Binary exponential backoff (BEB) algorithm, the de-facto standard contention resolution algorithm providing collision avoidance over ad hoc wireless networks, has several technical limitations. For instance, high collision rate problem, unfair channel access, and throughput degradation are several widely known issues. In this paper, a self-adaptive backoffalgorithm, namely slowstartbackoff (SSB) algorithm, is proposed and analyzed for ad hoc networks. Numerical results show that the proposed SSB algorithm outperforms the legacy BEB algorithm. In addition to the theoretical analysis, simulations were conducted to verify the analysis, showing that the proposed scheme works very well in ad hoc wireless networks.
