An energy saving audio compression scheme for wireless multimedia sensor networks using spatio-temporal partial discrete wavelet transform ?
Energy saving data compression for WMSNs with randomly deployed nodes. Energy is primarily saved by exploiting spatial and temporal correlation together. It is further saved by proposing a tree based routing which ensures unidirectional data flow toward the sink. A lossless encoding scheme is proposed to save energy further.
