Abstract-- In this paper, we propose an "in-network" diversity
combining scheme for image transport in wireless sensor net-
works. We consider a wireless sensor network with both wireless
link impairments and node failures. We investigate two perfor-
mance metrics of the proposed image transport scheme: energy
consumption and received image quality distortion. Simulation
results show that the proposed image transport scheme improves
the robustness to network errors at the expense of low energy
overhead. This improvement is more noticeable in case of high
node failure probability and long distance between the source
and the destination. Our work also helps in understanding the
tradeoffs between image quality distortion and energy consump-
tion with different network parameters such as the number of
hops between the source and the destination, the average channel
