End-to-end Delay Assessment and Hybrid Routing Protocol for Vehicular Ad Hoc Network
Le Van Minh, Yang MingChuan, Qing Guo · IERI Procedia · 2012
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 we concentrate on measurement end-to-end delay in VANET, and using these results for building route metric with the aim of shrinking route discovery time. For deploying route model we use hybrid routing protocol (combined between proactive and reactive routing protocol) aiming reduce route overhead, accelerate route convergence speed, and enhance route quality in routing table in each node. The simulation results illustrate prominent features of our proposed model.
