Hello, We're doing experiments using wireless radio modules to detect events in a room by measuring the multipath behavior of the radio waves at a central location using an antenna array.
To do this, we require our modules to be constantly sending data. The actual contents of the data is quite unimportant, as we're only measuring the multipath behavior. When we use 802.11b radios, our experiments work correctly by simply sending a large file through the wireless network. Our RF analyzers show a large percentage (near 100%) of active radio duty with this method. However, we're now using IRIS motes and TinyOS to send radio signals from various points. Our program continuously sends a small message, and right after sendDone() is called, another message is immediately scheduled to be sent. With this setup, which is the best way I can think of for sending data at the highest possible rate, we're detecting a duty rate of less than 10%, which is insufficient for our experiments. I would like to know if anybody has ideas on how to push the radio to the max and have it send data continuously up to the maximum possible data rate. I've searched the mailing lists, but I have found nothing which is remotely similar to what I'm interested in.
