根据切比雪夫近似得到的计算简正波的程序，能够较精确获得本地简正波(A Matlab code for computing normal modes based on Chebyshev approximations )

在1x1的单位矩形中随机部署传感器节点，而且假设每个节点的通信半径一样，要求利用蒙特卡洛算法进行1000次试验分别模拟出连通率随节点数增加以及通信半径增加的变化趋势。(Random units deployed in 1x1 rectangular sensor nodes, and assumed that the communication radius of each node, requires the use of Monte Carlo algorithm to simulate the 1000 trials were increased with the number of nodes increased connectivity and communication radius increasing trends.)
