Wireless Network Security

Wireless Sensor networks (WSN) termed as the dominant technology trends in the coming decades and also plays a very important role in our daily life applications such as remote environmental monitoring and target tracking. It is an emerging technology and one of the most exciting and challenging research domains of our time. The sensing technology merged with a processing power and wireless communication creates beneficial for being exploited in affluence in future. They have a great potential to be utilized in wide mission critical applications such as, military monitoring and health care’s which are very highly sensitive information which makes security in these special networks a crucial concern. In addition, of wireless communication technology runs into a variety of security threats. Here, In this paper, we present a survey of concerned security issues in WSNs and also its various threats and attacks in WSNs. And it’s basic Security Schemas in WSNs. And finally, we conclude the paper delineating the research challenges and future objectives towards the research in wireless sensor network devices.
