With the wide use of smart phones, the performance and power-saving issue is also increasing. Since the battery capacity is limited, the energy-saving technology is very important to mobile devices. In this study, we proposed an approach to observe energy consumption of smart devices, especially while smart devices are connect to a wireless hotspot with UDP protocol.
A new asynchronous medium access control (MAC) protocol using dual busy tone for channel reservation, called HCRBT, is proposed. Compared with legacy channel reservation MAC protocols, where channel reservation information (CRI) is broadcasted by piggybacking it in a packet, HCRBT improves the reliability of channel reservation by using dual busy tone. In HCRBT, CRI is broadcasted by busy tones rather...
