一种基于聚类算法的ETX辅助无人机AODV路由协议
An ETX assisted unmanned aerial vehicle AODV routing protocol based on clustering algorithm
摘要
Abstract
In order to ensure stable information transmission in flying ad hoc network(FANET)under rapid topology changes,based on the ad hoc on-demand distant vector(AODV)routing protocol with expected transmission count(ETX)metric,a K-means clustering algorithm based on K-AODV-ETX routing protocol was proposed.Three clustering features,hop count to destination node,number of error transmissions,and node buffer space were used in the protocol to classify UAV nodes,the best clusters for route discovery were selected when RREQ packet forwarding,and finally the ETX mechanism was used to select the path with the smallest ETX value and for data transmission.The results show that after NS3 simulation analysis,compared with the existing AODV-ETX routing protocol and ND-AODV-ETX routing protocol,K-AODV-ETX routing protocol is able to maintain the throughput of the network effectively,with a slight degradation in end-to-end packet delivery rate performance,and a significant effect in terms of routing overhead and delay performance.K-AODV-ETX routing protocol optimizes the route discovery process with the flood broadcast mechanism,which effectively improves the high overhead and high latency problems of the existing protocols under the ETX mechanism and ensures the throughput of the network.The research provides an effective method for designing low-latency routing protocols and balancing the high overhead problem brought by the ETX mechanism.关键词
