Abstract:
The basic concept of slotted ALOHA as a Random Access Protocol (RAP) is commonly implemented for ubiquitous access in many wireless networks. In this paper, we study the generalization of the network control by Bayesian broadcast to the environment of M -MRP Multiple Packet Reception (MPR) when channel impairments are considered. In our M -MPR model, up to M data packets transmitted in the same time-slot can be correctly decoded by using capture effect and some advanced signal processing techniques such as Successive Interference Cancellation (SIC) combined with Multiple-Input Multiple-Output (MIMO). We show that the broadcast or permission probability that maximizes the throughput (packets per slot successfully transmitted) is sensitive to channel characteristics. While with ideal channel conditions of maximum capacity a binary feedback – collision versus non-collision – is required, and in the more realistic channel conditions, M + 1 feedback is needed.
