The reason for selecting Maemo for this project is that the main focus
is on saving energy by maximizing sleep intervals for the 802.11b wifi
interface. Also, this technique is useful for only TCP streams and
there might be some UDP packet loss when the wireless interface is in
sleep mode. However, it can be possible to turn off the mechanism with
the help of a desktop widget when udp data needs to be handled.

Will you be interested in mentoring this project?
