... Exponential Fade Duration. We assume arbitrary distributions for both nonfade and fade durations. As a special case, we consider fixed l for nonfade duration and exponentially distributed fade duration ... leading to even lower efficiency. Hence, the exponential backoff of IEEE 802.11 is unsuitable for such ad hoc forwarding of packets, which is also shown in [36]. Lastly, the fading ch...
