Aiming at analyzing the influential factors of WSNTS errors and revealing the distribution laws,this paper established the mathematical model of WSNTS errors,and pointed out that the one-hop WSNTS errors also met normal distribution under the condition of considering all the time delays,and also gave the random process model of the multiple hops for the maximum errors of WSNTS and its expectation,variance and the upper and lower limit through analyzing the TPSN algorithm based on two-way message switching mechanism.Theoretical proof and simulation experiments show the correctness of these results.It provides a theoretical basis for the design and analysis of WSNTS mechanisms.
