Abstract: The low delivery rate and large network overhead is of great challenge in the apron-aware network scenario. To solve the problem, an opportunistic transmission control method (OTCM) based on game theory is proposed. First, combining the characteristics of the scene to establish the initial-pass node game model to achieve message transmission sequencing and the problem of transmission priority is solved. Then a game rule system and function is planned that integrates multi-dimensional topology node attributes to achieve the optimization of the message transmission environment and the reliability of the transmission process. At the same time, according to the utility function in the game system, the topology can be adaptively updated after adding the new opportunity node. Hence the topology maintains its optimal state. Using opportunistic network environment to establish a domestic apron scene simulation. Verification shows that the OTCM algorithm has an average delivery rate of 52.50% and an average transmission delay reduced to 1 773 s compared with other opportunistic routing strategies, which basically meets the research goals.
