Modified Huffman Coding Technique for High Secured Data Transmission
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
In recent years, data encoding has become more popular in network access. Providing security for the data being transferred plays a crucial role. The rapid development in wired and wireless digital communication has made the extensive use of the text data. However, there are few researches focusing on encoding data, providing security and memory usage. The basic characteristics of text data like transmission rate, bandwidth, redundancy, bulk capacity and co-relation among text data makes basic compression algorithms mandatory. The incoming data is received using a wireless sensor .Therefore this paper considers the problem of area optimization and providing security to allow low bit rate transmission based on HUFFMAN coding. As for n bit being transmitted it requires 2n memory stack for further increase in the data bits it requires 2n+1 memory stack which is wide waste of memory if there presents redundancy bits. Image transmission has large repeated sequences at some places which can be considered as redundant. The proposed method uses stuffing bits in order to provide high security, speed, area optimizaton and also to avoid retention faults.
