In all smart phones there are various applications (apps) which can be used for communication with each other. But many of these apps are sending text data in plain text format through network. When using such apps in a public Wi-Fi network, anybody can able to sniff incoming and outgoing messages. Data compression is a common requirement for most of the computerized applications. There are number of data compression algorithms, which are dedicated to compress different data formats. Even for a single data type there are number of different compression algorithms, which use different approaches. Mobile communication devices have become popular tools for gathering and disseminating information and data. This paper proposes an efficient data compression technique by doing some modification to Huffman Coding. The aim of this paper is to compress data to send through Android based mobiles to optimize bandwidth. Keywords: Huffman Coding, Mobile application, Data Compression. 1. Introduction Last decade has witnessed exponential rise in use of smart phone and communication applications of it. Actual reason behind it is the need of accessing online services and information and for staying connected to the world around them. As Carrying smart phone is easy than to carry the laptops and modem together. The users those are communicating online are also increased as the cost of data planes are in budget than the normal recharge options. The sudden rise in such users have created great opportunity in designing such applications which assures proper use of bandwidth and security issue. Compression implies reducing the quantity of data used to represent a file, image or video content without excessively reducing the quality of the original data. It also reduces the number of bits required to store and/or transmit digital media. To compress something means that you have a piece of data and you decrease its size. Huffman coding is a type of lossless data compression technique. Huffman coding is based on the frequency of occurrence of a data item i.e. frequency of occurrence of characters in text message. The technique is to use a lower number of bits to encode the data in to binary codes that occurs more frequently.
