Definitions

Radio-on-demand wireless LAN (WLAN) defines a WLAN where each node (a power-hungry WLAN module) wakes up to communicate under a request, that is, each node is equipped with a low-power wake-up radio (WuR), which receives a wake-up message and activates its co-located WLAN module on demand.

Historical Background

Radio-on-demand WLAN realizes the wake-up control of a WLAN module. This function becomes urgent because nowadays WLAN modules are widely embedded into mobile devices (such as smartphones) driven by batteries with limited capacity.

A WLAN module can have different states with different power consumptions, as shown in Table 1. The power relationship usually is Transmitting >  Receiving >  Idle >  Transition >  Sleep >  Power-off. Without any power-save mechanism, a WLAN module is in the continuously awake mode (Idle, Receiving, or Transmitting). Analysis of traffic statistics indicates...
