One of important challenge issue in the wireless sensor networks is limitation energy in battery of intermediate nodes, so using a suitable routing algorithm can improve this problem. In the wireless sensor network, sink node uses neighbour in order to sending interest message into network. The neighbour nodes around of the sink have important duties. The neighbours of sink all times are using by sink node in order to receiving data, so it will consume more energy from sink node. Moreover, when neighbour nodes of sink go to dead mode, sink node could not propagate its packet. In this paper we have proposed a new algorithm by using mobile sink nodes to prevent energy wasting and also increase network lifetime. The result of simulation showed that life time has increase in an efficient way and has increase about two times in the compare of OPP algorithm.
