摘要
通过把Adhoc网络区域划分为虚拟网格,使主机掌握网络区域的地形情况。在网络区域地形已知的条件下给出了一种改进的基于地理位置的分组转发路由算法;同时利用hash函数给出了一种新的位置管理方案。所给的位置管理方案具有完全可扩展性,而且不依赖于对网络区域的分级划分。
The geographic area of the Ad hoc network is partitioned into virtual grid.By the partition,each host can learn the information of the landform of the area.A modifying routing algorithm of the geographical forwarding is presented by exploiting the information of the landform.At the same time ,by using hash function,this paper give s a completely scalable location management scheme which is no dependence on the hierarchy partition of the network area.
