Decrease Number of Bit ID in Wireless Sensor Network by Using Huffman Algorithm

A wireless sensor network consists of many low-cost, low-power sensor nodes, which can perform sensing, simple computation, and transmission of sensed information. Long distance transmission by sensor nodes is not energy efficient, since energy consumption is a superliner function of the transmission distance., which can have their batteries And its sensing tasks in a given environment are doing. It is comprised of one or more master nodes which have sensed data is collected And a central processing and storage system communicates . A sensor node typically gets its power from a battery. Because a sensor network routing protocols require a node identifier These identifiers are required in securing these networks require a unique identifier on each packet has a header . The length of the ID is important in these networks . In this paper we solve the problem of assigning a unique identifier Huffman offer . We use a unique identifier Huffman codes , short for wireless sensor nodes . Our nodes are organized in a tree structure .This tree structure is used to calculate the size of the network and then form the Huffman tree to assign a unique ID to each node deals with the shortest name . Our algorithm for an area with a large number of sensors are simulated using Matlab software. We then evaluate the performance And the results more casts with the same density and non- uniform density compared to more casts. This work provides a solution to identify malicious nodes in wireless sensor networks through detection of malicious message transmissions in a network. A message transmissions considered suspicious if its signal strength is incompatible with its originator’s geographical position. We provide protocols for detecting suspicious transmissions – and the consequent identification of malicious nodes – and for disseminating this information in the network. We evaluate the detection rate and the efficiency of our solution along a number of parameters. The department has been using a new method for assigning Huffman node ID - the ID of the sensor introduced that will be the least bit.
