Seamless Communication to Mobile Devices in Vehicular Wireless Networks

Abstract

Vehicular networks are deployed as hybrid networks, which consist of a cooperation of different radio access networks. Seamless communication in vehicular networks relies on proper network planning and thorough dimensioning of network protocols. Both are assessed and verified by simulation. In transportation networks, the location of the mobile devices and their pattern of movement are very important. Therefore, different mobility models suited to vehicles in transportation networks are introduced. Then, the need for location information is exemplified. Mobility models and location play an important role in the verification of handover protocols. One hybrid handover protocol is given in detail. It provides low handover latency with additional mutual authentication to allow the transfer from one radio access network to another while maintaining the network's built-in security standard. This protocol is easily extensible to include a broad variety of networks.
