Abstract:

In Ad hoc networks, nodes can communicate without any pre-existing infrastructure. Topology is created dynamically and can change upon nodes mobility. Hence, the function of routing becomes very complex. Many protocols are now standardized to calculate routes between a couple of nodes in an ad hoc network. These protocols find shortest routes based on the number of hops between source and destination.

When extending the routing function to take into account quality of service parameters such delay, available bandwidth, loss probability, etc., the problem becomes more and more complex. In this seminar, we present works that we proposed in this topic that permits to find routes offering quality of service by using the OLSR protocol for ad hoc networks.

After working at the university of Versailles and INRIA, Khaldoun Al Agha is now Full Professor at the Paris XI University. He created and conducts the Networking group within the LRI Laboratory (Laboratory of Research in Computer-Science). Khaldoun Al Agha takes an active part in various research projects in the field of network mobility. Its research relates to the resource allocation in cellular networks (GSM, GPRS, UMTS) and on IP network mobility (Mobile IP, ad hoc networks ...). Khaldoun Al Agha develops his research within several national and international projects and cooperation.
