Architecture for Decentralized Mitigation of Local Congestion in VANETs

The limited communication resources in VANETs have to be used efficiently to achieve reliable communication even in high load situations, where high packet loss is expected. Packet loss can occur on the channel or it occurs in the local queue due to a saturated channel. In this case, information becomes outdated and hence can be dropped. In this paper, the authors propose multiple steps to solve this problem. They establish a model that determines the network capacity and the influence of hidden stations. The state of overloading the channel beyond the network capacity is named local congestion.
