Security Concepts and Sybil Attack Detection in Wireless Sensor Networks
Due to broadcast nature of Wireless Sensor Networks (WSNs) and lack of tamper-resistant hardware, security in sensor networks is one of the major issues. Hence research is being done on many security attacks on wireless sensor networks. Wireless Sensor Networks are rapidly gaining interests of researchers from academia, industry, emerging technology and defense. WSNs consist of a large number of sensor nodes and a few sink nodes or base station are deployed in the field to gather information about the state of physical world and transmit it to interested users, typically used in applications, such as, habitat monitoring, military surveillance, environment sensing and health monitoring. Sensor nodes have limited resources in term of processing power, battery power, and data storage.
