The main objective of the REMPLI project is to develop a distributed infrastructure suitable for real-time monitoring and control of energy distribution and consumption. PLC technology has been chosen to form the main communication infrastructure. The targeted applications possess different requirements in terms of Quality-of-Service (QoS) that should be taken into account by the underlying network. This comes to say that a traffic dispatching policy must be defined which guarantees minimum bandwidth utilization through periodic traffic and short end to end delay of aperiodic data request services.
