Reducing transmission interferences for safety message dissemination in VANETs

In this paper, we study the problem of efficient safety message dissemination in Vehicular Ad-Hoc Networks (VANETs). The objective is to reduce vehicular communication interferences for safety message delivery while guaranteeing the timeliness and the reliability of messages to avoid accidents. Therefore, we propose a heuristic algorithm called Time-Limited Reliable Broadcast Incremental Power (TRBIP) to construct a safety message delivery tree. Extensive simulation results show that the proposed algorithm outperforms its counterparts in terms of message timeliness, reliability and interference reduction.
