Design of Trust based Context Aware RoutingProtocol in Vehicular NetworksFarhan Ahmad and Asma AdnaneCollege of Engineering and Technology,University of Derby, United Kingdom{f.ahmad,a.adnane}@derby.ac.ukVehicular Ad Hoc Network (VANET) is an active application of Mobile AdHoc Network (MANET) which aims to ensure driver safety and to provide info-tainment to the vehicular users. In VANETs, the vehicles are capable of commu-nicating with other neighbouring vehicles and road side unit (RSU). The mes-sages generated by the source vehicle is very important and in certain context,it can be very critical e.g., accident warning. Therefore, the transmission of mes-sages from source to destination is quite a challenging task. Currently, VANETsare based on traditional IP based internet architecture where the routing of mes-sages takes place only for vehicles with valid IP address. However, messages inVANETs are more important than the vehicles itself, therefore, assigning IP ad-dress to every vehicle may not be a good practice. This issue is addressed by thenew internet architecture called Named Data Networking (NDN) [1] , where thecontent (messages) plays a vital role in the network. In NDN based VANETs,vehicle can have one of the following roles [2]: data consumer, data producer,data forwarder and data mule. Data consumer generates the request, which isforwarded to the data producer via data forwarders and data mule. The dataproducer replies back to data consumer with the approval to the request.In VANETs, high priority messages should immediately be transmitted tothe vehicles in such a way that the messages received by these vehicles can betrusted. Therefore, this study propose the concept of Context Aware RoutingProtocol (CARP) in NDN based VANETs which aims to transmit trusted in-formation in a secure and reliable way. CARP considers different scenarios, andit ensure to transport the message as soon as possible in a highly secured andtrusted environment. CARP takes the Quality of Service (QoS) of applicationsinto account which makes it a highly efficient routing protocol. The protocol isdesigned such that it supports the traditional NDN Daemon in every vehicle,consisting of NDN data structures and forwarding strategies, and implementrules to check the trustworthiness of messages.References1.
