摘要: 针对低工作周期的无线传感器网络存在数据成功传输率低的问题,提出一种基于洪泛的数据传输机制,即多重洪泛机制(MF)。使用MF 时网络中节点在有数据需要发送时,会尝试洪泛K 次数据,洪泛次数K由网络需要的成功传输概率决定。仿真实验结果表明,引入多重洪泛未大量增加网络中传输数据分组的数量,节点能耗相比传统的路由算法没有明显增加,同时减少分组的传输时延,提高了分组成功传输的概率。

Abstract: A novel data transmission mechanism based on flooding for low-duty-cycle Wireless Sensor Network (WSN),named Multi-flooding(MF) is proposed. Using MF,the node which has data to send will keep trying to flood the data to its destination for K times,while K depends on the required successful transmission ration. Simulation results show that MF with limited times does not generate much more broadcasting packets and energy consumption compared with other routing protocols, but reduces the transmission delay and increases the successful transmission ration remarkably.

Key words: Multi-flooding(MF), low-duty-cycle, Wireless Sensor Network(WSN), flooding times, node energy consumption
