Abstract: Abstract With the development of information technology, more and more devices need to access the network. Contention-based Media Access Control (MAC) protocol can better adapt to the changes in network topology and is widely used without complex synchronization and control scheduling algorithms. In the system using contention-based MAC protocol, as the number of access channel nodes increases, severe conflicts and collisions occur when the nodes compete for the channel, leading to a severe decline in system resource efficiency. This paper proposes an improved contention-based MAC protocol DCF* based on IEEE 802.11 distributed coordination function(DCF), which reduces the number of competing nodes and effectively enhances the system resource efficiency by adding the information maintenance of neighbor nodes. The relationship between system delay, system resource efficiency, and back-off parameters, neighbor maintenance times of the two protocols are simulated under the same node scale, and the resource efficiency of the two protocols is analyzed and compared with the increase of the number of nodes in the network. The results show that the resource efficiency performance of the DCF* protocol is better than that of the DCF protocol.
