Wireless Sensor Networks: Issues & Challenges?

Wireless Sensor Networks (WSN) are highly distributed self organized systems. The basic idea of sensor network is to disperse tiny sensing devices; which are capable of sensing some changes of incidents/parameters and communicating with other devices, spread over a specific geographic area for some specific purposes like environmental monitoring, surveillance, target tracking etc. By combining sensing technology with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The wireless communication technology inclusion also incurs various types of security threats. This paper provides a survey of Issues and challenges related to Wireless Sensor Networks.
