Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...

In a quiet way, test methods have evolved. But now the test industry is fast approaching a tipping point where the older, intrusive, hardware-based test techniques must be complemented, supplemented, or outright replaced by newer, software-driven, nonintrusive test technologies. What’s driving this trend is what has always driven the test industry: test coverage. Without it, test engineers look...

This paper provides proof of concept for the newly-approved 1149.6 standard by investigating the first silicon implementation of the test receiver. EXTEST and EXTEST_PULSE tests were applied to functional channels as well as channels with a set of externally-induced hard defects. All valid signals were correctly received, and all defects were detected, thus validating both 1149.6’s anticipated ...
