Hari Balakrishnan’s pioneering computing contributions have been instrumental in developing innovative systems for our mobile world and protocols for efficient and reliable network communications. He introduced the concept of mobile sensing with the CarTel system, acquiring and drawing accurate inferences from noisy sensors on mobile devices for transportation applications including traffic measurement, road hazards, and driver safety. His work on the Cricket system showed how to combine radio and ultrasound for precise (3–5 cm) indoor location. To improve network resilience, he codeveloped distributed hash tables (Chord), resilient overlay networks, and a framework for verifiable border gateway protocol routing.
An IEEE Fellow, Balakrishnan is the Fujitsu Professor of Computer Science at the Massachusetts Institute of Technology, Cambridge, MA, USA
