一种引入阈值的Ad Hoc网络分级转发指针的位置管理策略

在移动Ad Hoc网络中,由于网络具有自组织性和节点的频繁移动,也就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,这就直接影响到网络的可扩展性。目前,在移动Ad Hoc网络中越来越多的引入了位置管理的策略,以达到减少网络开销的目的。引入分级转发指针和阈值的思想,提出了一种新的位置管理策略。通过与其他策略的方针比较,证明其在性能上具有更好的可扩展性。

Location management scheme of hierarchical forwarding pointer with thresholds for mobile Ad Hoc networks

In mobile wireless Ad Hoc networks,topology structure of network is changed very frequently because of the self-organization of networks and movement of nodes. Along with the number of nodes increasing, overhead of network rises rapidly,and it influences the extendible of network. Recently, in mobile wireless Ad Hoc networks location management is brought to reduce overhead of network. A novel strategy through hierarchical forwarding pointers and threshold idea is presented. By analysis, this scheme is a completely scalable location management scheme,which works well for large-scale mobile Ad Hoc networks.
