Dear all,

We are happy to announce that Pedro M. Ruiz will
present part of his work on wireless Ad-hoc networks at next week's NRG.

His talk will take place next Monday, December 6th at 4:00 pm at the
graduate lounge. The title and abstract of the talk along with a short
bio of Dr. Ruiz follows.


Title: Mobility-Aware Mesh Construction Algorithm for Low Data-Overhead
Multicast Ad hoc Routing


We study the problem of controlling data overhead of mesh-based
multicast ad hoc routing protocols by adaptively adding redundancy to
the minimal data overhead multicast mesh as required by the network
conditions. We show that the computation of the minimal data overhead
multicast mesh is NP-complete, and we propose a heuristic approximation
algorithm inspired on epidemic algorithms. In addition, we propose a
mobility-aware and adaptive mesh construction algorithm based on a
probabilistic path selection being able to adapt the reliability of the
multicast mesh to the mobility of the network. Our simulation results
show that the proposed approach, when implemented into ODMRP, is able to
offer similar performance results and a lower average latency while
reducing data overhead between 25 to 50% compared to the original ODMRP.


Pedro M. Ruiz received his B.Sc, M.Sc. and Ph.D degrees from the
University of Murcia, Spain. He works as Research Staff at the
Department of Information and Communication Engineering (DIIC) at the
University of Murcia (UMU), supported by a "Ramon & Cajal" position.
Prior to joining UMU in december 2003, he has worked as R&D Manager at
Agora Systems S.A. He also coordinated several research activities at
RedIRIS, the Spanish National Research Network, and he worked as a
part-time assistant professor at the Univ. Carlos III of Madrid. During
these years, he has acted as "Principal Researcher" in several research
projects mainly funded by the European Union, Spanish government and
private companies.

Dr. Ruiz is in the editorial board for the "International Journal on
Parallel, Emergent, and Distributed Systems" and he is participating in
the Technical Comitee of serveral conferences. In addition, he has
served as a reviewer for major IEEE journals and conferences. In fall
2003 he was awarded a Ramon y Cajal position by the Spanish Ministry of
Science and Technology. His main research interests include mobile and
ad hoc wireless networks, adaptive multimedia systems, future mobile and
wireless networks and distributed applications and services. He is a
member of the IEEE Communications Society.

Presently, he is enjoying a post-doctoral visiting fellowship at the
networking group of the International Computer Science Institute (ICSI)
in Berkeley. During this fellowship his work is mostly focused on the
integration of mobile ad hoc networks with IP-based access networks and
the enhancement of multicast ad hoc routing protocols.
