Congestion Aware Effective Routing Protocol for Vehicular Adhoc Networks (VANETs)

Vehicular Ad-Hoc Network (VANET) is a trending concept which gathered the attention of maximum of the researchers both from the academic and industrial sector. VANETs maintains some of the eminent behaviors like rapidly changing topology, improper link connections and unpredictable mobility so that achieving effective performance among the vehicles are still in an open research area. Due to its dynamic nature attaining high Quality of Service (QoS) at the time of data transmission among the network becomes the biggest challenge. This research work introduced a novel protocol which is Congestion Aware Effective Routing Protocol (CAERPV) for vehicular networks which mainly concentrates on effective route mapping process and ACO based routing protocol. Using the effective mapping process the vehicles are properly localized with low network density. Through ACO based routing the data transmission among the source to the destination becomes more optimal that's leads to reduce of delay and power utilization in vehicles. This approach-based network model is implemented in NS2 (network simulator) to analysis its performance. The parameters which are calculated to understand the network behavior are packet delivery ratio, end to end delay, energy efficiency and routing overhead where those outcomes are connected with the earlier methods are CGQLRP and ILARPR. After analyzing the outcome it is came to know that the CAERPV method attains highest data delivery with low power utility which greatly helps to improve the network communication quality.
