QoS-aware routing for real-time and reliable wireless sensor network based Smart Grid NAN communications
Résumé
The deployment of Information and Communication Technologies (ICTs) within the conventional power grid has enabled new Smart Grid (SG) features and services. In this work, we focus on data routing within the distribution segment of the SG. We study communication requirements within this part of the power grid and we propose a classification of the data traffic based on Neighbourhood Area Network (NAN) communication requirements in terms of delays and reliability. Then, we introduce QoSGRACO, a routing protocol which takes account of the Quality of Service (QoS) of NAN’s traffic by using coloured
pheromones ant colonies. We show, through simulations, that QoS-GRACO is able to satisfy NAN’s requirements, especially in terms of delay and reliability.
