Choe, I: Multimedia System Using Wireless Sensor Network

Wireless sensor networks are now playing an increasingly important role in many applications because of their small packet size, ease of deployment, low power consumption, wireless inter- communication capability, and self-organized dynamic topologies. In many applications the network is scattered in an ad-hoc manner within a region where it is meant to collect environmental data through multi-hop routing among all sensor nodes. In this project, I review and compare the existing multimedia systems based on wireless sensor motes. In addition, a basic audio & video system is developed using inputs from wireless sensor network consisting of multiple motes as the controlling parameters. The purpose of this project is to provide a testbed application that is capable of conveying the input from sensor motes in a fun and easy-to-understand way. The preliminary work demonstrates that non-tethered wireless sensor devices and MIDI triggers can be utilized together to provide multimedia output in unconventional ways and consequently provide an educational proof of concept system for the students interested in this field.
