Research of updating strategy using WIFI network for multimedia files in bus system

In order to meet the updating strategy requirements in the bus systems by WIFI network, the optimized ant colony algorithm is proposed in the updating application of multimedia files in bus system. Firstly, the existing problems of the updating strategy are illustrated and the mathematical model of the updating strategy is established. Then the algorithm is constructed based on the ant colony system. Through the analysis of the feasible solution problem, the vehicle updating sequence which makes the multimedia files updated efficiently is achieved. The simulations on matlab are also carried out. Finally, it is demonstrated that the optimized ant colony algorithm is well applied in the updating strategy of multimedia files for the bus system.
