In WSNs, wirelessly interconnected devices enable multimedia content such as video and audio streams to be ubiquitously retrieved, and still images along with scalar data from surroundings for a wide range of applications are constrained by the processing, memory, and power resources. Image compression through low-complexity and resource-efficient transforms has been addressed by several researchers to prolong the network lifetime where power conservation is achieved through sharing… Expand
