This chapter will tackle one of the most important disadvantages that will take place in the Vehicular Ad Hoc Network during a crisis scenario. Vehicular Ad Hoc Network which is abbreviated as VANET is a variation of Mobile Ad Hoc Network (MANET). VANET routing protocols are a wide research area due to their different classifications with the pros and cons of each. This chapter will summarize the five VANET routing protocols categories. The common criteria among those five-routing protocols are the requirement of infrastructure which is also known as a road-side unit (RSU) or base station (BS). The role of the RSU is to provide an internet connection. Packets will be uploaded to the RSU which will, in turn, be uploaded to the internet thus making them available for future download. In a crisis scenario, one or more RSU might be disconnected from the internet which will result in a disconnected network. The disconnected network will lead to the failure of packet upload and time out leading to loss. This chapter will propose a protocol to ensure a successful packet delivery with a disconnected RSU from the internet. The network is considered as a set of sensors that periodically upload data to the RSU which in turn uploads them to the internet. The sensors might be those of Wireless Sensor Network (WSN) or onboard sensors. The proposed protocol will take into consideration that vehicles are assumed to be capable of short-range wireless communication and hence can collect data from a nearby RSU. The main target of the proposed protocol is to ensure a successful data transfer during the time a certain vehicle known as the carrier vehicle is within the communication range of a road-side unit. A simulation carried in MATLAB studied the different effects of network parameters on the successful data transfer from the disconnected RSU to the carrier vehicle.
