Abstract: Autonomic communications  are meant to offer adaptive, optimized and opportunistic services to network users, based on user requests (such as QoS needs) and on information that can be gathered on-line about available resources. At the beginning of our seminar we will provide theoretical results to show that such services can be effective. First we will prove that "sensible" routing policies based on local information are better than non-informed random policies . Secondly we will show that it is possible to travel from source to destination even when the routing direction at each step may be incorrect . Then we will present the CPN protocol  for QoS driven autonomic routing, and illustrate its performance with numerous measurements from a wired test-bed and from an ad-hoc network implementation [5,6].
Brief Bio: Erol Gelenbe has previously held chaired professorships in Belgium and France, at Duke University and at the University of Central Florida. One of the pioneers of the field of computer and network performance evaluation, he has contributed several firsts in the field of networks, including the first performance evaluation of link control and window protocols, the first optimal control of random access protocols, the first implementation of an ALHOA-like fibre optics network, and the design of the first packetized telephone switch architecture. He is Fellow of IEEE, ACM, and IEE, a Member of Academia Europaea, has received several honorary doctorates and research awards in France, Belgium, Turkey and Italy. He is a Commandatore of the Republic of Italy, and an Officier du Mérite of France.
