为了解决车辆自组织网络中信息传递质量较差的问题,提出了一种基于权重的本地通信质量保证分簇算法,将分簇后的车辆节点划分为自组织层和对等层两层,自组织层节点使用车间通信方式进行通信,对等层节点利用3G、LTE等更可靠的传统通信方式进行通信.该算法对经典的权重分簇算法进行改进,以本地最优化代替全局最优化,引入保障通信质量最大可接受通信距离的概念,并提出了新的簇结构维护策略.仿真实验结果表明,与经典的权重分簇算法相比,该算法具有更高的簇结构稳定性和更高的分组投递率以及更低的开销.
In order to solve the problem of poor quality of information transmission in a vehicle self-organizing network, a weight-based local communication quality assurance clustering algorithm is proposed. The clustered vehicle nodes are divided into two layers, self-organizing and peer-to-peer Tier nodes communicate using shop floor communication and peer nodes communicate using more reliable traditional communication methods such as 3G and LTE.This algorithm improves the classical weighted clustering algorithm and replaces the global optimization with local optimization The concept of guaranteeing the maximum acceptable communication distance of communication quality is proposed and a new strategy of cluster structure maintenance is proposed.The simulation results show that the proposed algorithm has higher cluster stability and higher robustness than the classical weighted clustering algorithm Packet delivery rate and lower overhead.
