Efficient utilization of energy is a core area of research in wireless sensor networks. Data compression methods to reduce the number of bits to be transmitted by the communication module will significantly reduce the energy requirement and increase the lifetime of the sensor node. Through analysis the probability distribution of sensor data and a classic compression algorithm named ND-Encoding, this...
Efficient utilization of energy is a core area of research in wireless sensor networks. Data compression methods to reduce the number of bits to be transmitted by the communication module will significantly reduce the energy requirement and increase the lifetime of t a he sensor node. The discrete cosine transform can significantly reduce the spatio-temporal correlations among input data and...
Efficient utilization of energy is a core area of research in wireless sensor networks. Data compression methods to reduce the number of bits to be transmitted by the communication module will significantly reduce the energy requirement and increase the lifetime of the sensor node. This paper divides WSN applications into two categories, slowly-varying applications and non-slowly-varying applications,...
