Wireless sensor networks area: security and challenges

Wireless Sensor Network (WSN) is a high potential and emerging technology with a multitude of important applications such as remote environmental monitoring and target tracking. They are used in crisis or critical situations (military use) and have commercial applications such as construction, also in traffic, as well as the surveillance of homes and smart homes and in many other situations. Wireless sensor networks are a major security problem these days. This level of security has been made weak or rendered obsolete by the possibility of some sort of attack; the innate power and recall limit of the sensor nodes win the usual impractical security solutions. Wireless interface team, they communicate with each other forming a network. This article sheds light on security issues in WSN networks, discuss the know-how of sensor network security research and also future research angles
