The present article deals with a fault and delay tolerant multi-sensor control scheme. In particular, we consider a process affected by additive disturbance which is monitored by redundant sensors. The process is controlled by a digital controller which is connected with the sensors via shared network. It is assumed that sensors are subject to abrupt faults while the communication between the s...

The security in wireless multimedia sensor network is a crucial challenge engendered by environmental, material constraint requirements and the energy consumption. Standard encryption algorithms do not agree with the real-time applications on this network. One of the solutions to the challenges mentioned above is to maintain the safety and reduce the energy consumption. In this article, a new a...

This paper proposes Spinning Sensors, a middleware system for creating robotic sensor network applications. This middleware enables application programmers to easily write application software which utilizes both sensors and actuators in their network. In the Spinning Sensors model, a sensor node is attached to a robotic actuator to change its position and/or direction. The continuous position ...

As a promising technology that enables ubiquitous computing and leads IT industries of next generation, sensor networks (SN) are foreseen to expand and populate the globe in such a way as the present Internet does. In this scenario, new challenges appear with such massive deployment, as the constant interaction of nodes and networks will transform them in dynamic entities that will need to evol...
