Security and Challenges for Wireless Sensor Network

Wireless Sensor Network security challenges and defences techniques are presented for protection of authenticity integrity, confidentiality and availability of transmission against malicious wireless attacks. Wide range of Wireless attacks and security threats at different layers. Due to the sensitive nature of the data gathered by many wireless sensor network (WSNs)it is becoming more difficult to protect the data. This paper analyzes security requirements in wireless sensor network and it facing more attacks and threats, we also discuss the open challenges in the Software Defined Network.
