WBAN presentation by Samaneh Movassaghi – 14 Dec 2017 10-11am – A120


Interference Mitigation and Self-Organization for coexistence of Multiple Wireless Body Area Networks


Recent developments and technological advancements in wireless communication, MicroElectroMechanical Systems (MEMS) technology and integrated circuits has enabled low-power, intelligent, miniaturized, invasive/non-invasive micro and nano-technology sensor nodes strategically placed in or around the human body to be used in various applications, such as personal health monitoring. However, Due to the scarce limitation of resources in these networks in terms of small battery capacity, limited bandwidth and their dense deployment in crowded areas, the practical deployment of these networks is yet at stand by. WBANs are cyber-physical systems that are designed to provide a vast era of applications from real-time health care to personal entertainment services. They cannot be considered as static networks, therefore, they are subject to change and must able to cope with the variations in their network. These variations can be in terms of topological changes, variations in traffic patterns, changes in overall load on the network. Additionally, the environment in WBANs is nondeterministic which implies taking the same action on the same state for two different occasions may lead to different states. Therefore smart techniques must be deployed in these networks to take these unknown dynamics into account. However, adaptive approaches require frequent exchange of information and lead to a linear cost in updating information. In addition, the broadcast nature of the wireless spectrum and the limited radio bandwidth leads to interference between devices involved in communication between coexisting WBANs. In addition, power is a scarce resource in WBANs as sensors are battery driven. Moreover, future WBANs are prone to excessive interference in densely populated areas which can significantly degrade network performance and quickly depletes the energy of WBAN nodes. This issue is highlighted even in medical applications that deal with mission critical information where unreliable data collection endangers the life of millions of people. This talk encounters these challenges for the practical deployment of WBANs to increase their throughput, minimize interference, increase network lifetime, adapt to network variations, prolong battery savings, be able to self-organize and last but not least be simple as possible to avoid computational calculations which eat up the energy of the network.


Samaneh Movassaghi received a B.Sc. from University of Tehran in 2009 and a Master by Research in Telecommunication Engineering from the University of Technology, Sydney in 2012. She is currently a PhD student at the Australian National University (ANU) and is conducting research in the field of Wireless Body Area Networks. She has authored over 20 research articles with over 700 citations in her research [h-index=10] . Samaneh was recently recognized for cutting edge research on wearable networks (wearables). She was awarded as ICT Student of the year at the Australian Computer Society (ACS) Digital Disruptor Awards. She was recently awarded a Google Fellowship in Networking for her PhD research. Samaneh is selected as one of the seven researchers across Australia’s leading research organizations, CSIRO and NICTA, featured as the CSIROseven campaign (http://seven.csiro.au/Samaneh). Such selection was made on a basis of Samaneh’s excellent research outcomes in wearable technology. Samaneh won the 2015 NASSCOM Student Innovation Award for IT-enabled Business Innovation. This award recognizes excellence in the field of Information Technology, which particularly promotes technical innovation and is awarded to one person Australia-wide per year. She has been recently interviewed by various media specifically, SBS and ACS and featured in more than 15 newspapers and magazines Australia-wide, some of which are as follows: The Herald Sun newspaper, Sydney Telegraph, The Australian newspaper, Sunday Style’ magazine, WHO magazine, The Deal, The Australian, In the Black, Virgin – Voyeur, Vice, The Australian Financial Review, etc. Samaneh has also been providing consulting advice for a number of start-ups in e-health. Samaneh was also elected as one of the 5 representatives of ANU in the GYSS 2016 summit. This selection is highly competitive and is conducted across all faculties ANU-wide. She has also been actively involved with a number of hackathons where she won the “spirit of healthhack award” from the healthhack hackathon and the 2nd prize at the Unearthed Hackathon in Melbourne 2015. She has also won innovation prizes at research showcases held at UTS and UNSW in 2014 and 2015, respectively. Samaneh was also a recipient of the University of Technology, Sydney President Scholarship (UTSP), The Australian National University Postgraduate Scholarship Award (APA), and the CSIRO Top-up Scholarship.
