Time : 4:45 PM
Location : Weston Lecture Hall 1, School of Architecture, NJIT

About the Speaker

Dr. George F. Elmasry received his B.Sc. degree in Electrical Engineering from Alexandria University, Egypt, and his M.S. and Ph.D. degrees in Electrical Engineering from NJIT. He currently heads the Networking and Communications Division at DSCI with a focus on the Future Combat System (FCS) tactical networks for the US Army. The FCS is composed of multiple mobile ad-hoc networks with hierarchical architecture. Before joining DSCI, he worked for General Dynamics C4S in the Warfighter Information Network-Tactical (WIN-T) group where he spearheaded research in the areas of resource management and capacity analysis for WIN-T which is the tactical core network for the US Army. Prior to General Dynamics, he worked for Lucent Technologies in the Wireless Networks Wideband CDMA group. His research interests include the areas of wireless networking, ARQ, joint source and channel coding, and multidimensional interleaving. He holds over 35 publications and patents in these fields. He is also actively involved with technology conference organization and paper reviews.

About the Talk

Addressing Quality of Service (QoS) in military wireless ad-hoc communication networks involves unique challenges due to imposed tactical requirements and conditions, such as heterogeneous traffic with stringent real-time and survivability requirements, mobile wireless nodes in hostile environments, and limited spectrum availability. Encryption adds another layer of complexity because the partitioning of the network into plain text (unencrypted) and cipher text (encrypted) parts that, by definition, cannot communicate QoS information to one another. A typical communication shelter consists of a number of unencrypted LANs connected to a packet-encrypted backbone network. This talk presents a partitioned QoS approach focusing on QoS management at the unencrypted LANs that complements QoS management done at the encrypted backbone. Some of the outlined QoS techniques for unencrypted LANs were used for Warfighter Information Network-Tactical (the future army tactical backbone network).
