In the proposed codec a ROI must be transmitted through the
network while adding additional information (e.g., x and y coordinates,
width and height dimensions). Nonetheless because of the
tiny size of the payload in 6LoWPAN data packets (equal to 96 bytes),
a single ROI (or background image) is fragmented into many
6LoWPAN packets. Following the arguments introduced above,
any error occurring in the application header (encoded in the first
packet) will critically disrupt the image reconstruction or the background
image update at the receiver side.
