Self-Healing Wireless Sensor Networks

چکیده
Nowadays wireless sensor networks have found their way into a wide variety of applications and systems with vastly varying requirements and characteristics, but all of them have a common element: faults are a normal fact and not isolated events as in traditional networks. Thus, in order to guarantee the network quality of service, it is essential for the sensor network to be able to detect and heal failures. In this work a failure detection scheme and a service management approach using the autonomic computing paradigm and some concepts of the IT Infrastructure Library (ITIL) will be evaluated. The presented approach aims to employ self-healing services, allowing them to discover, examine, diagnose and react to malfunctions.

Evaluation of an Intrusion Detection System for Routing Attacks in Wireless Self-organised Networks
Wireless Sensor Networks (WSNs) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. However,security is a major challenge for WSNs because they areusually setup in unprotected environments. Our goal in thisstudy is to simulate an Intrusion Detection System (IDS)that monitors the WSN and report intrusions accurately andeffectively. We have thus...

Multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. In this paper, a new clustering based multi path routingprotocol namely ECRR (Energy efficient Cluster based Routing algorithm for improving Reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required QoS ...
متن کاملA mutual-healing key distribution scheme in wireless sensor networks
How to establish secure session keys is one of the central tasks for wireless sensor network communications. General key distribution schemes for traditional computer networks could not be directly shifted to wireless sensor network environments as broadcast messages may be lost due to sensor network internal factors or external attacks. Self-healing key distribution schemes, therefore, have be...
