Wireless sensor networks, which are used in ubiquitous application field in a variety of ways, refers to a network composed of wireless sensor nodes that are disseminated in specific locations in order to detec certain events. Since many studies on wireless sensor networks have considered a stationary sink node, they cannot forward data without data loss while a sink node moves. Previous researches used broadcasting or updates of routing tables for a Tracking of mobile sink node. But they need to reset up paths frequently. In this paper, we propose a method to continously update routing paths and track a mobile sink node by on a Grid-based structure of the cluster. A sink node uses a separate table to track and update its location in our works. In addtion, the information that is necessary for the tracking of the sink node when a sink node moves between grid inside and grid is different. Therefore, we differed in a tracking method in consideration of such a point by the sphere of movement of the sink node. The reliability of data transmission has been validated by simulation. As a result, our work consume similar energy consumption even a sink node use an extra table. Also the success rates of data transmission increased.
