Abstract:

To satisfy the requirements of the QoS in the wireless network,three classical priority queue scheduling algorithms are discussed in this paper,namely Round Robin (RR),Priority Queuing (PQ),and Proportional Fairness (PF).The principles,advantages and disadvantages of the three algorithms are studied,and finally a practical one is chosen through computer simulation.
