Web-based Wireless Wake-on-LAN approach for Robots

The ability to wake up robots over a wireless LAN remotely can improve the power consumption performance of remote robots or cloud robotics system. This paper presents a solution for power management of a mobile robot, using web-based wireless Wake-on-LAN (WWoL). The focus in on power management of a mobile robot, but this approach is also suitable for most of the IoT mobile devices, and other systems that are designed to be used remotely. The proposed solution allows the targeted device to be powered ON and OFF remotely via a web-based dashboard. This approach was validated in a case study with an AR drone 2.0 and demonstrated substantial power optimization for the drone. In addition, security issues are explored when WWoL is deployed in remote control of mobile devices. It was established that power consumption is reduced when the drone is in a standby mode waiting for an operator to send a wake-on request message wirelessly, without compromising security posed by wireless remote access to the devices.
