Abstract:

Being a subclass of mobile ad hoc networks (MANETs), vehicular ad hoc networks (VANETs) have received considerable attention in recent years. Existing routing protocols of MANETs do not perform well for VANETs due to many different characteristics such as, fast moving nodes and frequent disconnections in the network. We present a context-aware hierarchical routing protocol based on road connectivity and vehicle context in VANETs called Context-aware Two-level Hierarchical Routing (CTHR) designed to fulfill QoS requirements in inter-vehicle communication in both urban and highway environments. CTHR's distinguished property is to not only find the available paths between source and destination but also to select the best available path based on QoS parameters. QoS parameters are calculated using the vehicle context such as, velocity. Unlike other routing protocols, the path from source to destination is made by road id's. CTHR uses gateway vehicles to locate the destination, forward the packets and to calculate QoS parameters. For the evaluation of CTHR protocol, we perform extensive simulations and results show that CTHR can help in design and deployment of VANETs.
