An Algorithmic View of Smart Living: The Next Frontier

Date & Time: 29/11/2019, 4:00 pm
Venue: Faculty Hall, Indian Institute of Science

The advent of wireless sensor networks and Internet of Things (IoTs) are making our lives increasingly dependent on a wide variety of cyber-physical systems (CPS) and smart services (e.g., smart energy, transportation, healthcare, agriculture, etc.), while aiming to improve quality of life. The availability of rich mobile devices like smartphones are also empowering humans to act as sensors to collect fine-grained information via crowd sensing, resulting in actionable inferences and decisions. This talk will first provide a “smart living” vision and highlight the underlying research challenges. Next, it will formulate fundamental problems related to sensor data fusion, coverage and connectivity, mobile charging, security, network lifetime and resource trade-off. Novel solutions will be designed based on randomized and approximation algorithms on graphs, optimization techniques, geometric probability theory, uncertainty reasoning, trust model and game theory. Case studies and experimental results will be presented where possible. The talk will be concluded with emerging applications of sensors and IoTs, followed by directions of future research.
