Self-Organizing TDMA (STDMA) is a distributed channel access algorithm
developed for position reporting in maritime and airborne domains. Its
reliability, semi-deterministic behavior, and context aware scheduling also
made it an attractive option considered by the European Telecommunications
Standard Institute (ETSI) for vehicular communications in ITS-G5.
In recent times, cellular-based Long Term Evolution (LTE) is arising as a
compelling technology to support Vehicle to Everything (V2X) communications.
While already providing vertical connectivity via the installed network,
standard extensions are being discussed to support horizontal, direct Vehicle
to Vehicle (V2V) and Vehicle to Pedestrian (V2P) communications. A
dedicated Sidelink (SL) has been defined for the purpose, as opposed to Uplink
(UL) and Downlink (DL). In this research report, we propose STDMA
as scheduling algorithm for unsupervised, low latency, direct transmissions
over SL; we highlight the challenges caused by its channel configuration,
and show its performance, which confirms its role as a valuable candidate
technology.
