Predicting the Route of the Longest Lifetime and the Data Packet Delivery Time between Two Vehicles in VANET

Table 1

Comparison of existing schemes.

Scheme	Link lifetime: accurate or not accurate	The selected route has the longest lifetime: yes/no	Data packet delivery time		Participating vehicles
			Considered or not considered	Modeled or not modeled
MOPR [13]	Not calculated	No	Considered and not accurate	Not modeled	All vehicles
ROMSGP [8]	Not accurate	No	Considered and not accurate	Not modeled	Just vehicles that travel in the same group
PBR [14]	Not accurate	No	Not considered	Not modeled	Giving priority to vehicles that travel in the same direction
SDR [15]	Not accurate	No	Not considered	Not modeled	Only vehicles that travel in the same direction
EG-RAODV [10]	Not accurate	No	Not considered	Not modeled	All vehicles
ARP-QD [17]	Not accurate	No	Not considered	Not modeled	All vehicles
En-AODV [18]	Not accurate	No	Not considered	Not modeled	Only vehicles moving towards the destination region
CRLLR [12]	Not accurate	No	Not considered	Not modeled	All vehicles
AODV-R [19]	Not accurate	No	Not considered	Not modeled	All vehicles
MA-DP-AODV-AHM [20]	Not calculated	No	Not considered	Not modeled	Vehicles that their speed is lower than a threshold and they are not diverging
Our schemes	Accurate	Yes	Considered	Modeled	All vehicles
