Abstract

The link established in the Mobile Ad hoc Networks (MANET) is not stable and hence not reliable. We estimate the residual link lifetime (RLL) in MANET by measuring the distances between the link's nodes. We propose a mobile-projected trajectory (MPT) algorithm, which estimates relative trajectory between two nodes by periodically measuring the distances between them. Using the relative trajectory, the algorithm estimates the RLL of the link between the two mobile nodes. For comparison purposes, we derive a theoretical upper bound on the achievable prediction inaccuracy by any distance based RLL prediction algorithm with unknown but finitely bounded measurement error distribution. To account for velocity changes, the MPT is enhanced with a velocity-change detection (VCD) test.

The position of nodes and the time until which the nodes stay stable in the particular position are determined. The battery power of each node is calculated and thus the lowest hop energy of the path is determined. The energy consumed by the nodes will be more if the paths break up due to frequent movement of nodes. Hence alternate paths from source node to destination are identified and the packets are transmitted.
