In this paper, we discuss the theory, technology and algorithms of three-dimensional (3D) GIS visualization; it includes terrain surface modeling techniques of digital elevation model (DEM), basic theory of three-dimensional (3D) terrain visualization, Triangular Irregular Network (TIN) type and algorithms, dynamic three-dimensional terrain display techniques based on simplified model, and spatial searching techniques based on three-dimensional terrain map. OpenGL graphic function library is The most widely used industry standards in the world, we analysis its interface and function, design and construct the module based on that. In the end, we demonstrate the theory with a system that can display the 3d terrain we need.

adhoc网络中节点既是终端又是路由器的特性，决定了路由协议的优劣在很大程度上影响着adhoc网络的性能。AODV路由协议是目前adhoc网络的主流路由协议之一。在LINUX平台上，AODV的实现分为内核态和用户态两部分。路由算法模块在用户空间完成。本文旨在分析实现AODV的三个主要模块：内核模块，路由算法模块，服务模块及其相互之间的调用关系。并总结了AODV协议实现中LINUX内核的基本操作流程。
