Multi-factor Relay-Node Selection Algorithm for IoV in 3D Mountain Scenarios
摘要
In Internet of Vehicles, a multi-factor weighted relay-node selection method is proposed to address the problem that single-hop relay node performance is optimal but its multi-hop is not optimal, which exists on the greedy algorithm in 3D mountain scenarios. The ration for the algorithm is demonstrated by conducting a comprehensive analysis of the impact of 3D mountain features on the relay-node selection method. The experimental results in simulations on real-world map show that the designed algorithm performs better compared with the improved greedy algorithm.
