【摘要】：针对车载自组织网络(VANET)中节点的移动引起的传输链路不稳定的问题,提出一种基于节点运动方向预测的AODV路由选择方法。利用马尔可夫链的预测性,结合节点的运动特征,提出一种可降低节点移动对链路稳定性影响的路由选择算法,即路径最小概率最大算法。在路由建立阶段,对节点的马尔可夫性质进行验证,判断节点的类型,根据节点类型选择路由建立的策略。仿真结果表明,所提方法能够有效减少传输链路的建立次数和路由中断率,提高传输链路的稳定性。
[Abstract]:In order to solve the problem of unstable transmission link caused by node movement in vehicle-mounted ad hoc networks, an AODV routing method based on the prediction of node motion direction is proposed. Based on the prediction of Markov chain and the motion characteristics of nodes, a route selection algorithm, which can reduce the influence of node movement on link stability, is proposed, that is, the maximum path minimum probability algorithm. In the phase of routing establishment, the Markov property of nodes is verified, the type of nodes is judged, and the strategy of routing is selected according to the type of nodes. Simulation results show that the proposed method can effectively reduce the number of establishment of the transmission link and the routing interruption rate, and improve the stability of the transmission link.
