车用自组网中,有效的分层协议可以增强网络逻辑拓扑结构的稳定性,减小通信中继花费.提出利用相邻车辆节点之间的稳定和非稳定邻居关系,构建网络分层结构,同时利用优化策略选择网络中的最优簇头集合,在保证网络具有良好负载均衡度的基础上,提高网络层次结构的稳定性.仿真数据表明,算法在分层结构的稳定性以及负载均衡度等方面均优于其他算法.
In the automotive ad hoc network, an effective hierarchical protocol can enhance the stability of the network logical topology and reduce the cost of communication relaying. It is proposed to utilize the stable and unstable neighbor relationships between adjacent vehicle nodes to construct a network hierarchy , And use the optimization strategy to select the optimal cluster heads in the network to improve the stability of the network hierarchy on the basis of ensuring the good load balance of the network.The simulation results show that the stability of the hierarchical structure and the load balancing Degree and so on are better than other algorithms.
