The GNAN research group headed by Professor Raghupathy Sivakumar focusses on
researching and developing network architectures and protocols for the future
Internet. We envision the future Internet to exhibit, among other things,
three key characteristics: a much larger and more dominant mobile user
populace enabled by the advancement and widespread pervasiveness of wireless
networking technologies, increased sensitiveness to the diversity of Internet
applications by way of supporting fine grained quality of service
provisioning, and ease of extensibility, allowing for network providers to
upgrade Internet services on-the-fly, and thus keep pace with the growing
diversity of end-user applications. The following are some specific areas that
the group currently works in:
- Network architectures for next generation wireless networks, including
conventional cellular networks, ad-hoc multihop networks, and other hybrid
network models. Algorithms for wireless network protocol layers including the
medium access control, network, transport, and middleware layers.
- Architectures for providing quality of service (QoS) in the future Internet
in heterogenous wired and wireless network environments. Special focus areas
include scalable core-stateless approaches and robust overlay network
architectures. Algorithms for supporting QoS assurances in heterogenous
environments, for metrics including bandwidth, delay, jitter, etc.
- Approaches for making the Internet extensible in a scalable fashion.
Research areas include macro-level network architectures and micro-level node
architectures. Identifying the use of network extensibility in specific
areas like mobile computing and QoS provisioning. Architectures and algorithms
for advanced network capabilities like self-healing and self-evolution.
