<Abstract>

This paper proposes a method of prolonging network lifetime using the mobile sink node in 6LoWPAN/RPL. According to dynamically changing the sojourn time of the sink node, the proposed method prolongs the network lifetime. By deciding sojourn time appropriately, proposed method to reduce the power consumption of the node load is concentrated. Simulation results show the effectiveness of the proposed method.
