Multi-hop routing device and method reflecting link life time by node movement

摘要

PURPOSE: A multi-hop routing device and a method thereof for reflecting a link lifetime by node transfer for considering a predicted link continuance time are provided to improve overall routing performance by minimizing the disconnection of the link in mobile ad hoc network. CONSTITUTION: A satellite information receiver(110) periodically receives a message the location information of each node. The satellite information receiver calculates the traveling direction and speed of each node. A signal processor(120) generates the routing request message. A predicted link continuance time calculator(130) calculates the forecast link lifetime by using location and speed of each node.
