“…Its main idea is to construct a load balancing backbone route composed of Mesh routers to ensure the quality of service (QoS) under various network connectivity and load scenarios. In addition to these protocols committed to load balancing at the RSUs, load‐balanced GPSR and CLGF improved GPSR by taking into account the load status of the nodes when selecting the next hop. The protocol not only balanced the network traffic load but also decreased the latency.…”

SUMMARYThe characteristics of vehicular ad hoc networks (VANETs) make the design of routing protocol a great challenge. In this paper, we propose a vehicle density and load aware routing protocol for VANETs called VDLA. VDLA adopts sequential selection of junctions to construct the route. The selection is based on the real-time vehicle density, the traffic load, and the distance to the destination. The network information is collected by a decentralized mechanism. Through factoring in these metrics, the packets are avoided being sent to roads where network is disconnected, and the network load is balanced to mitigate network congestion. The intermediate junctions are selected before the packet reaches a junction to reduce the unnecessary hops. Our study also investigates the impact of the high mobility of the nodes. An analytical framework is proposed to analyze the mobility. Based on the analysis, the traditional Hello scheme is enhanced to improve the accuracy of the neighbor table. In the simulation, we compare VDLA with greedy perimeter coordinator routing and GpsrJ+, which are geographic routings protocols proposed for VANETs. The results validate the superiority of VDLA in terms of end-to-end delay and packet delivery rate. And the superiority holds in different scenarios.
