Sink mobility is one of the efficient solutions to sink hole or energy hole problem which is usually caused by multi-hop communication using a static sink. However, the design of an efficient path for the mobile sink is an important issue. In this paper, we propose a novel algorithms to determine rendezvous point (RP) based dynamic path for mobile sink called delay aware energy density based trajectory (DAEDT). The DAEDT designs an energy efficient delay bound path for the mobile sink. In order to balance energy consumption among the sensor nodes, the proposed algorithm selects RPs based on the energy density of the sensor nodes. The DAEDT is also presented with a detour criteria following some threshold. The algorithm is extensively simulated and the results of DAEDT are compared with some existing schemes to show its effectiveness over various performance metrics. The simulation results are further validated through hypothesis testing using ANOVA.
