The document discusses how street lighting networks can become the driving force behind developing smart city networks. It describes how street lighting can be made intelligent through distributed control of individual luminaires using wireless communication. This allows dynamic lighting that responds to variables like traffic, ambient light levels, and events. The network could then provide additional smart city services on top of energy-efficient lighting by integrating other sensors and controls. An example project in Wavre, Belgium is presented that has implemented an intelligent lighting network with energy savings and remote monitoring capabilities, demonstrating how smart street lighting can be an early realization of smart city concepts.

 Local decision
Advantages
 No weak points in the
network
 Everything is local:
 Eventual system faults
 Network modifications and
adaptations
 Specificities : parameters,
traffic,...
 Installation ease
 Network growth
