Abstract:
Wireless sensor networks (WSN) are composed of a number of sensors probing their surroundings and disseminating the collected data to a base-station for processing. WSN have attracted lots of attention in recent years due to their potential in many applications such as border protection and combat field surveillance. Given the criticality of such applications, maintaining a dependable operation of the network is a fundamental objective. However, the resource-constrained nature of sensor nodes and the ad-hoc formation of the network, coupled with often an unattended deployment, pose nonconventional challenges and motivate the need for special techniques for the design and management of WSN. In this talk, we highlight the potential of repositioning the basestation, which acts as a sink node for the collected data, as a viable means for increasing the dependability of WSN. We show that base-station relocation can be very effective in optimizing the network functional and non-functional performance objectives and in coping with dynamic changes in the environment and available network resources. We further discuss a number of interesting research problem that we are currently investigating.

Biography
Mohamed F. Younis is currently an associate professor in the department of computer science and electrical engineering at the university of Maryland Baltimore County (UMBC). Before joining UMBC, he was with the Advanced Systems Technology Group, an Aerospace Electronic Systems R&D organization of Honeywell International Inc. While at Honeywell he led multiple projects for building integrated fault tolerant avionics, in which a novel architecture and an operating system were developed. This new technology has been incorporated by Honeywell in multiple products and has received worldwide recognition by both the research and the engineering communities. He also participated in the development the Redundancy Management System, which is a key component of the Vehicle and Mission Computer for NASA’s X-33 space launch vehicle. Dr. Younis’ technical interest includes network architectures and protocols, embedded systems, fault tolerant computing and distributed real-time systems. Dr. Younis has four granted and three pending patents. He received NASA’s faculty fellowship in 2005 and 2006. Dr. Younis is serving on the editorial board of the journal of Wireless Communication and Mobile Computing and the Journal of Computer and Applications and as the program co-chair of LCN’08 and ICC’08. He also served on the organizing and technical program committees of numerous conferences. Dr. Younis has published over 100 technical papers in refereed conferences and journals.
