Time Division Antenna Switching Using 3 ,4 and 6 Antennas at the trasimitter side and 1 antenna at reciever side using Channel Coding

In mathematics, the method of steepest descent or stationary phase method or saddle-point method is an extension of Laplace s method for approximating an integral, where one deforms a contour integral in the complex plane to pass near a stationary point (saddle point), in roughly the direction of steepest descent or stationary phase.

WSNs的LEACH路由算法，它是一种层次型算法，核心思想是分簇，并轮流当选簇头！(WSNs LEACH routing algorithm, which is a hierarchical algorithm, the core idea is clustering, and turns elected cluster head!)
