A Tiny and Light-Weight Autonomic Element for Wireless Sensor Networks

Traffic Engineering and Maintenance Domains in WDM Carrier Ethernet Networks

“…WSN should self-manages its own restricted resources (memory, communication, processing) to maximize energy when it is placed in environments of difficult human access as well to liberate WSN supervisor as much as possible of doing low level tasks as changing sensor batteries. [6] proposes an Autonomic Sensor Element (ESA) which is a model based on autonomic element of [5] with a MAPE autonomic engine (Monitor, Analyze, Plan, Execute, and Knowledge Base) that has well defined management functions to a WSN node. It was simulated in NS-2 [18] with a monoxide carbon sensor application as managed element.…”

“…In case study of [6], these inputs are employed in crisp rules for a node self-configuration decisions, but, in this present work, these inputs was modeled in 7 fuzzy sets and utilized in 74 fuzzy rules for the same purpose. Example of MIA fuzzy rule: If local and neighborhood relevant data are low and sensing and dissemination intervals are low then sensor interval is reasonable low and dissemination is low.…”

“…In the previous example, sensor interval is inferred as low, then, Plan service gives to sensing rate an augment probability of 20% and to dissemination, an augment probability of 80%. After this, Execution service execute this action and update MIB (Management Information Base) of Knowledge Base MIB, as in [6] study case.…”

“…To validate this proposal, there were developed 4 methods in nesC programming language of TinyOS operating system. ESA [6] which MAPE autonomic engine is based on crisp rules to do self-configuration of sensor node. Its managed element is a simple sensor application which sends local environment temperature and relative humidity to WSN monitoring system.…”

ABSR: An Agent Based Self-Recovery Model for Wireless Sensor Network

“…This method demonstrates that multi-agent empowers sensor platforms with the autonomic property of self-management. Autonomic element(AE) was used in nodes of WSN in [10], which verified that the storage space and energy consumption of AE were limited. In this paper, a self-recovery model, ABSR is presented to realize active monitoring and self-recovery using autonomic computing technology.…”
