clouds, a peer-to-peer protocol that guarantees both anonymity and censorship resistance in semantic overlay networks. The design of such a protocol needs to meet a number of challenging goals: enabling the exchange of encrypted messages without assuming previously shared secrets, avoiding centralised infrastructures, like trusted servers or gateways, and guaranteeing efficiency without establishing direct connections between peers. Anonymity is achieved by cloaking the identity of protocol participants behind groups of semantically close peers. Censorship resistance is guaranteed by a cryptographic protocol securing the anonymous communication between the querying peer and the resource provider. Although we instantiate our technique on semantic overlay networks to exploit their retrieval capabilities, our framework is general and can be applied to any unstructured overlay network. Experimental results demonstrate the security properties of Clouds under different attacks and show the message overhead and retrieval effectiveness of the protocol.
