Research on MAC protocol of polling system based on blockchain

To solve the problem of the expansion of network information transmission and the reduction of data transmission efficiency, a MAC protocol that combines blockchain and polling system is proposed. First, the polling system model based on blockchain is studied, and its data distribution method is analyzed. Then the theoretical expressions of the average queue length, the average waiting time, and the average cycle period of the Gated, the Exhaustive, and the Limited-K service system are derived. Finally, the theoretical value and the experimental simulation value are compared and analyzed by Matlab. The results show that with the increase of the arrival rate, the polling system after joining the blockchain improves the efficiency of information transmission. A comprehensive comparison of the experimental results, based on ensuring fairness, the Gated service system is more stable than the other two service strategies in accelerating information processing speed and improving system performance.
