We present GS, a distributed algorithm for scalable self-configuration and self-healing in multi-hop wireless sensor networks. The algorithm enables network nodes in a 2D plane to configure themselves into a cellular hexagonal structure where cells have tightly bounded geographic radius and the overlap between neighboring cells is low. The structure is self-healing under various perturbations, ...

There is a growing interest in the area of self-healing systems. Self-healing does however impose considerable demands on system infrastructures—especially in terms of openness and support for reconfigurability. This paper proposes that the selfawareness inherent in reflective technologies lends itself well to the construction of self-healing systems. In particular, the paper examines the suppo...

Importantly, increased automation is changing the way physical, virtual and cloud environments are managed. Outages caused by human error can have a high impact on business, and as a result companies have automated as much as possible to eradicate human errors. In fact, some companies have added penalty clauses to provider service level agreements (SLAs) to cover human-induced errors. Moreover,...

Wireless sensor networks (WSNs) have received tremendous attention over the past ten years. In engineering applications of WSNs, a number of sensor nodes are usually spread across some specific geographical area. Some of these nodes have to work in harsh environments. Dependability of the Wireless Sensor Network (WSN) is very important for its successful applications in the engineering area. In...

Self-healing and self-adaptive systems dynamically react on changes in the environment. They enable software systems to adjust to new conditions and work optimally even in unstable environments. However, such systems have to cope with an ever increasing complexity and size of software systems. In order to handle such systems, models are an efficient means for analysis, control, and documentatio...

Self-healing epoxy waterborne polyurethane (EWPU) was prepared by embedding mercaptan-contained microcapsules. Once microcracks expanded, microcapsules ruptured and mercaptan released to the valley of microcrack realize self-healing.
