Re: [Tinyos-help] Sending/Receiving Video with TelosB
Hello Sean, You may want to have a look at this paper [1]. Although it deals with micaZ, the scenario it focuses on is very similar to yours since telosB and micaZ have the same radio and their MAC layer implementation is pretty similar (in TinyOS). Good luck!

Re: [Tinyos-help] Sending/Receiving Video with TelosB
I have experimented with transmitting compressed audio on TelosB but video usually means much more data. With the tinyos packet size this means a huge number of packets. I think the issue here would be how long would you be able to support this configuration before the battery runs out on the motes. -vimal From: tinyos-help-boun...@millennium.berkeley.edu [tinyos-help-boun...@millennium.berkeley.edu] on behalf of Sean Dekker [sean.dek...@gmx.com] Sent: Thursday, October 18, 2012 7:02 AM To: Tinyos Help; Tinyos Help Request Subject: [Tinyos-help] Sending/Receiving Video with TelosB Hi everyone, Do you think it is possible to send/receive video with any quality between TelosB motes? Here is the scenario: There is a TelosB connected to PC using USB (serial port obviously) and there is another TelosB that has a digital cammra attached to it (using the 10 pin header).

Re: [Tinyos-help] Sending/Receiving Video with TelosB
Hi Sean you should do any previous research to be aware of the current advances and limitations with regard to the video transmission with wireless sensor networks. Search papers with the following topic: "wireless multimedia sensor networks". Then, you might find out valuable answers for your concerns. In particular, transmitting multimedia information requires high energy and computational resources. If you want to transmit video, you might need any special hardware or software to conduct the compression of the images (according with any standard, e.g., H264, JPEG2000, etc.) captured by the video sensor. In this sense, you shoud take care of the image format (CIF, QCIF...), the memory storage of telosb in order to store the images, etc... Again, you need a serial background.

Hi everyone, Do you think it is possible to send/receive video with any quality between TelosB motes? Here is the scenario: There is a TelosB connected to PC using USB (serial port obviously) and there is another TelosB that has a digital cammra attached to it (using the 10 pin header). Do you think this scenario is practical, considering the data rate and other criterias?
