IP address allocation protocols in vehicular ad hoc networks

“…• Scalability: As the network expands, the time required to obtain an IP address or the number of overhead packet exchanges should not increase. 15 • Security: A major challenge is to prevent security threats that are related to the address allocation protocol of VANETs. 16 Vehicles can also communicate with a different vehicle.…”

“…Therefore, in this type of network, a distributed technique is a great option for powerfully obtaining a dynamic address from the network 14 . Subsequently, for assigning out an IP address in VANETs, a standard IP addressing protocol has following objectives: Uniqueness: The protocol must allot IP addresses in VANETs for accurate selection of route and for uni‐casting communications. Robustness: The addressing protocol must adjust to the network's dynamics, such as merges and partitions. Reliability: The possibility of node address conflicts due to joining and partitioning should be as low as possible. Scalability: As the network expands, the time required to obtain an IP address or the number of overhead packet exchanges should not increase 15 Security: A major challenge is to prevent security threats that are related to the address allocation protocol of VANETs 16 …”
