In-network Data Compression in Wireless Sensor Networks Using Distributed Block Truncation Coding

Abstract

In-network data compression is achieved in a wireless sensor network using Block Truncation Coding technique. This provides data compression and the consequent energy saving. In Block Truncation Coding, binarization and fixing of quantization levels are the two major steps. By shifting the binarization pre-processing to the sensor nodes, in-network compression is realized.
