Abstract

In satellite networks, the design of MAC schemes which achieve high performance is an important and widely studied problem. Random access is recognized as an appealing solution for these scenarios. In the literature so far, two main research lines have been followed: diversity slotted Aloha-like protocols and spread spectrum Aloha schemes. The goal of this work is to analyze the performance of these two paradigms and introduce a hybrid algorithm which combines both packet replicas and code division to further enhance the probability of successfully decoding a packet.
