Huffman coding

In the proposed Huffman LEACH model, energy consumption increases exponentially with distance and there are no maximum limits. The transmit power level of a sensor node can only be adjusted to discrete values that may result in one for various distances. resulting two links different distances equivalent. number clusters generated does not converge fixed value which shortens lifespan network. wireless network is inversely proportional lifetime Here, we assume defined as time from deployment WSN till first gateway dies. Hence, maximized by using parameter discussed this paper. If minimize CH nodes, then nodes minimized if their relative corresponding CH’s. experimental model says better its faster than lower data transmission rate when compared existing models.
