A new multi-link cooperative polling scheme

In order to improve the throughput and reduce the average delay for UAV-DL (unmanned aerial vehicle data link), a new multi-link cooperative polling scheme is proposed based on the Markov chain of flight condition for UAV-DL, Gilbert-Elliot channel model and different priorities for multi-link network. The channel state and different priorities are optimal for the multi-link cooperative polling scheme. The data is transmitted according to its channel state and priority. And then the average delay and throughput of multi-link cooperative polling model for UAV-DL are analyzed and simulated based on the probability generating function and the queuing theory. Simulation results show that the average delay is shortened by 30% and the throughput is increased 1.3 times than other ways in simulation.
