This paper proposes an algorithm to determine a mobile sink trajectory to cover the entire target area in a timely manner and dissemination of data with lesser delay. The proposed algorithm is based on Hilbert Space Filling Curve algorithm with dynamic control of graph order according to network density. The simulation results show that by overlaying smaller order curve on greater order curve in dense network we can achieve 50% better results.
