Abstract [en]

In this paper we will describe a positioning system based on synchronized IR light. Each node will be assigned a timeslot where they will send out an IR light. There is an IR camera that is also synchronized to the timeslots that will detect the position of each node and the ID that corresponds to the timeslot. To synchronize the clock of all nodes an IR flashlight is sent out that is detected by a photodiode on the nodes. The demo will show live video stream from a network camera where the ID and position of each node in view will be overlaid in real-time in the video.

Abstract [en]

In this paper we describe our work on building a large scale testbed for wireless video sensor networks. The site for this testbed is a zoo located in north Sweden, Lycksele djurpark. The zoo covers an area of about 47 hectares and is home to more than 400 animals, divided into 30 spieces. This gives us the possibility to build a large scale deployment rich of events to detect. The site is located in nothern Sweden where the winters are dark and cold and the summers have a lot of sunshine. This is an challanging environment for the sensor network deployment where the solar powered sensor nodes needs to be highly adaptive.
