The notion of a smart home with integrated sensors, actuators, wireless network and a graphical user interface is very enticing. This paper presents the design and implementation of reliable, flexible, secure and economical sensor network for transforming traditional home into a smart home. The heterogeneous sensor and actuator nodes based on wireless networking technologies are deployed in the home...
Some Networked Control Systems (NCSs) require both wired and wireless nodes such as moving parts in automated workcells. Such an NCS is investigated in this paper as a case study. It has 2 wireless sensors, 14 wired sensors, 2 wireless actuators, 2 wired actuators and a wired supervisor. The architecture is based on Sensor-To-Actuator (S2A) model. It is shown via OMNeT++ simulations that the system...
This paper studies a Wireless Networked Control System which utilizes the IEEE 802.11b protocol without modifications to communicate between sensors and actuators in a production line environment. OPNET simulations are used to measure the end-to-end delay from sensor to controller and then from controller to actuator. It is observed that the measured delays, including all types of data processing,...
