The purpose of P2P is to establish a direct WLAN connection between two devices without involving a router or AP for its operation. The P2P is known in Android devices as Wi-Fi Direct and can be operated from the Wi-Fi menu. Usually, the P2P role exists concurrently with the WLAN station role, which causes Android devices to operate in a WLAN multi-role state.
P2P is a WLAN role that typically has a short lifespan, in contrast to station or AP WLAN roles that exist from the moment that they have been started until they are explicitly terminated by the user. The P2P role is mainly used by a Miracast function in Android OS, for example, for mirroring the Android smartphone screen on other device, such as a smart TV or smart phone that has a WLAN module and supports Miracast functionality.
P2P may exist in three states: device, client, and GO. P2P functionality, after a connection, is similar to the WLAN station and AP functionality. However, P2P has supplementary functional behaviors that distinguish it from a standard station and AP operation, and allows different services to be used. P2P also has its own power save behavior that allows an additional battery.
