摘要：A wireless Sensor network(WSN) is a group of sensor nodes cooperating to form a network over a wireless link based on zero fixed network infrastructure. The main idea is to make sensor node cheap and easily deployed every where to create a omnipresent network with smart geographical distribution.WSN become demanding because of its service towards wide range of applications. But constraints are with WSN like ,low computation capability, small memory, limited energy, susceptible to physical capture , lack of infrastructure etc. However along with such constraints, due to operation of sensors round the clock in harsh uncontrolled environment make security as a critical issue and challenge. In this paper I survey the network, different types of attacks, security loop holes ,their consequences and discus the counter measures which will be beneficial for students and researchers in this area .
