A sensor is equivalent to the human sense of sight and hearing. Various types of sensors are used in sewerage facilities to measure water flow, water pressure, water level and water quality. These sensors are expected to be improved upon in the future, with advanced precision and easier maintenance. On the other hand, new principles of instrumentation have been put to practical use, and the dev...

Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...

This paper describes a client–server architecture for the remote control of instrumentation over the Internet network. The proposed solution allows multiuser, multi-instrument sessions by means of a queueing and instrument locking capability. Client applications can be easily developed by using conventional high-level programming languages or well-assessed virtual instrumentation frameworks. Pe...

In this paper, we propose a model-based design approach for developing wireless sensor-actuator networks that can map multiple sets of application-level interactions onto a single networking substrate while still enforcing individual requirements. We use a top-down design approach where the functional requirements for each application are graphically modeled using a tool called SysWeaver. Senso...

In this paper we describe the problem of developing sensor fault detection within SHM instrumentation systems, and solutions based upon machine-learning techniques. We conclude with a report on our proof-of-concept demonstrator, and outline next-steps towards implementation of a autonomous selfdiagnostic sensor solution.

He received his Masters Degree from RWTH Aachen in 2007. His studies were funded by " DAAD-Siemens scholarship Asia 21 st century ". Hamad started his PhD in the March of 2008 under the PhD scholarship program of DAAD. His research interests include wireless sensor networks mainly focusing on modeling & simulation, protocol design, and link level optimizations. He is the lead developer of TimeT...
