A Survey on Network Security and Attack Defense Mechanism for Wireless Sensor Networks
The severe constraints and demanding deployment environments of wireless sensor networks make security for these systems more challenging than for conventional networks. However, several properties of sensor networks may help address the challenge of building secure networks. The unique aspects of sensor networks may allow novel defenses not available in conventional networks. In this paper, the authors investigate the security related issues and challenges in wireless sensor networks. They identify the security threats, review proposed security mechanisms for wireless sensor networks.
