Wireless Sensor Networks (WSNs) have attracted tremendous attention of the research community in recent years. Security becomes one of the major concerns when there are potential attacks against sensor networks. Many services in security, such as authentication and key management, are critical to ensure the normal operations of a sensor network in diverse applications and environments. Thus, familiarity with the current research in this field will benefit researchers greatly. With this in mind, the authors survey the major topics in WSNs security, and present the main solutions in the sensor security, classify many of the current attacks. They also discuss their proposal architecture based on multi agent platform for ensuring robust security, without key management, in wireless sensor networks with lower energy consumption.
