The lack of coordination in a multi-hop scenario complicates the analysis.
Not only the MAC protocol has to be considered but also the network topology and the channel occupation due to other nodes.
Several papers propose methods evaluating throughput for a specific network topology.
Others are not capable of evaluating a sophisticated access protocol as used by IEEE802.11, e.g. [11], or neglect the modified airtime compared to the single-hop case, e.g. [6].
