Wireless Sensor Networks (WSNs) form a unique class of ad hoc networks consisting of heterogeneous but highly resource constrained devices that can sense their environment and report sensed data to designated nodes in the network. The authors have gone through the number of approaches to improve the performance of WSNs with respect to security, longevity and connectivity under changing environmental conditions. Thereafter they have created a framework for adaptability that detects, classifies and responds to environmental variations affecting its performance. This required framework must be generic and ensures that WSNs can respond to different environmental conditions.
