description |
Many safety and non-safety related applications have been envisioned in VANETs. However,
efficient data dissemination considering the mobility of vehicle is must for the success of these
applications. Although the Road Side Unit (RSU) is a stationary unit, both RSU and vehicle have
limited transmission range that restricts to shorter connection time. This endures a higher request
drop rate specially at the overloaded RSUs. A cooperative load balancing (CLB) among the
RSUs to use their residual bandwidth can be an effective solution to reduce the request drop rate.
In this paper, we investigate that considering the remaining delay tolerance of submitted requests
and the knowledge of fixed road layout, the performance of the cooperative load balancing system
can be further improved significantly. We show that this performance gain comes from serving
the requests based on the urgency and the efficient load balancing among the junction-RSUs and
edge-RSUs. Based on the observations, we propose an Enhanced CLB (ECLB) approach in this
paper. To demonstrate the efficiency of the ECLB approach a number of well-known scheduling
algorithms are integrated and an extensive simulation experiments are conducted in the vehicular
communication environment that supports the superiority of ECLB over the existing approaches. |
