The main characteristic of Wireless Multimedia Sensor Networks (WMSNs) is nodes with limited energy

memory and computational power. Motivated by this

the concept of in-network processing has been proposed which greatly inspires the study of compression and transmission of big size and high resolution images in WMSNs. Based on the characteristic of JPEG2000 and the network architecture of WSNs

the paper proposes a multi-node cooperative JPEG2000 image compression method based on neighbor clusters. Firstly

the images captured by the camera node are partitioned into tiles. Then the tiles are sent to the neighbor clusters and compressed by multiple nodes cooperatively. Simulation results show that the proposed image compression method not only makes the JPEG2000 compression of big size images a reality in the WSNs

but also greatly lightens the energy consumption burden on the camera node which leads to a longer network lifetime.
