代码说明:

  Matlab中有很多根据多边形顶点计算多边形面积,对多边形涂色等函数,但是并没有对多边形顶点进行凸多边形排序问题,所以写了这个对可以构成凸多边形的顶点进行排序的算法。( 此子程序功能为逆时针排列多个可构成一个凸多边形的顶点 输入参数xv是这些顶点的横坐标集合 yv是这些坐标的纵坐标集合 返回的排列好的点的横坐标和纵坐标集合. 使用示例: [x y]=rangePolyponPoint([0 10 10 0],[0 10 0 10]) 输出结果为:x = [ 0 10 10 0], y = [ 0 0 10 10].)

  • Blocking-EDS
    Since RREQ packets are flooded throughout the network, this algorithm does not scale well to large networks. If the destination node is located relatively near the source, issuing a RREQ packet that potentially pass through every node in the network is wasteful. The optimization AODV uses is the expanding ring search algorithm, which works as follows. The source node searches successively larger areas until the destination node is found. This is done by, for every RREQ retransmission until a route is found, incrementing the time to live (TTL) value carried in every RREQ packet, thus expanding the ``search ring in which the source is centered.
