||Developing a Robust Protocol for Wireless Fire Alarms
This project deals with the development of a communication protocol
used to ensure a robust and reliable communication in a wireless fire
Based on an analysis of the scenario consisting of wireless
detectors communicating with gateways which are connected to a
central unit via a cabled network, the communication technologies
are chosen. The ZigBee protocol is chosen as the wireless
communication standard, and the cabled network is simulated using
An application layer protocol is developed on top of the ZigBee
protocol, with high availability, reliability, robustness, and low
power consumption as primary objectives.
A detector is designed and implemented using a TI-430F149
microcontroller and a gateway and central unit are merged and
implemented on a Linux PC. Two Adcon Addlink 868 MHz ZigBee based
radio modems are used as Wireless links.
The designed protocol is verified using UppAal to ensure that no
live- or deadlocks exist, and the required specifications dictated
by EN/DS standards are met.
The protocol software is implemented on a system consisting of one
detector and one gateway/central unit.
Through testing it became evident, that the developed protocol can
provide robust and reliable communication between detector and
central unit, with an error rate of less then 10exp(-9)
