Research on wireless sensor networks (WSNs) is at an early stage and, to date, practical experience with deployment has been very limited. The focus of past research has been on fundamental design issues, especially on optimizing the use of scarce energy resources in battery-powered devices. Published studies show relative comparisons between alternative approaches, but there has been a dearth of research on absolute performance in WSNs. In particular, very little attention has been paid to situations where performance assurances are desirable, especially in regard to timeliness and dependability. However, many future WSN applications such as plant automation, vehicle control or health monitoring will demand a degree of certainty in their ability to respond to external stimuli. This proposal will conduct strategic research that will enable the use of WSNs in industrial environments where performance assurances are critical. Key innovations will be produced to enhance the performance and management of WSNs beyond the current state-of-the-art. Working with industry partners, the viability of the research will be demonstrated and evaluated in a large-scale industrial setting.
