Throughput - Delay Characteristics of Some Slotted-ALOHA Multihop Packet Radio Networks

A Markovian model is formulated to find the throughputdelay performance for slotted-ALOHA multihop packet radio networks with a fixed configuration of packet radio units (terminals and repeaters) and fixed source-to-link paths for packets. Improvements in performance which are obtained by the adjustment of transmission parameters (suppression/acceleration) according to the states of nearby units and/or by having repeaters equipped with multiple buffers are demonstrated.
