Abstract

Aiming at the problem that the routing metric selected in the research of routing protocols in the existing literature fails to combine the performance level of the UAV self-organizing network at that time and results in unreasonable routing decisions, this paper proposed a multi-indicator and multi-path optimized link state routing protocol with load awareness and network topology change awareness. Firstly, the proposed protocol considered the mobility characteristics of nodes and the lifetime of the network in the UAV scene, and defined three indicators for routing, namely the node's MAC layer blocking degree, the node's neighbor change rate and the number of MPR_S neighbors of the node. Secondly, combined with HELLO and TC control messages, this paper proposed an indicator notification mechanism to flood the indicator information to the whole nodes of the network. Finally, according to the indicator information, this paper proposed a multi-path routing scheme. The simulation results show that compared with OLSR, SETT_MPOLSR and UAV-OLSR protocols, the proposed MIMP-OLSR protocol significantly improves success rate, end-to-end delay and throughput performance, which further proves the rationality of the proposed multipath routing scheme.
