Abstract:
Smart City is an environment where different kinds of devices are interconnected to
provide the city occupants with up to date information. Smart city environments are
considered important for future urban development. The sensing and monitoring of the
heterogeneous environment conditions is the major role of a smart city. This paper
presents a framework for creating a personalized smart city environment using Wireless
Sensor Networks (WSN). This framework is able to handle heterogeneous conditions
over the Internet and intercommunication among nodes, providing a base for Internet Of
Things (IOT). The framework compromises wireless sensor nodes for sensing
environment conditions, a hybrid gateway for coordinating the wireless network with an
Internet accessible application server and a user interface giving remote accessibility to
the WSN. The WSN is developed using mesh-tree topology. So as large number of
wireless sensor nodes can b distributed as routers or end devices. The developed
framework is capable of monitoring three kinds of signals, on demand data, periodic
signals and emergency signals. The proposed framework is modelled and tested using
five wireless sensor nodes so as each node can be measured air quality, flame, sound,
light and temperature.
