Abstract—SCADA systems are widely used by numerous industries

in order to control a variety of processes. During

the development of such a system, one is faced with several

challenges concerning reliability, security and congestion control.

For example, in a traffic light application, systems to handle

reliability and congestion control have to be carefully designed, in

order to meet the high safety requirements. In other applications,

especially wireless, security is of great importance.

This report is aimed to describe and address a few of these

challenges, but does so in a scaled down version. This project is

part of a larger activity with the overall purpose to navigate a

ground vehicle from a control station and provide an operator

with visual information. The work covered in this project will

focus mainly on implementing reliable data transfer over a

ZigBee radio link and on creating an adaptive protocol for

efficient transmission of images.

To make the existing software more robust to link congestions

and faults, we develop methods to handle lost data packets and

packet duplication. Additionally, we implement the capability of

image transmission from the vehicle to the control station that

makes use of an adaptive quality selector especially designed to

not interfere with the ability to control the vehicle.
