Enhancing Critical Site Security with Wireless Sensor Networks

This document discusses the application of wireless sensor networks (WSNs) in enhancing security at critical sites. It covers various types of sensors including proximity, audio, video, temperature, humidity, and motion sensors. The document outlines deployment methods such as individual placement and zone placement, as well as data transport techniques, both wired and wireless. It highlights common difficulties such as power, security, environment, and interference issues, while proposing solutions for effective sensor placement and data transmission.
