A task model for TDMA communications

In this article a new task model, called DGMF, is proposed to improve scheduling analysis of dependent tasks in radio stations that embed a TDMA communication protocol. TDMA is a channel access protocol that allows several stations to communicate in a same network, by dividing time into several time slots. This protocol has an impact on task release times, execution times, and deadlines, which needs to be considered for less pessimistic scheduling analysis results. We experiment on software radio protocols from Thales, which are representative of the system we want to analyze.
