Wireless sensor networks are becoming more and more popular in a widespread number of applications related to monitoring environments, structures, and machinery. Wired monitoring systems are currently widely adopted in industrial settings due to their reputation and history in performing to established standards. In order to explore the field of low-power wireless industrial sensor network monitoring applications, experimental work has to be done in numerous environments. In this thesis, there is a focus on the design and development of hardware and software for such a purpose. Network coordinator devices capable of Internet connectivity over Ethernet, battery-powered sensor nodes equipped to measure acceleration and temperature, and accelerometer boards were designed and produced for the application. The software on the devices was developed as an adaptation of an open-source operating system, Contiki, and explores Internet version 6 connectivity. The goal of the work on this system is to develop a wireless sensor network platform for future research in the areas of sensor testing and industrial monitoring. Two test networks were created with the aforementioned devices to demonstrate their functionality. One network was formed in a laboratory environment where network performance could be judged and tests could be run efficiently. The network contained nine end-nodes and one gateway, and ran for 49 days with an average packet reception rate of 98.2%. The second network was setup in a compressor room on Queen’s University campus; the topology included four end- ii nodes and one gateway. The network observed continuous data collection for 36 days with an average packet reception rate of 86.6%. The battery replacement cycle for the end-nodes was calculated in-laboratory to be 1.36 years; the platform would be suitable for use in a laboratory setting for future research but more work on the system is necessary to improve performance in an industrial environment. The compressor room case study continues to run as a subject of future work. Software changes expected to improve the performance of the system will be uploaded to the devices as they are developed. Such software changes may improve the system’s efficiency and result in an improved battery replacement cycle length.
