Wireless sensor networks are composed of a lot of sensor nodes and they are used to monitor environments. Since many studies on wireless sensor networks have considered a stationary sink node, they cannot provide fully ubiquitous applications based on a mobile sink node. In this paper, we forecasted mobile course through data communication between a mobile sink and fixed nodes and proposed plan to renew routing path continuously without losing path in large scale networks based on multi-sink as utilizing soft handover technique which is for maintaining in case of a movement between networks of a mobile terminal. We verified performance of new protocol using Multi-Sink through experiment based on TinyOS and analyzed the result according to the different speed of mobile sink.
