Mobile IP Handover for Vehicular Networks

Abstract

The popularity and development of wireless devices has led to a demand for widespread high-speed Internet access, including access for vehicles and other modes of high-speed transportation. The current widely deployed method for providing Internet Protocol (IP) services to mobile devices is the mobile IP. This includes a handover process for a mobile device to maintain its IP session while it switches between points of access. However, the mobile IP handover causes performance degradation due to its disruptive latency and high packet drop rate. This is largely problematic for vehicles, as they will be forced to transition between access points more frequently due to their higher speeds and frequent topological changes in vehicular networks. In this article, we discuss the different mobile IP handover solutions found within related literature and their potential for resolving issues pertinent to vehicular networks. First, we provide an overview of the mobile IP handover and its problematic components. This is followed by categorization and comparison between different mobile IP handover solutions, with an analysis of their benefits and drawbacks.
