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.
