Lightweight Data Compression in Wireless Sensor Networks Using Huffman Coding
International Journal of Distributed Sensor Networks, 2014 This paper presents a lightweight data compression method for wireless sensor networks monitoring environmental parameters with low resolution sensors. Instead of attempting to devise novel ad hoc algorithms, we show that, given general knowledge of the ...
