We propose a scheme to implement lossy data compression for discrete equiprobable sources using block codes based on sparse matrices. We prove asymptotic optimality of the codes for a Hamming distortion criterion. We also present a sub-optimal decoding algorithm, which has near optimal performance for moderate blocklengths.
Text Wireless sensor networks (WSNs) have emerged as an important application area resulting from the advancement of efficient short-range radio communication and miniaturization of computing devices. In a WSN, the nodes are deployed with limited battery energy and therefore enhancement of network lifetime by minimizing energy-usage is of utmost importance.(More)
