%X Aiming at the problem of signal collision in the dense Internet of Things environment, an anti-collision broadcasting scheme was proposed which can group respond to multiple nodes in time and reduce the collision rate. The collision probability was analyzed by multi-period iteration, and a theoretical model was established which effectively solves the serious channel collision in concurrent broadcasting of large-scale sensor nodes. Monte Carlo simulation was created to evaluate indicators such as latency, capacity, and power consumption. The key parameters affecting the performance were analyzed. The model calculation results are consistent with the simulation results. Compared with the unresponsive broadcasting protocol, the broadcast response mechanism can effectively confirm, reduce 23% network delay and 90% broadcast collision, and increase the system capacity by 100%.
