Preventing Attacks From Eavesdropper Using Hmac Protocol in Wireless Sensor Networks
A Wireless Sensor Network (WSN) is composed of numerous small sensing devices with limited communication range. The sensors collect data from the environment and report them to the sinks. With the promising sensing and wireless technologies, sensor networks are expected to be widely deployed in a broad spectrum of civil and military applications. Location information of the sinks, the sensors, and the objects being tracked are very important in sensor networks. Protecting location privacy in sensor networks is crucial considering different kinds of attacks that may disrupt the normal function of the networks.
