Research on Data Transmission Optimization Of Communication Network Based on Reliability Analysis

Firstly, this paper briefly introduces the vehicular communication network, vehicular ad-hoc network (VANET), and the ant colony algorithm for path search in the network. Then the ant colony algorithm is improved. A simulation experiment is carried out on the improved ant colony algorithm on the simulation platform, and it is compared with the traditional ant colony algorithm and the geographical locationbased routing algorithm. The results show that the network packet loss rate and time delay show a tendency of increasing first and then decreasing under the three algorithms with the increase of vehicle nodes in VANET; with the increase of nodes, the network reliability under the improved ant colony algorithm shows a tendency of increasing first and then being stable, and the network reliability under the other two algorithms shows a tendency of increasing first and then decreasing; under the same number of nodes, the packet loss rate and average delay are lower, and the reliability is higher under the improved ant colony algorithm.
