Tactical data link based on OMNET++

Simulation is an indispensable link in the technical index demonstration, scheme selection and protocol design of tactical data link. OMNET++, a discrete event simulation software, is introduced in the paper as the network simulation platform in order to analyze and make statistics of important parameters of tactical data link network. Also, the key technology of the realization of data link simulation is also analyzed in the context of OMNET++. In this paper TDMA protocol simulation is realized and Link 16 data link network model is established based on TDMA protocol. In the meanwhile, according to the performance parameter simulation of Link 16, it obtained various kinds of data link network performance indexes, such as network throughput, average end-to-end delay and data packets delivery ratio. The paper also suggests that the simulation result is particularly instructive in the practical application of tactical data link.
