Wireless and on chip Networks


Wireless networks

Wireless sensor networks (WSN's) are a cluster of wireless and often mobile devices, called nodes, which are set up within an environment to monitor its conditions and communicate with each other or a base station.  While there is a simple hierarchical structure in most sensor networks, ad hoc sensor networks do not have a base station and the nodes must devise a system of communication among themselves. In order for sensor networks to be useful, they must be able to effectively and securely communicate with one another. My research focuses on security, power management and time synchronization aspects for Ad-Hoc and sensor networks. 

Integrated Systems with Networks on Chip

A Network on Chip (NoC) is a new approach to System-on-a-chip (SoC) design that solves interconnect issues on SoC architectures. NoCs decouple the communications tasks from the computation tasks and offer well-defined protocols to eliminate contention on the channels. Ideas from computer networks have been borrowed to provide interconnections and communication among on-chip cores. My research focuses on Post-manufacturing tests. In particular, fault models and test pattern generation algorithms for testing NoCs, in an on-line and off-line manner.
