Abstract :
Message Ferrying is a network paradigm in which a moving node or relay is used to transfer messages between sparsely deployed and further separated nodes in mobile ad-hoc networks. In this paradigm, the moving relay - also called message ferry (MF)- stores, carries, and forwards the messages. This paper analyzes the total delay time in transferring the message between source and destination nodes taking into account the effect of channel fading, path loss, and forward error correction. The performance gain in terms of delay and energy provided by moving relay over static relay and the optimal locations of the moving relay that minimize the total delay are determined. Both simulations and analytical calculations are provided.
