The energy efficiency is an important key point in wireless sensor network. In general designing a routing protocol, without only transmitting sensing data back to sink node it need provide better energy efficiency or increase wireless sensor network efficiency. In many proposed network model, we use cluster-based network model to implement our mobile sink routing protocol. By setting up a sink routing schedule queue, mobile sink has a useful path routing through clusters. It also provides an energy efficiency way with decreasing communication, and improves the wireless sensor network lifetime. In this paper, the verification simulation is also executed to prove the proposed "a mobile sink routing protocol" can increase the wireless sensor network lifetime.
