Broadcasting in Connected and Fragmented Vehicular Ad Hoc Networks

Table 1

Comparison of broadcasting protocol in VANETs.

Existing protocol	Network scenario	V2V/V2I	Node selection parameter	Mechanism for network fragmentation
IVG	Highway	V2V	Distance	Periodic broadcast
DRG	Highway	V2V	Distance	Periodic broadcast
DV-CAST	Highway	V2V	Distance	Store carry forward
MobiCast	Highway	V2V	Distance	Store carry forward
SRD	Highway	V2V	Distance; Direction	Store carry forward
EAEP	Highway	V2V	Random	Epidemic
UV-CAST	Urban	V2V	Distance, angle	Store carry forward
EDB	Urban	V2I	Distance	Repeater
Streetcast	Urban	V2I	Distance	RSU
POCA	Both	V2V	Distance	Store carry forward
DECA	Both	V2V	Density information around node	Store carry forward
Ack-PBSM	Both	V2V	Connected dominating set	Store carry forward
