Abstract: In order to enhance data delivery ratio and reduce average delay and energy consume in Delay Tolerant Mobile Sensor Networks (DT-MSN), this paper proposes an improved Message Ferrying(MF) routing protocol named MF-MDS. It uses Minimum Dominating Set(MDS) to cluster normal nodes in the network. Simulation experiment on NS-2 proves that MF-MDS has better data delivery ratio and less average delay than traditional MF routing protocol.

摘要： 为了进一步提高容延迟移动传感器网络中的数据投递率、降低平均延迟和能量消耗，提出一种改进的Message Ferry(MF)路由协议MF-MDS。该协议采用最小支配集对网络中的普通节点进行组簇。在NS-2上进行的仿真实验证明MF-MDS在投递率和平均延迟上明显优于传统的MF协议。
