Simulation and Performance Analysis of Bridge Monitoring System

Network simulator version 2 (NS2) is used to simulate the bridge monitoring system, and the simulation results are analyzed. The impact of performance evaluation has no unified standard. Based on the simulation of transmission delay, delay jitter, and so on, the advantages of the three routing protocols are compared to explain different bridge environments through comparison. The analysis results show that in the Ad hoc on-demand distance vector routing (AODV) of the delay, bandwidth is more sensitive to a greater degree of destination-sequenced distance vector (DSDV) and dynamic source routing protocol (DSR), which is determined by the characteristics of the routing protocol. The process of establishing a route before each data transmission requires a certain bandwidth, so in the case of insufficient bandwidth, a time delay is significantly larger than that of DSDV and DSR in the resource. Then, the routing setup process becomes significantly faster, and the three routing protocols become close to delaying.
