| 摘 要： | 提出了建立在Ad hoc网络分簇结构上的多级移动数据库模型.该模型在Ad hoc网络分簇的基础上建立了多级数据服务系统,形成了由主服务器、多级本地服务器和移动主机组成的多级结构.仿真实验证明:该模型相对传统移动数据库模型有更高的效率和可靠性,有效减少因为路由造成的巨大通信流量,减轻网络负载,而且随着网络节点数量的增加,该模型的优势更加明显.

| Abstract: | A multilevel mobile database model based on clustering in Ad hoc network( CMMDB) was presented. In this mode a multilevel mobile data services system was established which was composed of main database server, multilevel local database servers and mobile computers. The results of simulation experiments showed that the CMMDB model gained higher efficiency and reliability than traditional mobile database mode. It could effectively reduce the communication flows caused by routing and lighten the network load. Moreover the superiority of the CMMDB mode became more outstanding with the increase of the number of nodes. |
