Method and System for Reducing Power Consumed By Mobile Wi -Fi HotSpots

A mobile device can act as a mobile Wi-Fi hotspot for other mobile devices in absence of wireless networks. However, in such scenarios, cost and battery usage associated with the mobile device acting as the Wi-Fi hotspot is much higher when compared to scenarios when it is not acting as the Wi-Fi hotspot. Therefore, there is a need for reducing the cost and battery usage associated with the mobile device acting as a Wi-Fi hotspot for other mobile devices.

Disclosed is a method and system for reducing power consumed and minimizing costs for a mobile device acting as a mobile Wi-Fi hotspot. The Figure illustrates a method for determining when a mobile device should turn OFF and stop acting as a mobile Wi-Fi hotspot. Initially, the mobile device scans for available Wi-Fi networks in its vicinity. The scans are performed periodically by the mobile device to detect any available Wi-Fi network. If a Wi-Fi network is detected, the mobile device checks a list of user approved Wi-Fi networks. In response to determining an approved Wi-Fi network, the mobile device stops acting as the mobile Wi-Fi hotspot by switching OFF the Wi-Fi connection. If the Wi-Fi network is not user approved, signal strength and internet connectivity of the Wi-Fi network is checked. If the internet connection is good, the user is prompted to approve the Wi-Fi network as a trusted network and save the Wi-Fi network on the mobi...
