Repair Assessment of Sensor Node Failures for Activity Detection
نویسندگان
چکیده
Accurate and reliable detection of activities of daily living (ADL) is extremely difficult and it becomes even harder due to sensor node failures caused by hardware degradation, node displacement, inaccurate readings, and environmental changes. Once a fault is detected, we propose to evaluate its severity by using data replay analysis to determine if this fault could have caused errors in the past. This approach significantly decreases the number of necessary sensor repairs and maintenance dispatches.

A Non-MDS Erasure Code Scheme for Storage Applications
This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to reconstruct a lost node, while in MDS erasure codedsystems which are optimal in terms of redundancy-reliability tradeoff, a single node failure isrepaired after recovering the ...
متن کاملBeing SMART About Failures: Assessing Repairs in Activity Detection
One of the main challenges for activity recognition systems is that there are numerous sensors which are likely to move or exhibit failures due to hardware degradation, inaccurate readings, and environmental changes. In this paper, we propose a Simultaneous Multi-classifier Activity Recognition Technique (SMART) that uses application-level semantics to detect sensor node failures and improve th...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
متن کاملRun-Time Fault Management in Wireless Sensor Systems
Software failures in wireless sensor systems are notoriously difficult to debug. Resource constraints in wireless deployments substantially restrict visibility into the root causes of system and application level faults. At the same time, the high deployment cost of wireless sensor systems often far exceeds the cumulative cost of all other sensor hardware, such that software failures that compl...
