Abstract: It is difficult for devices to share location-based information with each other, when they are off-line. A method that builds and tests wireless ad hoc networks for Android devices based on WiFi Direct is tried, by which we implement the location-based information sharing, as well as we take the situation in which some devices in the group have a connection to the server into consideration. The test shows that the method could be a solution to the problem that devices can't share location-based information with each other or request information from the server to some extent, which is caused by network interruption.

Key words: location-based service, WiFi Direct, ad hoc network, location-based information sharing
