The research of performance test method of urban rail train safety detection sensor network

The paper designs a performance test method which is based on the international network test theory and the actual operation of urban rail train safety detection sensor network. With the establishment of the benchmark testing system that takes transmission delay, packet loss rate, throughput and back to back as indexes and the overall network performance test evaluation model, the performance test method proposed by the article can be used to evaluate a network that has identified network topology and protocols, and choose rational network topology and protocols when designing a network.
