Abstract: A power management device and a management method thereof are provided. The power management device includes a switch, a detection circuit and a controller. The switch receives an external power. The detection circuit receives an internal power and at least one operation power. The detection circuit determines whether at least one of the internal power and the operation power is in a preset specification range or not to generate a protection activate signal. The controller sets a protection flag according to the protection activate signal, and generates a control signal according to the protection flag by executing an application program. The controller transmits the control signal to turn off the switch.

Abstract: A wireless communication method of a wireless communication device is disclosed, wherein the wireless communication method includes the steps of: establishing a link with a first access point, and obtaining a BSSID list of a plurality of access points of a self-organizing network from the first access point of the SON during a link process; determining at least one candidate access point from the plurality of access point according to the BSSID list; and selecting one of the at least one candidate access point to establish a link.

Abstract: A topology path obtaining method of a mesh network and a system configured to obtain a topology path of the mesh network are provided. In the method, a topology query packet transmitting step is performed to configure a root access point to transmit a topology query packet to a plurality of extended access points. A topology response packet transmitting step is performed to configure each of the extended access points to transmit a first topology response packet to the root access point according to the topology query packet. A topology path generating step is performed to configure the root access point to collect and process a plurality of the first topology response packets and a second topology response packet to generate the topology path. The topology path includes a connection relationship between at least one client device and one of the root access point and the extended access points.

Abstract: A connection establishing system and method for a mesh network is provided, the mesh network includes a first transceiver and a second transceiver, the method includes performing a secure connection procedure including: transmitting, by the second transceiver, a secure connection request signal including a identifier to the first transceiver. The first transceiver encrypts the authentication message by using a public key corresponding to the identifier to generate a secure connection response signal and transmit the same to the second transceiver, the second transceiver decrypts the secure connection response signal by a private key to generate a decryption message and transmits an association request signal including the decryption message to the first transceiver.
