  • IEEE ANTS - Topology control algorithm for IEEE 802.15.4 based single sink wireless sensor networks
    2011 Fifth IEEE International Conference on Advanced Telecommunication Systems and Networks (ANTS), 2011
    Co-Authors: Sunil Jardosh, Prabhat Ranjan
    Abstract:

    IEEE 802.15.4 is a communication standard specifically designed, targeting resource constrained networks. IEEE 802.15.4 provides MAC and Physical layer specifications for low power personal area networks like wireless sensor networks. IEEE 802.15.4 is designed considering the energy concerns of network devices normally called sensor nodes in wireless sensor networks. As per the standard network nodes are categorized as Full Function device (FFD) nodes or Reduced Function device (RFD). Here FFD spends more time in active state and consumes more energy while RFD spends more time in sleep state and consumes less energy compared to FFD. Objective of topology control mechanism is to reduce the number of active devices without compromising network functionality. We have proposed a distributed, multi-point relay based topology control algorithm to construct a Connected Dominating Set (CDS) for the randomly deployed network nodes. CDS restricts the number of active nodes that improves the overall networks energy utilization and extends the network life.

  • On-Building remote controlled system for several home appliances using ZIGBEE
    2017 IEEE International Conference on Smart Technologies and Management for Computing Communication Controls Energy and Materials (ICSTM), 2017
    Co-Authors: Trisha Ghosh, Sneha Tiwari, J. Sahay
    Abstract:

    In this paper, we have discussed the application of Zigbee technology. We have shown that a single remote controlled device can control different devices with different application. The experiment performed by us shows the simulation of zigbee within the range of upto 75 meters. The remote controller uses zigbee to control devices like air-conditioner, lights, automatic curtains, garage-shutters, music-player, etc. The simulation of zigbee technology has been done using QualNet software version 6.1. We have shown the experimental working of full-function device and reduced-function device in zigbee technology. The throughput and calculation of the simulated result have also been shown.

  • 802.15.4 Wireless Sensor Network
    2nd European Conference & Exhibition on Integration Issues of Miniaturized Systems - MOMS MOEMS ICS and Electronic Components, 2008
    Co-Authors: Alfredo Maglione, Nicola Battisti
    Abstract:

    Optoi is developing new projects regarding smart sensors for Home and Building Automation. The particular interest in wireless protocols has brought the company to be ready with its first product line at 2.4GHz. Optoi WSN consists in two 802.15.4 standard compliant 2.4GHz elements, which can build a wireless sensor network. The Z-slave element is able to communicate its sensor's values to the master. Zslave is a RFD (reduced function device) stand alone. Any RFD can be connected to a coordinator to build a star network. Each network needs at least one coordinator as a controller (i.e. Z-master) and it can reach up to 20 points. In order to extend the network, more coordinators can be connected to each other in Modbus standard (the coordinators become slaves in Modbus protocol, a master Modbus is needed like an industrial PC for example).

  • The Wireless Sensor Network Construction of the Photovoltaic Power System Zig Bee
    Procedia Engineering, 2011
    Co-Authors: Xu Xiaoli, Wang Huan
    Abstract:

    Abstract Solar photovoltaic power generation is a way to utilize the solar energy. Power station monitoring system is ought to be established to maintain the safe and reliable operation of the photovoltaic system and to detect and solve the malfunctions promptly. The monitoring data of the photovoltaic power monitoring system is composed of environmental data, the related data of photovoltaic battery array and relevant data of inverter. The collection, preprocessing and wireless transmission of data are done by ZigBee, the wireless sensor network. The wireless network panel point of ZigBee is divided into FFD (Full Function device) and RFD (Reduced Function device), each of which has its own functions. It can conveniently collect surrounding environment information and status data of photovoltaic power on unattended conditions by ZigBee.
