自己编写的利用matlab实现无线自组织网AODV仿真的算法源码。 为由50个节点构成的网络。在50m×50m大小的区域内，随机的产生50个节点。由用户指定源节点和目的节点，程序负责给出从源节点到目的节点的最小路径和此路径的跳数。各个节点之间设定为只要在自己直接通信范围内的其它节点，均一跳可达。(Write your own realization of the use of matlab simulation of wireless self-organizing network algorithms AODV source. The grounds of a network of 50 nodes. Size of 50m × 50m in area, randomly generated 50 nodes. By the user to specify the source node and destination node, the program responsible for the given node from the source node to the destination path and this path is the minimum number of hops. Set between each node to communicate directly as long as within the scope of their other nodes, all jump up.)

说明：  梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)
