In image transmission application over WSN energy efficiency and image quality are both important factor for joint optimization. The large size image transmission cause bottleneck in WSN due to the limited energy resources and network capacity. Since some sensor are in similar viewing directions the images they are capture likely exhibit certain level of correlation among themselves. This optimization scheme allows each image sensor to transmit optimal functions of the overlapped images through appropriate multiple rate oriented routing paths.
