IMPLEMENTATION OF A LOCATION-BASED WIRELESS SENSOR NETWORK

Wireless sensor networks (WSNs) are distributed in various areas, including military, industrial, and consumer applications, for tasks like surveillance, environmental monitoring, or machine control. They are an emerging technology with heavy investment and many hours of research going into the topic, and because of this many WSNs have already been created and dispersed. This paper proposes the implementation of a WSN with environmental monitoring features and with the added feature of localization of nodes in the network. The localization feature performs single hop distance measurement using peer-to-peer (P2P) measurements between the mesh nodes in a Bluetooth mesh network. This gives selected nodes in the WSN the ability to locate other nodes of interest across the network and provide the estimated distance between the two nodes.
