In this paper, we introduce a collision model for vehicular cluster and we propose path selection algorithms for multi-hop VANETs. That is, we propose the intuitive algorithm named range-aware broadcasting (RAB), the collisions minimized optimal path selection algorithm (CM-Opt), SNR-guaranteed optimal path selection algorithm (SNRG-Opt), low-complexity SNR-guaranteed path selection algorithm (Low-SNRG),...
In the vehicle communication system based on ADHOC network, besides fairness, QoS, hidden and exposed terminal problems, the MAC protocol must fulfill the requirement of practical applications. In order to decrease the transmission collisions in VANETs, a reliable and efficient medium access control (MAC) protocol is needed. Firstly, this paper introduces the applications, the characteristics of VANETs,...
