WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization. The problem addressed has been tackled for 1-D linear array and further extended to 2-Dimensions as stated in the next slides.

函数插值计算 分别输入已知节点的x,y值，待计算的节点的x值，以及显示结果的文本框。利用文本框和按钮上的事件触发一系列处理方法，包括把文本框里的字符串解析成double类型存放在数组中，以及利用lagrange插值公式计算出结果并填写在结果文本框中。

Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely balanced. -If the height of this binary tree is h, then leaves can be at level h or level h-1. -All leaves at level h are as far to the left as possible. -The data associated with all descendants of a node are smaller than the datum associated with this node. Implementation 1.using a linear array not a binary tree. -The sons of A(h) are A(2h) and A(2h+1). 2.time complexity: O(n log n)

Generate Possion Dis. step1:Generate a random number between [0,1] step2:Let u=F(x)=1-[(1/e)x] step3:Slove x=1/F(u) step4:Repeat Step1~Step3 by using different u,you can get x1,x2,x3,...,xn step5:If the first packet was generated at time [0], than the second packet will be generated at time [0+x1],The third packet will be generated at time [0+x1+x2], and so on …. Random-number generation 1.static method random from class Math -Returns doubles in the range 0.0 <= x < 1.0 2.class Random from package java.util -Can produce pseudorandom boolean, byte, float, double, int, long and Gaussian values -Is seeded with the current time of day to generate different sequences of numbers each time the program executes

DEV C++ 写的一个矩阵类，用列主元消去法求模的。类的构造函数接收矩阵的行列值或者是一个vector<vector<double> >类型的变量。没有用模板，数据类型是double.

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.
