Denial-of-service in wireless sencsor networks: Attacks and defenses

Wireless sensor networks (WSN) denial-of-service (DoS) attacks targeting energy-efficient protocols are studied by exploring network characteristics and adoption of general security mechanisms to account for these characteristics. Security Protocols for Sensor Networks (SPINS) provide broadcast authentication, two-party authentication, and data confidentiality using symmetric cryptography. DoS attacks focus on physical aspects of sensor node with an acoustic barrier to reduce network sensitivity. Medium Access Protocols (MAC) are focused for DoS as they control the functionality of the transceiver, which consumes more energy than any other component on wireless sensor platforms. An attacker achieves DoS by jamming or destroying the key network nodes by header encryption technique, to analyze the volume of traffic in various portions of the network.
