Abstract
Today's mobile applications are playing a key role in the IT world, encompassing various fields such as sports, entertainment, health and sciences, and games. This article describes the Danger Notification and User Navigation (DNUN) application, which works in conjunction with a geolocation system to save and navigate to an object's location for immediate or later use from anywhere on Earth. It notifies other contacts about a user's location through either broadcast or multicast communications. DNUN also notifies application users about an object's location when they have forgotten it.
