Promoting Cooperation in Multi-player Social Dilemma Models

Cooperation is ubiquitous at all scales of biological and social systems. Explaining the emergence and maintenance of cooperation has thus become a central problem in many scientific disciplines. Social dilemmas, such as the Prisoner's Dilemma, are well-known game theoretic models used to investigate the evolution of cooperation. In this talk, I will present a multi-agent simulation model we have built based on the N-Player Iterated Prisoner's Dilemma and discuss about some preliminary results we have obtained from our simulation studies. I will also briefly mention how we intend to expand the model, and talk about further research plan.

Policy-based Management of QoS in Service Aggregations

When provisioning services, organizations establish business relationships with their counterparts. These relationships are formally captured in Service Level Agreements, and include, among other things, the usage terms and conditions. Expressing preferences over these usage terms and conditions is a necessary first condition for reaching the agreements. In this talk, I will present a comprehensive policy model for capturing these preferences. Using attribute-value assertions and utility-value assertions policy authors can specify preferences over single QoS attributes as well as complete service configurations with greater flexibility. I will also present a QoS assertions model which is generic, domain-independent and conforms to the WS-Policy syntax and semantics.
