Demo Abstract: HajjCPS - A Cyber Physical Environment for Providing Location-Aware Services to a Very Large Crowd

In this demo we will present a suite of smartphone applications that support location-aware, personalized multimedia services to a very large crowd with the help of a cyber computing infrastructure. As a proof of concept, we target Hajj where more than 5 million pilgrims perform spatio-temporal activities. The cyber-physical system creates an ad-hoc social network among pilgrims, their family members, Hajj authorities, vehicles that provide services to the pilgrims, medical doctors and hospitals, and the city admins. The crowdsourced multimedia data from the suite of smartphone applications are captured by the cyber environment, processed to extract context information, sent to a cloud environment for real-time query processing, and finally shared with a very large crowd. The framework has been deployed since 2014.
