Wireless Site Surveillance System

Abstract [en]

In order to monitor telecommunications base stations more closely more and new sensorsare needed. Installing new sensors can however prove difficult and costly since it willmost probably include installing wiring to and from these sensors.This master thesis examines the possibility to use existing wireless technology to con-nect such sensors within a base station and to a broader surveillance system. A smallsensor node is designed, built and tested.The Mulle wireless platform is used to collect sensor data and communicate over Blue-tooth. The receiving end is an Internet connected, PAN-GW enabled unit running pythonand acting site controller.Communication is kept secure with pre-shared secrets and AES encryption, three-wayhandshakes, sequence numbering and heartbeats.Temperature and humidity is measured at very low power for proof-of-concept. Thesite controller communicates with OSS when preset thresholds are crossed.Heartbeats and watchdog timers makes the system robust and reliable.It is shown that the Mulle platform is well suited for implementing wireless batterypowered sensors using Bluetooth communication.
