Abstract: In the case of scarce or damaged basic network facilities, Android phones can use Wi-Fi Direct technology to create temporary communication networks. In the past, communication networks based on Wi-Fi Direct technology were mostly connected in standard mode, and the transmission range was limited to a single group. In this paper, an autonomous networking method was used to create a Wi-Fi Direct group. With the help of P2P interface and Wi-Fi interface, a communication network that could establish a connection without user interaction was constructed, and the transmission range was extended to multiple groups. Through practical demonstrations, the networking mechanism of multiple connections was clarified.
