Abstract: A wireless network system and a connection method for the wireless network are provided. A network device in the wireless network obtains the connecting route weights of a network base station and other network devices, the received signal strength indictor (RSSI) between the network device and the network base station, and the RSSIs between the network device and each of the other network devices. The network device obtains the routing decision values corresponding to the network base station and the other network devices and chooses the network base station or one of the other network devices corresponding to the highest routing decision value as the connection target. The network device can re-select its connection target according to environmental changes in the wireless network.

Abstract: A positioning system includes a storage device, a lidar and a controller. The storage device stores a global map. The lidar generates an initial local map. The controller rotates the initial local map to generate a rotated local map, compares the rotated local map and the initial local map separately with a plurality of partial areas of the global map, so as to obtain at least one similar area, calculates at least one candidate coordinates for a mobile device on the global map according to the center point of each of the similar areas, and calculates similarity scores according to each of the candidate coordinates, and selects the candidate coordinates having highest similarity score for use as coordinate of the mobile device on the global map.
