Reliability evaluation of a communication network with Transmission Distance Constraint

Considering transmission distance constraint, a reliability evaluation method is proposed to evaluate the data transmission capability of a communication network in an uncertain environment. Network reliability is defined as the probability that the amount of data transmitted by the network can meet the requirements of devices when each edge has random transmission capacity and there is a limit on the transmission distance. By utilizing the concept of the minimal path, a reliability model based on minimal capacity vector is established, and an effective calculation method is designed. Finally, the results of numerical experiments show that the data transmission distance has a significant impact on the reliability of a communication network, and this impact is even greater under high demand levels.
