一种高斯-马尔科夫模型下的车辆位置管理策略

Location management based on Gauss-Markov model for vehicular Ad Hoc network

在车载自组网VANET中,节点的高移动性使得网络的拓扑结构频繁变化。随着节点数目的增加,网络的开销迅速增大,直接影响到网络的可扩展性。为此,将位置管理的策略引入VANET网络中,以达到减少网络开销的目的。在高斯-马尔科夫移动模型的基础下,提出了一种新的位置管理策略,实现车辆在低开销下的可靠通信。通过仿真比较,验证其在性能上具有更好的可扩展性。

In Vehicular Ad Hoc Network（VANET）, topology structure of network is changed very frequently because of the high mobility of nodes. With the number of nodes increasing overhead of network rises rapidly, and it influences the extendible of network. So, in vehicular Ad Hoc networks location management is brought to reduce overhead of network. A new location management based on Gauss-Markov model is presented, and it can achieve low overhead in vehicle-to-vehicle communication. Through simulation and comparison, this scheme is a completely scalable location management scheme, which works well for large-scale vehicular Ad Hoc networks.
