Aamir Mahmood

Docent|Associate Professor

Background

Aamir Mahmood received the Bachelor degree in Electrical engineering from National University of Sciences and Technology (NUST), Pakistan, in 2002. He received his Master and PhD degrees in Communications engineering from Aalto University, Finland, in 2008 and 2014 respectively. He also worked at Nokia Research Center, Finland, for 6 months in 2014. He was a Visiting Researcher at the department of communications and networking, Aalto University, from September 2015 to June 2016.

Area of interest

My research interests include adhoc and sensor networks, wireless protocol design and analysis for ultra-reliable communications, interference analysis / coexistence management.

Research

The industrial monitoring and control applications demand resilient communication solutions for their reliable and safe operation. On one hand, the industrial applications have stringent communication reliability and delay constraints, and on the other hand the industrial environment poses challenging wireless propagation conditions. In this respect, I will investigate the channel quality metrics that can enable the wireless sensor systems to adapt under the dynamics of the industrial environment as well as to cope with the interference from the coexisting wireless systems.
