Advances in vehicular communications technology are making content distribution to vehicles more effective and increasingly more popular. This paper presents state of the art technologies and protocols for content distribution in VANETs. Major challenges are Internet access spectrum scarcity, mobility, con-nectivity intermittence and scalability. Aspects(More)
—The throughput of mobile ad hoc networks subject to disruption, loss and interference can be significantly improved with the use of network coding. However, network coding implies extra work for forwarders. Selfish forwarders may prefer to simply forward packets without coding them because of the processing overhead introduced by network coding. This is(More)
Generally vehicles in VANETs should periodically broadcast safety messages. Since safety messages contain traffic related information and are sensitive to location privacy , it is essential to ensure anonymity, authenticity and traceability in broadcast. These conflicting requirements make it difficult to design a secure communication scheme for VANETs. In(More)
—Content downloading from vehicles is becoming increasingly popular, but it also meets challenges due to the limited number of roadside units (RSUs) and the expensive cost of 3G/LTE downloads. Cooperative LTE + vehicle-to-vehicle (V2V) downloading schemes can significantly improve the efficiency and reduce costs. However, selfish users are motivated to(More)
