Abstract
The demand for real-time applications such as short video clips of CCTVs on a roadway, raises the need of for seamless and ubiquitous Internet connectivity in vehicular networks. Wireless Access in Vehicular Environment (WAVE) architecture defines the IPv6 mobility protocols to be deployed in network layer. However, the Current IP mobility management protocols, including Proxy Mobile IPv6 (PMIPv6), employ a centralized and single anchor to register MU's location information and establish communication which causes excessive burden on that central anchor. Recently, Distributed Mobility Management (DMM) based on PMIPv6 has been introduced to overcome these problems. In this paper, we investigate the vehicle velocity effect in urban environment where a map within the city of Bangi is taken. We compare the handover performance of network-based DMM with PMIPv6 in aspects of handover latency, session recovery, packet loss and throughput. The results show that network-based DMM outperforms PMIPv6 slightly.
