  • Based on the estimated link lifetime, a novel routing mechanism is proposed in this paper to establish the reliable end-to-end path in Ad hoc networks. In order to describe the received signal strength continuously in time domain, the Newton Interpolation Polynomial is constructed according to the received signal strength; and then, the link lifetime is estimated with no prediction on speed, direction and other movement parameters. With the constraint of link lifetime and hop counts, the source nodes set up the paths to destination nodes in hop-by-hop mode. Simulation results show that the received signal strength can be described by Newton interpolation polynomial accurately while the mobile nodes are moving randomly; moreover, the route discovery times and packet drop ratio can be reduced by the routing mechanism.
