Reducing Inaccurate Activations of Wake-on-demand In-vehicle Communication

The authors are examining ways to implement a wakeup receiver for an in-vehicle router because it is vital to reduce the energy consumption by the in-vehicle router connected to a cloud network. The wakeup receiver keeps all the other devices except itself from being active until it receives a specific data frame. Consequently, in-vehicle modules can remain longer in an idle state, avoiding unnecessary energy expenditure. However, the wakeup receiver based on the current specification only monitors a given frame length, which causes inaccurate activations sometimes upon receiving signals with the same frame length from other stations. This paper proposes a novel system to reduce inaccurate activations in wake-on-demand systems, by using the probe request of a wireless LAN as wakeup signals, where dummy frames are attached to the probe request. This makes the wakeup signal unique and reduces the likelihood of inaccurate activations caused by frames from other stations.
