Abstract-Efficient compression and transmission of images in a resource constrained multihop wireless network is considered. Distributed image compression is proposed as a means to overcome the computation and/or power limitation of individual nodes by sharing the processing of tasks. It has the additional benefit of extending the overall lifetime of the network by distributing the computation load among otherwise idle processors. Two design alternatives for energy efficient distributed image compression are proposed and investigated with respect to energy consumption and image quality. Simulation results show that the proposed scheme prolongs the system lifetime at a normalized total energy consumption comparable to centralized image compression.
The work in REF proposed a distributed image compression algorithm based on JPEG2000 as a means to overcome the computation and/or energy limitation of individual nodes by sharing the processing of tasks.
