In vehicle ad hoc networks (VANET), the network connectivity is frequently changed due to the high mobility of each communication node. Its mobility can be utilized for improving the message delivery ratio because vehicles as such nodes go along roads and their trajectory can be predicted. In this research, I have conducted the following tasks and have achieved a result: modeling a VANET and an analysis of its message delivery ratio considering the behavior of such high mobility nodes; developing a cooperative GPS/GNSS positioning with neighboring vehicles; developing a message delivery protocol where the network connectivity is frequently changed due to nodes with an unstable power supply model; modeling and analyzing motorcycles as a communication node in VANET.
