Abstract
The stations that use a shared medium like IEEE 802.11 wireless LAN have transmission opportunities by contention in the contention period. If there are collisions in the contention period, a medium access control protocol may solve collisions by using a backoff algorithm. The backoff algorithm is an important part of the medium access control protocol, but a legacy backoff method used in IEEE 802.11 standard is not efficiently adjusted depending on the load condition and priorities. In this paper, we propose a new load-based dynamic backoff algorithm to improve throughput of medium and to reduce the number of collisions. The proposed backoff algorithm can increase network utilization about 20% than that of the binary exponential backoff algorithm.
