Security Architecture Framework and Secure Routing Protocols in Wireless Sensor Networks - Survey

Wireless sensor networks emerging has increased now a days , therefore the need foreffective security mechanisms is essential. Because sensor networks may interact with sensitive data andoperate in hostile unattended environments, it is imperative that these security concerns be addressedfrom the beginning of the system design. we survey the major topics in wireless sensor network securityarchitecture framework includes the requirements in the sensor security, classify many of the currentattacks, listing out their corresponding defensive measures that can be applied, and finally theclassification of secure routing protocols, its design issues and their comparison.
