Load Statistics Priority Random Access Technology Based on Air-Space-Ground Integrated Network
In today's world where everything is interconnected,air-space-ground integrated net-works have become a current research hotspot due to their characteristics of high,long and wide area coverage.Given the constantly changing and dynamic characteristics of air and space net-works,along with the sheer number and complexity of access nodes involved,the process of rapid networking presents substantial challenges.In order to achieve rapid and dynamic networking of air-space-ground integrated networks,this paper focuses on the study of methods for large-scale nodes to randomly access satellites.This paper utilizes a cross-layer design methodology to enhance the access success probability by jointly optimizing the physical layer and medium access control(MAC)layer aspects.Load statistics priority random access(LSPRA)technology is proposed.Experiments show that when the number of nodes is greater than 1 000,this method can also ensure stable access performance,providing ideas for the design of air-space-ground integrated network access systems.
