In the performance test of mesh network routing protocol, it is found that BATMAN. Adv routing protocol has better performance than the existing multi-hop routing protocol, but it also has the defects of poor routing convergence and slow response to network topology changes. Based on the detailed analysis of BATMAN. Adv routing protocol, this paper proposes an improved method. First, the statistical method of OGM package was redesigned, the cumulative sliding window method is used to improve the influence of the latest serial number of OGM, and the calculation method of TQ value is changed from average accumulation to weighted accumulation to further improve the influence of the latest TQ value. At the same time, an improved mechanism is proposed in order to solve the problem of link blocking caused by sudden node failure. Finally, through simulation experiments, the performance of the packet delivery rate and end-to-end delay of the three routing protocols in two different scenarios is compared. It shows that the improved protocol can effectively improve the packet delivery rate, reduce the average end-to-end delay, and improve the network performance.
