Abstract: A mesh network system and a mesh network resource allocation method are provided. The mesh network system includes a first router having a processor. The processor is used to detect a network architecture, according to the network architecture, designate a role of a second router as a transmitting device or a receiving device, and assign a work to the second router base on the role. After receiving the work assignment, the second router processes an event of the work and continuously monitors an activity related to the work.

Abstract: An event detection method is for detecting if an event being predetermined exists in a detected environment, in which a first wireless unit, at least one second wireless unit wirelessly communicating with the first wireless unit, and at least one cooperating detection device are disposed. The event detection method includes a live CSI data obtaining step, a live CSI data reducing step, a cooperating data obtaining step and an event determining step. The live CSI data reducing step includes reducing a size of a plurality of live CSI data to generate a plurality of preprocessed live CSI data. The event determining step includes inputting the preprocessed live CSI data to an event classifier and processing a plurality of cooperating data to determine if the event exists.

Abstract: A distance-based packet filtering method includes a maximum filtering distance calculating step, a vehicle distance calculating step and a packet filtering step. The maximum filtering distance calculating step is performed to configure a processing unit to calculate a maximum filtering distance according to a dynamic adjustment distance parameter. The vehicle distance calculating step is performed to configure a modem to obtain a host vehicle location message and a vehicle-to-everything (V2X) safety packet. The V2X safety packet includes a remote vehicle location message, and then the host vehicle location message and the remote vehicle location message are calculated to generate a vehicle distance. The packet filtering step is performed to configure the modem to compare the vehicle distance with the maximum filtering distance from the processing unit to generate a comparison result, and judge whether the V2X safety packet is a passed packet according to the comparison result.

Abstract: The inventive system and method simulate the actions of a selected output device driver, and then record all the request and information for the document output. The quality and size of the document output are optimized according to the properties of the selected output device driver and supported resources before it is sent to the selected remote output device. When the document output data is sent to the remote site, it is restored and converted to a format acceptable by the selected output device driver for outputting a document of desired format and quality. The inventive method and system for the universal output driver facilitate the operations of network outputting so that a local host does not have to install the driver of the selected driver. Moreover, the invention can optimize the document output in accordance to the properties of the selected output device, thereby to ensure the quality of the document output and increase the transmission speed.
