Time-Sensitive Network Simulation for Multi Marine-Air Platforms Basing on SPMA Protocol

摘要

To meet the low delay transmission requirement for “time sensitive” business under the condition of large network load in battlefield environment, a kind of mobile ad hoc network system based on SPMA protocol is studied. Multi marine-air platforms confront scenario with message, voice and video business service running is molded with OPNET software, and the simulation is implemented to obtain the network parameters like throughput, traffic dropped and network delay under different transmission priority or backoff strategy. Results show that, the “time sensitive” network can still archive low delay business transmission under heavy network load that three kinds of business are running at the same time, and it can be further reduced when back-off services number is increased.
