车联网中汽车位置管理策略研究

Research on Automobile Location Management Strategies in Vehicle Network

针对车联网拓扑结构,研究分析部署环境复杂度,将车联网拓扑划分为城镇二维拓扑结构和非城镇一维拓扑结构,针对两种拓扑结构特点,分别对其制定相应位置更新策略以减少更新开销,对城镇二维拓扑提出基于位置区的分层管理的位置更新策略,对非城镇一维拓扑提出相邻位置区重叠更新策略.本管理策略在适应车联网结构的同时减小了位置管理的开销.

According to the topology of the vehicle network, research and analysis of the complexity of the deployment environment, the vehicle network topology is divided into two dimensional topological structure of urban and non-urban one dimensional topological structure. Aiming at the characteristics of two kinds of topology structure, respectively, to formulate the corresponding location update strategy to reduce the cost of update, according to the two dimensional topological structure of urban is proposed for update strategy based on hierarchical location management, and put forward the update strategy of adjacent location areas overlap each other in non-urban one dimensional topology structure. The management strategies can meet vehicle network structure and reduce the location management cost.
