%X A Priority Backoff Algorithm (PBA) for IEEE 802.11 DCF is presented in this paper. The basic idea of PBA is each station should collect statistical data of other stations' transmission while sensing the channel, and maintaining a sent data table for all stations in network. When the station has data to transmit, it will calculate contention window based on the statistical data in sent data table and its own priority. Computer simulation proves that PBA can properly assign network capacity among stations in proportion to their priorities as well as enhance the network saturation throughput.
