Framework for a Self-managed Wireless Sensor Cloud for Critical Event Management

Abstract

Wireless sensor networks (WSNs) can be widely used for managing various scenarios existing in social, industrial and numerous environmental management systems. They have been widely used in environmental monitoring and management applications and have also found application in disaster management scenarios. One of the greatest problems faced by the scientific community in organizing data collection through sensor networks in areas of disaster is the disorder and destruction brought about in the communication systems prevailing in such situations. In this paper, a scientific study of the various scenarios that could occur post-disaster and the various housekeeping functions each sensor node would adopt as part of the self management requirement is provided. We also present a sensor task management framework that could be implemented to provide a low energy consuming, reliable network for WSNs deployed for critical infrastructure management.Keywords: self-managed wireless sensor cloud, critical event management. Related WorkWireless sensor networks used for monitoring applications can be prone to various events like nodes dying, topology reconfiguration, loss of connection to the base station etc. Depending on various events that could occur during a WSN deployment, elements that could be said to contribute to the design of a WSN are protocols, data fusion / aggregation techniques, topology management and methods of deployment. Protocols that are used in WSNs can be categorized as network / routing, transport and MAC protocols. There have been several network protocols designed to address the issue of connectivity establishment. According to the authors of [1], LEACH
