Greek-born Diomidis Michalopoulos did his graduate and undergraduate work at Aristotle University in Thessaloniki. He entered the University of British Columbia in 2009 where he is the Killam Postdoctoral Fellow. His research on wireless communications focuses on the area of cooperative communications, which is expected to play a principal role in the design of future wireless networks. The main idea behind the concept of cooperative communications lies in employing relay terminals for forwarding the information sent by a source terminal to a destination terminal. As a result, the link quality between source and destination is considerably improved, since networks obtain the flexibility of re-routing the information through obstacle-free paths, rendering cooperative communications a prime candidate for reliable communications anytime, anywhere.
Michalopoulos has proposed novel protocols in the concept of relay selection, where only a subset of the available relays is activated in a given time instance, ensuring that energy conservation is a major consideration in terminal set-up and use. This is extremely important because of the energy drain on large terminal hubs
