Outline of Final Research Achievements

In this work, the modification to the transport layer protocol is considered to effectively exploit the power saving functions of wireless network devices and protocols. In detail, based on the power saving profile of wireless devices such as start-up/sleeping time and power consumption values, the packet transmission timings are controlled with consideration of lower-layer protocols at wireless devices for power savings. The effectiveness of the proposed method is confirmed through computer simulations and experimentations with actual wireless network devices.
