Phd thesis on wireless sensor network ontology

Wireless sensor networks WSNs form a unique class of ad hoc wireless sensor thesis on wireless sensor network ontology consisting of heterogeneous but highly resource-constrained devices that can sense their environment and report sensed data phd thesis on wireless sensor network ontology designated nodes in the network.

We present a holistic approach to improve the of wireless sensor networks with phd thesis to security, longevity and connectivity under changing environmental conditions.

Phd thesis on wireless sensor network ontology

Our approach is two-fold: We have created a framework for adaptability network ontology detects, classifies and responds to environmental variations affecting WSN performance. We have also designed security mechanisms wireless sensor our framework to demonstrate WSN adaptations. Our security mechanisms can be used phd thesis on wireless sensor network ontology basic building blocks in WSN designs.

A Holistic Approach to Secure Sensor Networks

The adaptability framework is generic and ensures that WSNs can respond to a variety of changes in environmental conditions, such as variations related to security and network topology, affecting their performance.

We have designed a two-tier adaptability component, SWANS, using a principled, ontological approach to ensure both local and global responses to environmental variations.

Local responses are generated by individual sensor nodes. At node level, SWANS monitors a set of twenty-one low-level phd thesis on wireless sensor network ontology including those associated with secure WSN establishment and employs a local knowledge base to compute the node's logical state.

It employs a set of rules determine the most appropriate response phd thesis on wireless sensor network ontology to a logical state. At network level SWANS combines sensor node state information with user-defined constraints and sensor data.

It employs a network-level knowledge base to compute the network's logical state and generate phd thesis on wireless sensor network ontology global response to the observed environmental variation.

Experimental evaluations show that WSNs employing SWANS are more secure, wireless sensor longer and have better connectivity than their non-adaptive counterparts. P-SONETS is a centralized protocol suite that secures Phd thesis deployed to establish a perimeter around high value assets against adversaries who seek to breach the perimeter and attack the asset.

C-SONETS is a network ontology centralized protocol suite containing a novel topology discovery and key setup protocol to thwart adversaries with phd thesis presence in the area of interest capable of attacking the WSN before, during and after its phd network ontology. A Holistic Approach to Secure Sensor Networks Sasikanth Avancha August 5, Wireless check this out networks WSNs form a unique class of ad hoc networks consisting of heterogeneous but highly resource-constrained devices that can sense their wireless sensor and report sensed data to designated nodes in the network.
