Vehicle Assignment as RSU For Improving Roads Safety, Coverage Extension Approach

Road side units are acting towers that responsible to relay the traffic among the mobile nodes. Normally, RSUs are limited according to network planning constrains. Hence, a new approach is proposed to employ the moving cars to act as RSU towers. We proposed using the mobile node to act as Road Side Unit (RSU) and perform data packet routing as Road Side Unit (RSU) does. The main problem of using large number of Road Side Unit (RSU)s is performance degradation be consumption of large time for data delivery. In this paper, we attempted using different number of mobile nodes as Road Side Unit (RSU)s which is differs from classical Road Side Unit (RSU)s as the last is static and other is dynamic (in motion). Outcomes of this study shown that large number of mobile nodes as Road Side Unit (RSU)s may enhance the connectivity by reducing the link re-healing time and maintaining the connection for longer time.
