(Throughput 1 is optimal, as simultaneous reception does not increase the channel capacity.) The algorithm breaks the constant throughput lower bound for traditional radio networks, showing the power of these new hardware capabilities. We then introduce the Decodable Backoff Algorithm, a randomized backoff protocol that achieves an optimal throughput of 1 - o (1). We define the Coded Radio Network Model, which generalizes traditional radio network models (e.g., ). In this paper, we address the following question: Can we design a backoff protocol that is better than exponential backoff when exclusive channel access is not required. For example, Zigzag decoding demonstrated how a base station can decode messages sent by multiple devices simultaneously. These capabilities have now been exploited for many years by systems that rely on interference cancellation, physical layer network coding and analog network coding to improve efficiency. Modern radios, however, do not need exclusive access to the channel to communicate in particular, they have the ability to receive useful information even when more than one device transmits at the same time. For a wireless device to transmit successfully, it uses a backoff protocol to ensure exclusive access to the channel. VP of Supply Chain & Bus.Randomized backoff protocols, such as exponential backoff, are a powerful tool for managing access to a shared resource, often a wireless communication channel (e.g., ).
