Abstract-- Efficient compression and transmission of images
in a resource constrained multihop wireless network is consid-
ered. 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 pro-
cessors. 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.
