DCF Based on Packet Priority and Its Performance Analysis
Shunfu Jin · Jisuanji gongcheng · 2009
Aiming at the different QoS requirement of real-time affairs,considering the priority of packet,and based on the classical Distributed Coordination Function(DCF) and several modified DCFs,this paper presents a Packet priority-based Modified Distributed Coordination Function(PMDCF).It uses the method of Markov chain to analyze the performance of PMDCF and gets the formula of saturation throughput for the system.Numeral example and simulation results show that compared with existing DCFs,PMDCF can effectively improve the system performance.
