The Intelligent Transportation System (ITS) addresses issues regarding traffic management and road safety in the domain of Vehicular Ad hoc Networks (VANETs). With the evaluation of new applications, new goals regarding efficiency and security are added for logistics and general user application, which demand time bounded and reliable services. In this paper, we discuss VANET with regards to its suitability in logistics scenarios, challenges to cope with high mobile vehicles and their short contact duration to meet the goal of efficiency. Although VANET helps to provide efficient solutions for logistics and transportation, there are still number of issues to be solved to obtain an appropriate solution. In the context of increasing number of vehicles, high bandwidth requirements for applications, and highly dynamic topology, route optimization and efficient security mechanisms requires special attention. To this regards, a number of routing protocols have been proposed, yet each routing protocol focuses on traditional topological based routing protocols. The selection of the routing methods depends upon the nature of the networks. Number of researchers argued that the most of the routing protocols focus on the particular scenario and consider particular factors for evaluation such as type of network, mobility pattern, and Quality of Service (QoS) requirements for applications. Thus, the performance of the routing protocols depends upon the particular scenario. In this paper, we focus on designing a routing protocol framework, which can provide a reliable and efficient solution for the path selection by considering different factors from application scenarios like logistics and transportation using varying parameters such as speed, number of wireless nodes, traffic loads and bit error rate. Furthermore, we consider channel parameters for the routing protocols to render the communication to be reliable. For proof of concept, we provide and discuss basic simulation results of our proposed framework.
