Determining and Evaluating the Most Route Lifetime as the Most Stable Route Between Two Vehicles in VANET.
INNOVATIONS IN BIO-INSPIRED COMPUTING AND APPLICATIONS, IBICA 2017(2018)
摘要
One of the critical problems in VANET is the frequent breakdown of the path caused by the high mobility of vehicles. For this purpose, much searches has disclosed the route lifetime between source and destination vehicles as an important factor to improve the quality of service in the VANET network. Each solution propose his own technique to determine a stable route based on link lifetime and route lifetime; but they do not determine and select the most stable route between source and destination vehicles during the data packets transmission by selecting the longest route lifetime. For this reason, we propose two protocols that use vehicles' movement information to determine and evaluate the longest route lifetime as a most stable path for comfort applications in a highway environment. One uses the beacon message and the other does not use it. These new schemes increase the packets delivery ratio, the throughput and decrease the number of error messages generated during the transmission of data packets following of the vehicles density.
