摘要: 在移动Ad hoc网络中,由于网络的自组织性、节点的频繁移动以及节点数目的增加,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网络中越来越多地引入了位置管理的策略,以达到减少网络开销的目的。引入锚策略的思想,提出了一种新的位置管理策略。在这种锚策略下,离家乡区域较远节点的位置更新不需报告它的家乡区域,该节点只需把位置更新信息登记到附近的锚区域。通过与其他策略的仿真比较,证明其在性能上具有更好的可扩展性。

关键词: 移动Ad Hoc网络, 位置管理策略, 锚策略

Abstract: In mobile Ad Hoc networks,overhead of network rises rapidly because of the self-organization of networks,movement of nodes along with the number of nodes increasing.And it influences the extensibility of network.Recently,in mobile Ad Hoc networks location management is brought to reduce overhead of network.A novel strategy based on anchor is presented.In such a strategy,the node away from its home region does not need to update the location information to its home region.And it can update the location information to anchor in the vicinity of the region.By analysis,this scheme is a completely scalable location management scheme,which works well for large-scale mobile Ad-Hoc networks.

Key words: mobile Ad Hoc networks, location management scheme, anchor
