    Article: Developing a new wireless sensor network platform and its application in precision agriculture.
    [show abstract] [hide abstract]
    ABSTRACT: Wireless sensor networks are gaining greater attention from the research community and industrial professionals because these small pieces of "smart dust" offer great advantages due to their small size, low power consumption, easy integration and support for "green" applications. Green applications are considered a hot topic in intelligent environments, ubiquitous and pervasive computing. This work evaluates a new wireless sensor network platform and its application in precision agriculture, including its embedded operating system and its routing algorithm. To validate the technological platform and the embedded operating system, two different routing strategies were compared: hierarchical and flat. Both of these routing algorithms were tested in a small-scale network applied to a watermelon field. However, we strongly believe that this technological platform can be also applied to precision agriculture because it incorporates a modified version of LORA-CBF, a wireless location-based routing algorithm that uses cluster-based flooding. Cluster-based flooding addresses the scalability concerns of wireless sensor networks, while the modified LORA-CBF routing algorithm includes a metric to monitor residual battery energy. Furthermore, results show that the modified version of LORA-CBF functions well with both the flat and hierarchical algorithms, although it functions better with the flat algorithm in a small-scale agricultural network.

    Chapter: Overview of Networked Control Systems
    [show abstract] [hide abstract]
    ABSTRACT: Networked control systems (NCS) have been one of the main research focuses in academia as well as in industrial applications for many decades. NCS has taken the form of a multidisciplinary area. In this chapter, we introduce NCS and the different forms of NCS. The history of NCS, different advantages of having such systems are the starting points of the chapter. Furthermore, the chapter gives an insight to different challenges which come with building efficient, stable and secure NCS. The chapter talks about different fields and research arenas, which are part of NCS and which work together to deal with different NCS issues. A brief literature survey concerning each topic is also included in the chapter. iSpace is the test-bed for NCS and it attends the practical issues and implementation of NCS. At the end, iSpace at ADAC is presnted as a case study for NCS with different experimental results.
