Implementation of Modified Huffman Coding in Wireless Sensor Networks

Abstract: WSNs are composed of many autonomous devices using sensors that are capable of interacting, processing information, and communicating wirelessly with their neighbors. Though there are many constraints in design of WSNs, the main limitation is the energy consumption. For most applications, the WSN is inaccessible or it is unfeasible to replace the batteries of the sensor nodes makes the network power inefficient. Because of this, the lifetime of the network which has maximum operational time is also reduces. To… Show more

“…Sadler et al [15] proposed the sensor Lempel Ziv Welch (S-LZW) algorithm based on the LZW algorithm for sensor systems by balancing three parameters: the dictionary size, and the data size for compression and processes with a full dictionary. In [4], Malleswari et al introduced the implementation of modified Huffman coding for WSN, where the Huffman algorithm is employed for the compression and decompression of data in order to minimize the size of the data packet and save energy.…”

“…A. Distributed Source Coding DSC based on the Slepian-Wolf theorem is one of the most efficient techniques, to compress correlated data sources [4,16]. In DSC, the correlated signals from a few sensor nodes are compressed with a totality rate greater than or equal to the joint entropy thus they decrease data packet size.…”
