Euler spiral based backoff algorithm for MAC protocol in mobile Ad Hoc networks

Researchers have developed different backoff algorithms to help boost how well IEEE 802.11 distributed coordination function (DCF) performs. The standard approach, known as binary exponential backoff (BEB), is commonly used, but alternatives exist. One alternative that has gained attention is the Fibonacci incremental backoff (FIB), mainly because it is shown to be quite effective. This paper introduces a novel backoff method that’s inspired by the Euler spiral curve. To assess its performance, we performed simulations comparing the proposed approach with both BEB and FIB. We focused on key performance measures like network throughput and end-to-end delay, particularly in mobile ad hoc networks. The results are encouraging: our method delivers better throughput than both BEB and FIB. However, it does come with a trade-off. It does exhibit slightly higher end-to-end delay compared to FIB.
