ABSTRACT
Wireless Sensor Networks have come to the forefront of the scientific community recently and it consists of small
nodes with sensing, Communications and computing capabilities. The Wireless Sensor Network Systems can be
applied to monitor different environments ranging from military to civil applications. It is observed that different
protocols necessary for smooth functioning of the network system are highly application specific. Current WSNs
typically communicate directly with a centralized controller or satellite. In this paper we survey the different
research challenges in Wireless Sensor Networks and purpose of various research Challenges activities is the
development of a framework, which is radically simplifies the development of software for sensor network
applications and characteristic Features of Sensor Networks.
Keywords: - Wireless Sensor Network, Research Challenge, Characteristic Features
