在移动无线传感器网络中，提高数据发送成功率和减小网络能量消耗是移动Sink路由协议研究的重点。提出一种基于代理机制的数据传输协议（ABR），论证了利用“代理节点足迹链”在提高数据发送成功率方面的优越性；采用节点位置收敛和直接更新相结合的Sink节点位置更新策略，有效平衡网络能耗与传输时延的矛盾。仿真结果表明ABR在提高网络性能方面有很大的优势。

英文摘要：

In mobile wireless sensor networks, it has attracted many scientists＇ attention that how to improve the packet transmission rate while reduce the network energy consumption. In this paper, an Agent-based Routing protocol （ABR） is proposed, which transfers packet efficiently based on agent node chain. Also a new method of updating Sink location is introduced, which combines the location convergence and location update by proxy node to source sensor. This strategy can make a better balance between energy consumption and average transmission delay. The results show that ABR pro- tocol has great advantages for improving the network performance.
