Collision Rate Adaptive Binary Priority Countdown protocol

In the previous work, binary contention protocol, called Binary Priority Countdown, BPC, was introduced. The BPC has the ability to manage the priority space without the need to change the length of the binary countdown round. In this work, we present a development of a new adaptive algorithm, called Collision Rate Adaptive Binary Priority Countdown, CR-ABPC, that can optimize the usage of priority space of the BPC protocol based on the collision rate. When the number of active stations increases, the new CR-ABPC protocol adjusts the priority space accordingly, in order to enhance the network throughput. The throughput increase of adaptive algorithm is verified using the network simulator ns2.
