CIS Department Talk - April 28, 2005

The Department of Computer and Information Science & The Society of Computer Science Present

Speaker:Dr. Arjan Durresi, Department of Computer Science, Louisiana State University
Topic:Architectures for Heterogeneous Wireless Networks
Date:Thursday, April 28, 2005; 11:30am
Place:Keating Hall, Room 214


Heterogeneous Wireless Networks (HWN) that include both sensor and actor nodes are emerging as a critically important and disruptive class of computers. HWNs are supported by recent technological advances in low power wireless communications along with silicon integration of various functionalities such as sensing, communications, intelligence and actuation . HWN are based on a new platform, networking structure and interface that enable novel, low cost, high volume applications such as nuclear, biological and chemical attack detection and protection, home automation, battlefield surveillance and environmental monitoring.

To achieve the full potential of HWNs a new network architecture is needed. The new network architecture should be scalable, flexible, common for many applications and extendable without the need to redesign the whole network. Due to their nature and operational resource constraints, HWNs are vulnerable to various types of attacks. While designing the new network architecture for future HWNs, the research community has a unique chance to integrate security from the beginning as a fundamental part of the architecture.

In this talk I will present our research results in creating a strong foundation for the design and development of heterogeneous networks of sensor systems that are easy to manage, evolve, and secure, and that can provide quality of service. In particular, I will discuss our solutions for scalable, energy efficient, adaptive broadcast and routing for wireless, heterogeneous and mobile networks of both sensors and actors, which are also able to perform real time tasks. I will continue with our solutions for important security problems in HWNs, namely those of confidentiality and anonymity. In particular, I will focus on our algorithms for management of shared keys and anonymous communications in hostile environments. I will also discuss methods of integrating communications and security solutions and providing flexible tradeoffs between desired application-specific security levels and network resource consumption. Last but not least, I will discuss ways of integrating research activities into teaching, learning and training.


Dr. Arjan Durresi, IEEE Senior Member, is an Assistant Professor of Computer Science at Louisiana State University.
