Abstract: Wireless Sensor Networks (WSN) have proved to be useful in applications that involvemonitoring of real-time data. There is a wide variety of monitoring applications that can employWireless Sensor Network. Characteristics of a WSN, such as topology and scale, depend uponthe application, for which it is employed. Security requirements in WSN vary according to theapplication dependent network characteristics and the characteristics of an application itself.Key management is the most important aspect of security as some other security modulesdepend on it. We discuss application dependent variations in WSN, corresponding changes inthe security requirements of WSN and the applicability of existing key management solutionsin each scenario.
