Precise configuration of mixed message sets' transmission mode in network partition

It was indicated that configuration of message transmission mode among network partition method in distributed integrated modular avionics was uncertain. Through formal description the problem was transferred into an optimal problem with constrains including real-time, bandwidth and buffer. Then the transmission mode configuration algorithm was proposed based on genetic simulated annealing algorithm; the objective function was aimed to balance of end-to-end delay of system messages. Effectiveness of the algorithm was verified based on two experiments, and performance of the algorithm was compared with that of traditional genetic algorithm. The results show although the algorithm is 18.1% slower, the fitness value is 28.7% higher. This algorithm provides a reference for the network partition application in avionics systems.
