The content and presence updates were used to transmit updates to nearby nodes over an ad hoc network using duty cycles; the authors' algorithms synchronize the transmissions of nodes periodically. By this approach, nodes can save battery power without missing updates from their neighbours by switching off their network cards. The algorithms and protocols used here provide more security. The mobile phones that have rich media and wireless networking capabilities has ushered in a new paradigm in mobile computing with new emerging social behaviours. New enabling technologies now allow users to search, locate, download, and share dynamically created content with friends and family from their mobile devices.
