Table 3: Pros and cons of the different dissemination schemes.

Scheme Pros Cons

Counter Easy implementation
High % of informed vehicles
Originally proposed for MANETs
High number of messages used

Distance Easy implementation
Low number of messages
Low performance in urban environments

eSBR Good performance in different environments
Improving distance results in terms of % of informed vehicles
GPS required

eMDR Improving eSBR
Reducing the number of messages used
High precision GPS required
Specially designed for urban environments

NJL High efficiency in urban scenarios
Reduced number of messages used
Aggressive broadcast storm reduction
High precision GPS required
Useless in highway scenarios

RTAD Adaptive dissemination scheme
High efficiency in different scenarios
Complex implementation
GPS required

FDPD Recommended for highway scenarios
Direction of vehicles is considered
GPS required
Low performance in urban scenarios
