Abstract

The paper proposes a mobility handover scheme MHVA for IPv6-based vehicular ad hoc networks. In MHVA, a vehicle is uniquely identified by its home IPv6 address, and it can keep the communication with other nodes without a care-of address during the mobility process. In addition, MHVA adopts an advanced mobility handover mechanism where the mobility handover operation in the network layer is completed before the one in the link layer is performed. As a result, during the advanced mobility handover process, a vehicle can keep the connection with its current associated AP in the link layer, so it can receive the data forwarded by the AP. Therefore, the packet loss rate is reduced, the mobility handover cost is decreased, and the mobility handover delay is shortened. From both the theoretical perspective and simulative perspective, the performance parameters of MHVA are evaluated, and the data results show that the mobility handover cost of MHVA is lower and the mobility handover delay is shorter.
