A cooperative and fully-distributed congestion control approach within VANETs
Mohamed Salah Bouassida, Mohamed Shawky · 2009
Appropriate congestion control mechanisms are essential to maintain the efficient operation of a network. Ensuring congestion control within vehicular ad hoc networks address special challenges, due to the characteristic and specificities of such environment (High dynamic and mobility of nodes, high rate of topology changes, high variability in nodes density and neighborhood, broadcast/geocast communication nature ...). In this context, we present in this paper a cooperative and fully distributed congestion control approach, based on the concept of dynamic priorities-based scheduling and transmission, to ensure a reliable and safe communications architecture within VANET. The real applicability of our congestion control approach is validated through its formal verification and performance evaluation.
