Traffic Interference Analysis and Resource Allocation Scheme for Wireless Local Area Networks with Infrastructure Mode

In this paper,the influence of wireless channel state transformation in wireless local area networks with infrastructure mode is studied.It is shown that the interference among different traffics will lead to severe performance degradation of all downlink traffics. A novel channel state aware resource allocation scheme is proposed,which adaptively adjusts transmission limit for different traffics based on the state of wireless channel and schedules packets using a priority algorithm according to the QoS requirements of the traffics.Experimental results show this scheme can allocate resource more efficiently and reduce the performance degradation caused by the interference of downlink traffics.
