Adaptive location based TDM protocol for inter-vehicle communication
Recently, in order to avoid traffic accidents, several studies using inter-vehicle communication have been proposed. This paper proposes a slot allocation protocol which allocates TDM slots based on location information of running vehicles. The proposed protocol allocates a slot for each coordinate in advance. To improve efficiency of slot utilization, each vehicle collects the location information of its surrounding vehicles, calculates which slots can be used for avoiding occurrence of reception errors and selects a suitable slot autonomously. Moreover, it uses backoff in each slot to decrease collisions, and notifies collisions and unused slots in leftover backoff time. Through the simulation, we show its performance and effectiveness.
