His research has been supported by government and industry funded projects such as the European Commission, French Ministry of Education and Research (ANR), CNRS, THALES, Thomson, Siemens, Ericsson and Orange Labs. among others. He published more than 150 papers on refereed journals and conferences and he served on various program committees of conferences in computers and communications. Nowadays, interests in Healthcare Monitoring System (HMS) based on Wireless Body Area Network (WBAN) and Cloud computing have grown considerably due to the increasing aging population. HMS expected to reduce healthcare expenses by enabling the continuous monitoring of patient health remotely during their daily activities. From a medical point of view, WBAN will emerge as a key technology in providing real-time health monitoring and diagnoses of many life threatening diseases (Heart attack, Stroke, Epilepsy, Diabet, …). This talk will focus on the WBAN in terms of emerging wireless technologies (supporting infrastructure and technology), HMS architecture and its applications (Continuous Monitoring and Assisted Living) and challenge design issues related to WBAN security and fault management.
