水声传感器网络中一种基于多种群萤火虫的路由协议

Multi-population Firefly Based Routing Protocol in Underwater Acoustic Sensor Networks

针对水声传感器网络的特殊性,提出一种基于多种群萤火虫的路由协议,以确保数据包在水声传感器网络各节点之间正确、高效地转发。首先构造水声传感器网络的网络模型;然后,设计3种类型的萤火虫,通过各种萤火虫之间的协同工作提高路由路径构建的自适应性并实现路由路径的选择和优化。仿真实验结果表明,与传统的水声传感器网络路由协议相比,在节点数量相同情的况下,该路由协议的数据包传送率更高,平均端到端延时更低,并且在平均数据传送率相同情况下,网络吞吐量更大。

Considering the unique characteristics of underwater acoustic sensor networks （UWASNs）,this paper pro- posed a Multi-population Firefly based Routing （MFR） protocol to ensure that data packets can be correctly and effi- ciently forwarded in UWASNs. Firstly, we presented the network model of our UWASNs. And then, we designed three kinds of fireflies and their coordination rules in order to improve the self-adaptability of building, selecting and optimiza- tion of routing path. We demonstrated through simulations that our routing protocol outperforms traditional protocols in packet delivery ratio,end-to-end delay and network throughput under the same circumstances.
