  • LCN - Indoor Location for Smart Environments with Wireless Sensor and Actuator Networks
    2017 IEEE 42nd Conference on Local Computer Networks (LCN), 2017
    Co-Authors: Zhongliang Zhao, Stephane Kuendig, Blaise Carron, Torsten Braun, Jose Luis Carrera, Jose Rolim
    Abstract:

    Smart environments interconnect indoor building environments, indoor wireless sensor and Actuator Networks, smartphones, and human together to provide smart infrastructure management and intelligent user experiences. To enable the "smart" operations, a complete set of hardware and software components are required. In this work, we present Smart Syndesi, a system for creating indoor location-aware smart building environments using wireless sensor and Actuator Networks (WSANs). Smart Syndesi includes an indoor tracking system and a WSAN for environmental monitoring and Actuator activation, interconnected via a gateway with mobile users. The indoor positioning system tracks the real-time location of occupants with high accuracy, which works as a basis for indoor location-based sensor actuation automation. To show how the multiple software/hardware components can be integrated, we implemented a system prototype and performed intensive experiments in indoor office environments.

  • Autonomic Wireless Sensor/Actuator Networks for Tracking Environment Control Behaviors
    2020
    Co-Authors: Masayuki Nakamura, Atsushi Sakurai, Jiro Nakamura, Morinosato Wakamiya
    Abstract:

    To develop energy-saving environment control systems, we propose autonomic wireless sensor/Actuator Networks that classify a user’s behaviors in relation to environment control such as lighting, and that configure themselves depending on sensor node selection. In our system, a wireless remote control node monitors a user’s actions with respect to environment control, and occupancy sensor Networks simultaneously detect the user’s movement. The system learns the relationship between the responses of the remote control node and the occupancy sensor Networks to classify the user’s behaviors with only the occupancy sensor Networks. The system chooses informative sensor nodes for this behavior classification based on an information gain criterion. These chosen nodes have a high sensing cost. Sensor network routing is controlled based on the sensing cost and communication cost metric. In the resultant sensor Networks, the sensing performance is the same as that in the original network, but the resources are successfully allocated to the nodes. In addition, less informative and redundant nodes are identified. We demonstrate tracking environment control behaviors and sensor node selection using the sensor/Actuator Networks testbed.

  • distributed environment control using wireless sensor Actuator Networks for lighting applications
    Sensors, 2009
    Co-Authors: Masayuki Nakamura, Atsushi Sakurai, Jiro Nakamura
    Abstract:

    We propose a decentralized algorithm to calculate the control signals for lights in wireless sensor/Actuator Networks. This algorithm uses an appropriate step size in the iterative process used for quickly computing the control signals. We demonstrate the accuracy and efficiency of this approach compared with the penalty method by using Mote-based mesh sensor Networks. The estimation error of the new approach is one-eighth as large as that of the penalty method with one-fifth of its computation time. In addition, we describe our sensor/Actuator node for distributed lighting control based on the decentralized algorithm and demonstrate its practical efficacy.

    Proceedings of the 5th international conference on Soft computing as transdisciplinary science and technology - CSTST '08, 2008
    Co-Authors: Masayuki Nakamura, Atsushi Sakurai, Takumi Yamada, Jiro Nakamura
    Abstract:

    To develop an energy-saving environment control system, we propose wireless sensor/Actuator Networks which classify the user's behaviors for environment control such as lighting and configure the network according to sensor node selection. In our system, a wireless remote control node monitors the user's environment control actions and occupancy sensor Networks detect the user's movement simultaneously. The system learns the relationship among the responses of the remote control node and the occupancy sensor Networks to classify the user's behaviors only with the occupancy sensor Networks. The system chooses informative sensor nodes for the behavior classification based on the information gain criterion. These chosen nodes have high sensing cost. Sensor network routing is controlled based on the sensing cost and communication cost metric.

  • Improved Collaborative Environment Control Using Mote-based Sensor/Actuator Networks
    Proceedings. 2006 31st IEEE Conference on Local Computer Networks, 2006
    Co-Authors: Masayuki Nakamura, Atsushi Sakurai, Toshio Watanabe, Jiro Nakamura
    Abstract:

    We propose an improved decentralized method for environment control in wireless sensor/Actuator Networks. In our method, the objective function is defined to balance energy saving against control signal quality. Each sensor node calculates initial values in an iterative process for estimating optimal control signals using the sensor signals received from neighboring nodes. We evaluated its accuracy and efficiency by using motes

  • MASS - TARP: A Trust-Aware Routing Protocol for Sensor-Actuator Networks
    2007 IEEE Internatonal Conference on Mobile Adhoc and Sensor Systems, 2007
    Co-Authors: Abdelmounaam Rezgui, Mohamed Eltoweissy
    Abstract:

    Most routing protocols for sensor-Actuator Networks (SANETs) are built under the assumption that nodes normally cooperate in forwarding each other's messages. In practice, this assumption is not realistic; SANETs are environments where nodes may or may not cooperate. For several reasons, a node may fail to operate as planned at deployment time. As a result, when actually deployed, protocols and applications may not be as efficient as expected. In this paper, we present TARP (Trust-Aware Routing Protocol), a routing protocol for sensor-Actuator Networks that exploits past nodes' routing behavior and links' quality to determine efficient paths. We implemented TARP in a TinyOS-based SANET and conducted several experiments to evaluate its performance. The obtained results confirmed that TARP achieves substantial improvements in terms of energy consumption and scalability.

  • A service-oriented query architecture for sensor-Actuator Networks
    2006 2nd IEEE Workshop on Wireless Mesh Networks, 2006
    Co-Authors: Abdelmounaam Rezgui, Mohamed Eltoweissy
    Abstract:

    Current architecture and programming paradigms are not able to support the requirements of emerging sensor- Actuator applications. In this paper, we discuss those requirements and propose service-oriented sensor-Actuator Networks (SANETs) as a novel programming and querying paradigm that is able to cope with the requirements of future sensor-Actuator systems.
