also be easily modified or upgraded by adding sensors, actuators, and controllers to them with relatively low cost and no major change in their structure. Furthermore, featuring efficient sharing of data between their controllers, NCSs are able to easily fuse global information to make intelligent decisions over large physical spaces.

Advent and development of the
Internet combined with the advantages provided by NCS attracted the interest of researchers around the globe. Along with the advantages, several challenges also emerged giving rise to many important research topics. New control strategies, kinematics of the actuators in

The most important feature of an NCS is that it connects cyberspace to physical space enabling the execution of several tasks from long distance. In addition, NCSs eliminate unnecessary wiring reducing the complexity and the overall cost in designing and implementing the control systems. They can
