A Novel Routing Protocol for VANETs Based on Link Stability and Available Bandwidth
Ako Muhammad Abdullah
Vehicular Ad hoc Networks (VANETs) are a subclass of MANETs that focuses on a variety of applications, including intelligent traffic management and safety. Traditional ad hoc routing protocols such as ad hoc on-demand distance vector (AODV) are challenging and cannot work efficiently in VANETs due to rapid topology changes and frequent disconnection. In this paper, a simple approach is proposed to improve the performance of the AODV routing protocol in VANETs by selecting the most reliable and stable links to establish the route between the source and destination nodes (vehicles). In this approach, the link expiration period, available link bandwidth, and hop counts are used as significant metrics to construct an optimal route from source to destination. In addition, to avoid frequent route breakage and reduce the packet loss ratio, a Dynamic route resetting mechanism is proposed. The simulation results show that the proposed routing scheme can efficiently work in VANETs.
