摘　　要：提出了一种用于大规模Adhoc(自组织网)网络的虚拟骨干网分布式路由协议(VBDAR),该协议首先分布式构建Adhoc虚拟骨干网,然后在骨干节点上运行传统的Adhoc路由协议.协议通过减少网络中参与路由计算的节点数显著降低了冗余路由信息的传播.仿真结果表明,该协议能减少Adhoc网络中的路由跳数,并能有效地提高网络业务的性能.A Virtual Backbone-based Distributed Ad hoc Routing (VBDAR) protocol, which is suitable for large scale Ad hoc networks, is proposed. This protocol will construct Ad hoc virtual backbone at first, and then running classic Ad hoc routing protocols on it. Redundancy messages can be significantly reduced as only virtual backbone nodes perform routing algorithm. The results of simulation show that it can reduce the number of hops of routes, and will effectively improve the performance of services.
