Simulation of MAC Protocol in Near Space Communication Network Based on TDMA

A network model for the near space communication network is established by the means of OPNET as a development environment, and a medium access control (MAC) protocol based on TDMA (time division multiple access) is designed, leading to the channel resource being shared efficiently. A formula for the average end to end (ETE) delay of the network is delivered according to the queue theory. Simulation results show theoretic analysis can accurately estimate the average ETE delay of the network.
