An Optimized Node Selection Routing Protocol for Vehicular Ad-hoc Networks – A Hybrid Model

Abstract

Vehicular Ad-hoc networks (VANETs) are a subset of Mobile Ad-hoc Networks made by vehicles communicating among themselves on roadways. The Routing protocols implemented for MANETs such as Ad-hoc on Demand Distance Vector Routing Protocol (AODV), Dynamic Source Routing (DSR), and Destination Sequence Distance Vector Routing Protocol (DSDV) are not suitable for VANET due to high Mobility. Trusted routing in VANET is a challenging task due to highly dynamic network topology and openness of wireless architecture. To avoid a frequent communication link failure, to reduce the communication overhead and to provide a trusted routing among the vehicular nodes for achieving high packet transmission, we implemented an Optimized Node Selection Routing protocol (ONSRP) of VANET based on Trust. In our proposed work, we implemented an enhanced routing protocol which prevents the network from communication link failure frequently. The testing results stated that the ONSRP routing have a high performance measures than the above mentioned existing routing protocols.
