CGT Method of Message forwarding

In vehicular ad hoc networks (VANETs),
because of the nonexistence of end-to-end connections, it
is essential that nodes take advantage of connection
opportunities to forward messages to make end-to-end
messaging possible. Thus, it is crucial to make sure that
nodes have incentives to forward messages for others,
despite the fact that the routing protocols in VANETs are
different from traditional end-to-end routing protocols.
In this paper, stimulation of message forwarding in
VANETs is concerned. This approach is based on
coalitional game theory, particularly, an incentive scheme
for VANETs is proposed and with this scheme, following
the routing protocol is in the best interest of each node. In
addition, a lightweight approach is proposed for taking
the limited storage space of each node into consideration.
