Vehicular ad hoc networks (VANETs) are a growing research area primarily on efficient routing protocol design with foreseen applications including safety, traffic and infotainment services. VANETs are the promising technology to enable the communication between nodes in rural areas rather in urban areas and hence it is a challenging task to establish a routing reliability in partially connected environment with privacy and security which characterize to be a delay tolerant network. In this paper we examine the challenges of VANETs in partially connected networks using Border node Based Routing (BBR) protocol where the protocol achieves high routing reliability at low node density and high node mobility. Path discovery algorithm is proposed between the communication points with secret key generation for secure transmission. Simulation results with ns2 reveal interesting insights and trade-offs related to packet delivery ratio and packet delays for partially connected networks.
