摘要
介绍了Ad Hoc网络路由协议(Ad Hoc On-Demand Distance Vector Routing,AODV)的路由机制和特点,提出了一种基于AODV的改进协议V-AODV。V-AODV改进了AODV的路由测度,用量化的节点移动性代替跳数作为路由代价的度量,在动态网络中能够选取到更加稳定的路由。仿真表明,V-AODV比AODV在时延和重传次数等性能上都有一定程度的提升。
The routing mechanism and characteristics of Ad Hoe network routing protocol Ad Hoc On-Demand Distance Vector Routing（AODV） is described first in this paper, Then a modified protocol V-AODV is proposed. V-AODV improves the routing measurement of AODV. It uses quantification of mobility instead of hops as the measure of routing cost, and thus the route is more stable than AODV in dynamic network. Simulation shows that V-AODV is better than AODV in delay, retransmission attempts, etc.
