Location Privacy in Wireless Sensor Networks
Today all kinds of ubiquitous systems, led by wireless sensor networks, can be seen as an unprecedented privacy risk given their ability to collect information on quantities and situations so far unsuspected. There is therefore an urgent need to develop mechanisms to ensure privacy in sensor networks. Location Privacy in Wireless Sensor Networks focuses on location privacy, by which an attacker might determine the source and destination of communications with simple techniques. This poses a serious threat as the attacker might use this information to reach the assets or individuals being monitored or even to destroy or compromise the whole network. This book will aid in the protection against this serious privacy threat.

Location Privacy in Wireless Sensor Network Using Reciprocal Protocol
Abstract: Location privacy has been one of the greatest threats in wireless systems. The utilization of k-anonymity in Wireless Sensor Networks (WSNs) protects the location privacy. This characteristic feature enables the server to receive aggregate k-anonymized locations of internally connected sensor nodes. These k-anonymized locations are comprised of, a minimum of k persons. Nevertheless, an intruder model is used to high point the readiness of privacy risks in overlapping aggregate locations because an adversary can deduce the overlapping areas contained in an area with less than k persons whose requirement violates k-anonymity privacy. Hence, a reciprocal protocol (REAL) is used for establishing location privacy in Wireless Sensor Networks (WSNs). The sensor nodes organize a group of non-overlapping areas and k-anonymized locations into sensing areas. To overcome the privacy threats in REAL, a process state transition is designed with a time delay mechanism that provides accuracy of the messages received and a locking mechanism is designed to enhance reciprocity property. The generation of an error-free query reply and securing location privacy and decreasing computational and communication costs is achieved by the experimental analysis of the REAL protocol.
