A power consumption measurement and control apparatus, method, and non-transitory computer readable storage medium thereof are provided. The power consumption measurement and control apparatus includes a power input line, a power output line, a sensing interface, a processing unit, a button, and a power consumption measurement and control unit. The power consumption measurement and control unit has a logic switch. When the logic switch is off and the processing unit receives an identification signal from the sensing interface, the logic switch is turned on. When the logic switch is on and one of the following conditions happens, the logic switch is turned off: (a) another identification signal from the sensing interface is received, and (b) the power consumption amount flowing out the power output line is below a predetermined threshold over a predetermined time interval.
Abstract:
A transmission control method for a vehicular ad hoc network system having a plurality of mobile nodes is provided. The mobile nodes include a source node, a destination node, and a plurality of relay nodes. The source node transmits a data packet to the destination node through the relay nodes. The method includes each mobile node capturing mobility information being periodically broadcasted from neighboring mobile nodes to correspondingly update the connection state table thereof, wherein the connection state table records the coverage remaining time between the mobile node and neighboring mobile nodes; when any of relay nodes determines that the coverage remaining time between the relay node and the subsequent mobile node is less than a predefined threshold, the relay node transforms into a proxy node, stores the data packet, and establishes a reliable sub-connection between the proxy node and a next proxy node or the destination node.

A coverage hole detection apparatus and method are provided. The coverage hole detection apparatus decides two boundary locations of a coverage hole according to (a) a time length from a time point when a user equipment (UE) has detected a disconnection from a first base station to a time point when the UE determines that a Radio Link Failure (RLF) has happened, (b) a time length from a time point when the UE receives an RLF report request from a second base station to a time point when the UE transmits an RLF report response to the second base station, (c) a location that the UE determines that the RLF has happened, and (d) a location where the UE transmits the RLF report response. The coverage hole detection apparatus decides the coverage hole according to the two boundary locations and a sensitivity range of the UE.
