Research on the Stability of Multi-Hop Clustering Based on Neighbor Following Method in Vehicular Networks
In view of the problems of high demand of computation offloading in vehicular networks and the randomness of topology variation of vehicular networks
this paper proposes a vehicular multi-hop clustering scheme based on neighbor following and investigates its stability by multiple indicators. Existing research offers various vehicular clustering schemes
but they suffer from issues such as single indicator
being limited to a single hop or fixed number of hops
low clustering efficiency
and lacking a mechanism for cluster head replacement. As the neighbor following strategy has better stability and higher clustering efficiency
in the scheme designed in this paper
vehicles should follow the most stable vehicle based on the comprehensive indicators within neighboring nodes. The de-ringing and pruning algorithms are used to standardize and flatten the following structure of vehicles
forming a more stable vehicular cluster. The master-slave cluster header and the cluster maintenance mechanism are employed to enhance the robustness of vehicular cluster. Simulation results show that the proposed algorithm outperforms existing methods in terms of cluster stability and clustering efficiency.
