Data Compression Techniques In Wireless Sensor Networks : A Survey

Energy efficiency is a primary concern since sensor nodes have to report regularly the sensing data to the remote sink(s) for a very long time. So data transmission is one of the major factors for the energy efficiency in sensor networks. More research work is focused on minimizing the data using data compressing techniques. Data compression is used to decrease the number of bits required to transmit the data of particular information. It is useful because it helps people to minimize the use of resources such as data storage capacity. The goal of data compression is to eliminate redundancy in the data in order to reduce its size. This paper surveys different data compression techniques in WSN.
