Abstract: Vehicular network always suffers from the issue of heavy traffic and load that increases the communication delay and loss. In this paper, a multi level prioritization method is applied within the existing GPSR protocol for effective route generation and improving the functionality of vehicular network. The proposed model is divided in two sub stages. In first stage, the prioritizations to the vehicle nodes are assigned. The priority assignment is done based on the role, behavior, communication characteristics of vehicle. Once the priorities are assigned, the communication is performed in the network. The rules are defined for considering the priority nodes as the intermediate node or not. The proposed prioritization based communication model is also sensitive to unbalanced load and network attack issue. Based on these considerations, the vehicle priority can be changed. The proposed protocol is defined as an improvement to GPSR protocol. The proposed work is simulated in NS2 environment. The simulation results show that the improved protocol enhanced the packet communication and reduced the packet loss and communication delay effectively.
