Abstract
AbstractIonized trails caused by the entry of meteors into the atmosphere provide probabilistic communication paths between two points over the horizon. Three protocols for a data collection system via meteor burst communication channels are studied and evaluated. the first is merely the pure ALOHA protocol applied to the probabilistic channel. the second is called the IT protocol. It has a frequency division idle‐tone channel. A terminal which has a message observes this channel and determines whether the main channel is open or closed for it. the third protocol, the so‐called ITT protocol, also has idle‐tone channel. Messages are divided into many blocks (this message structure is called “Tokage (lizard)” type) and go‐back‐N ARQ protocol is utilized. We show that the idle‐tone and the lizard‐type message with ARQ, are extremely effective to increase the channel utilization in such systems. It is also shown that high channel utilization can be achieved by the use of the ITT scheme even in a probabilistically generated and terminated communication channel such as meteor burst communication path.
