摘要：VANETs have particularly important applications in sparse and rural areas because of the lack of fixed communication infrastructure. In rural areas, vehicle densities are low and roadway communication infrastructure is scarce, leading to long periods where vehicle-to-vehicle or vehicle-to-roadside communications is infrequent, interrupted, or simply not possible. Channel between vehicles is necessary for realistic modeling of VANETs and the development of related technologies and ap plications. The applications range from safety and crash avoidance to Internet access and multimedia. These include frequency allocation, standards for physical and link layers, routing algorithms. Routing algorithms appropriate for these circumstances have been less explored and the design of such a routing protocol is challenging. In this paper, we examine a range of VANET routing protocols and describe their associated issues and various approaches to resolve them. The comparative study is mainly done on the essential characteristics and behavior of the protocols
