Description: A*算法是一个求最短路径的函数，为许多即时战略游戏所用刀（或许人家大型的即时战略游戏笔者算法更好，不管它）。它由两个函数组成，一个是评估函数，也就是确定人物移动的下一个位置必须离目标位置最近，评估函数评估的结果越精确，则寻径的速度越快；另一个就是寻径函数，也就根据评估的结果做出响应，然后从新位置继续评估下一个位置，若无路可走（四周都是障碍什么的），那么折回一个路径节点，尝试其他方向，这个算法有个缺点，随着游戏中人物增多，相应的处理节点就增多了，会影响处理速度，而且占用大量的内存。
有兴趣的朋友可以改成动态的寻径，就是当入口和出口位置都在变化的时候进行寻径，这个代码也只有200多行。
我的算法还不能算是最优的，因为评估函数只不过是简单的测试两点距离（这会带来误差），选择离出口最短的且非障碍物的方向，进行下一个路径节点的移动。-A * algorithm is a shortest path function, To many time strategy games as a knife (and perhaps others of immediate large-scale strategy game better writer algorithm, regardless of it).

Description: 用NS- 2 仿真各种路由协议性能时用到的传统运动场景发生器存在两个缺陷: 运动状态不能迅速过渡到稳态, 节点速度的

大缩短仿真时间, 在此基础上仿真AODV 和DSDV 两种路由协议, 首次从吞吐量、协议包开销、平均延迟三个方面对稳态运动场景
下的两种路由协议性能进行分析, 得出结论表明采用稳态运动场景进行路由协议仿真是非常必要的。
关键词: 稳态运动场景 setdest 更新过程 Random Waypoint-Abstr act: As a module of NS2, the traditional movement scenario generator, when simulating routing protocol, has two limitations.
One is that the transition time of stable status is long, and the other is that the uniform- distributing low bound of node speed is
only zero.To remedy these faults, Tracy Camp has developed a stable movement scenario generator.The simulation proves that
simulation time can be reduced largely by using this generator.Based on this result, a simulation for AODV and DSDV routing
protocol is implemented.Then the performance of two protocols is analyzed on three aspects: throughput, routing overhead packets,
average delay.At last the conclusion is drawn, which shows it is essential to adopt stable movement for simulation of routing
protocols.
