Internetworking Program Guest Speaker Dr V Vaidehi Monday, June 24, 2013 11:00 am Room B226 Sensor Networks and its applications in Surveillance and Healthcare By-­‐ Dr V Vaidehi Professor & Head Dept. of IT, MIT Anna University Chennai-­‐44 India Email id: [email protected] Abstract: Recent advances in sensor networks have greatly encouraged their usage in security, surveillance and healthcare applications. This presentation focuses on the issues, methodologies and algorithms involved in creating multi sensor based surveillance system and healthcare system. The objective of the surveillance system is to automatically collect real-­‐time information, to detect, identify, track people for situational awareness and intrusion detection. The system combines the Wireless technology and Ethernet technology to get data from sensors and cameras for better understanding of the situation. Complex Event Processing (CEP) technology is applied for processing and identifying patterns of interest from multiple streams of events. Tracking is done by Kalman Filter. To prolong the lifetime of the wireless sensor network, power optimization techniques are employed in localization and routing. In healthcare application, we use wearable wireless body sensors to monitor a home alone chronic diseased patient. It involves the effective collection of sensor data, sensor web enablement of the health data, finding the abnormities in vital signs and fall of a person.
