The probability distribution characteristics of multi-hop transmission between the sending node and the destination node are analyzed under the uniform distribution of node locations. Under the Gupta signal-noise ratio interference model, the closed expressions of the upper and lower bounds of multi-hop network capacity are deduced and the network capacity is numerically simulated. The following conclusions: The probability of information multi-hop transmission in the network is higher than the probability of single-hop transmission. The capacity of multi-hop network increases first and then decreases with the increase of the number of nodes. The multi-hop feature of the network is beneficial to improve the network capacity.
