Abstract
A method and computer program are provided for handing off a mobile device in communication with a first wireless system having a first network address to one or more other wireless systems within communication range of the mobile device. The method and computer program include periodically monitoring by the mobile device of communications from the first wireless system and the other wireless systems, calculating a signal strength associated with each of the monitored communications, selecting one of the other wireless systems, and transferring communication to the selected wireless system upon detection of a predetermined threshold of the signal strength associated with the first wireless system.
