The moving with fast velocity of each node in Vehicular Ad hoc NETwork (VANET) results in the existence transient communication links, which degrade the performance of developed protocols. Established routes frequently become invalid, and existing communication flows are interrupted, incurring delay and additional overhead. In this paper, the authors use cross layer approach solving these problems. Firstly, they concentrate on measurement end-to-end delay in VANET. Subsequently, they use the end-to-end delay assessment of Medium Access Control (MAC) layer for building route metric in network layer with the aim of shrinking route discovery time.
