| Abstract: | Long distance ad hoc network communication technology can be adopted to realize train-train communication for heavy-haul train.Based on TDMA principle,this paper establishes models aiming at the probability of frequent-point resource collision between one-hop nodes in ad hoc network,and puts forward the calculation method for air interface collision probability of heavy-haul railway MESH ad hoc network communication node.Through the key parameter setting,the system collision probability between one-hop nodes can be calculated,and by using Monte Carlo method,the statistical simulation verifi cation in MATLAB will be performed,which have guiding signifi cance to system design and engineering design optimization. |
