Research on dynamic polling network access control protocol based on priority

This paper analyzes the polling principle of IEEE802.11 PCF, and researches on the key parameters such as the system of the average queue length and average waiting time. In this paper, it presents a new dynamic polling access protocol based on priority (DPQWMAP protocol). The simulation results show that the protocol reduces the average waiting time of the whole system by the cluster head dynamically select the highest priority nodes.
