WLAN Power Save by Header Compression and Packet Overhearing Reduction
David Lévy · 2014
Cellular, laptop, tablet and handheld devices support WLAN technology. In addition to the spectral eciency and security issues, power consumption is a vital issue in making the usage of these devices widespread. Efforts are underway in improving power conservation in those devices and thus increasing the duration between recharging the battery. Power consumption is mainly due to the transmission of WLAN packets and the receiver listening and receiving packets. Internet packets contain several headers for routing required in a complex network. Those networks are mostly wired networks using TCP/IP protocol. The WLAN transmitter is encapsulating all the TCP/IP headers and adding its own WLAN header. In some cases, the combined headers length represents a signicant portion of the total frame length.
