A Survey of Security Challenges in Wireless Sensor Networks and Their Secured Protocols

the phenomenal growth of Wireless Sensor Networks (WSNs) over the past few years has attracted significant research and development efforts in academic and industry. They were first used by the military for surveillance purposes and have since expanded into industrial and civilian uses such as weather, traffic control, polluting and healthcare. Due to the sensitive nature of the data gathered by many WSNs it is becoming critical that this data be protected. In this survey, a comprehensive list of major known security threats within wireless sensor networks (WSNs) has been presented. Also, various secure protocols and various solutions to combat attacks have been discussed. The different security protocols were compared and future research directions pertinent to WSNs security have been introduced. We hope this survey provide the insight for future research efforts in the WSN security.
