Self-Healing is called the ability of a computing component to detect, diagnose and repair localized problems resulting from bugs or failures in software and hardware.[CD-IA-1.1.1][AutonomicVision]
Generic
(domain independent)
Self-Healing is the ability of a system or a SBA to repair itself without
any external intervention.[CD-IA-1.1.1] 
A system is self-healing if is able to recover from a failed component by first detecting and isolating the failed component, and repair or replace the compoent without affecting the application. {SPC:Self-Healing system}
A self-healing enhanced system uses both, adaptation and monitoring techniques provided by the system and integrates them into the loop (c.f., MAPE-K loop [AutonomicVision])
Self-healing, which is linked to self-diagnosing or self-repairing, is the capability of discovering, diagnosing, and reacting to disruptions. It can also anticipate potential problems, and accordingly take proper actions to prevent a failure. Self-diagnosing refers to diagnosing errors, faults, and failures, while self-repairing focuses on recovery from them [M. Salehie & Tahvildari, 2009].

Self-healing system should recover from the abnormal (or “unhealthy”) state and return to the normative (“healthy”) state, and function as it was prior to disruption [D. Ghosh et al, 2007].

Scenarios

  • Wine Scenario: A sensor belonging to the WSN used to observe the vineyard parameters could have faulty behavior. The system could be able to identify the faulty sensor and enact suitable actions.
