Sanjay founded the Network Research Laboratory in July 1999. His research work primarily focuses on higher layers of communication protocols in the areas of Adhoc/Wireless Sensor networks (Project Sensar) as well as Efficient Distribution of Content in Multi-Rate Multi-channel Wireless Mesh Networks (Project Aiolos) as well as the Secure Wireless Mesh Network (Project Swimnet). He has been the recipient of a number of competitive grants from ARC, Industry and other funding bodies, with a total value of over A$3M (jointly). During the past five years at . UNSW, he succeeded in publishing 2 books, over 15 journal articles (including IEEE Transactions articles), 4 book chapters and over 100 refereed conference/workshop papers in high quallity forums (Mobihoc, IWQoS, NOMS, ICC, PIMRC, etc.) and two provisional patents. Two papers co-authored by his students have won the best paper award in International conferences. Sanjay is the principal author of the book "Engineering Internet QoS" Artech House, Boston). Over 20 universities are using this book worldwide. He is also a co-editor of the book Wireless Sensor Networks: A Systems Perspective .
Sanjay has also worked as an industry consultant for major organizations such as Canon Research Lab (CISRA), DSTO, Lucent and Fujitsu. At Fujitsu Australia Ltd, he was responsible for developing a module for their LAN/SDH interface. As a visiting scientist, he was responsible for developing a part of Quality Assurance Language for monitoring network QoS performance at Columbia University.
He was formerly also associated with the Network and Prevasive Computing (NPC) program of NICTA and a project leader of the wireless networking project at the Smart Internet CRC. Sanjay is a participant in CeNTIE project project funded by the commonwealth Govt. through Building on IT Strengths (BITS) Advanced Networks Program (ANP).
Sanjay is currently supervising a large number of PhD candidates. A complete list of students can be found here.
