Abstract :
The use of Wireless Sensor Networks (WSNs) has got great importance in many applications ranging from home and industrial applications to more sensitive military applications. In mobility context, such applications introduce new technological challenges for security. The resource constrained devices should be protected from various security attacks and provided with secure data communication. To this aim, a proper key management scheme supporting node mobility is required. In this paper, we present an effective key management scheme that can support node mobility in the heterogeneous sensor networks that consists of mobile sensor nodes with few fixed sensor nodes. The analytical and OMNET++ simulation results of our proposed scheme shows that it provides better network connectivity, consume less memory and has better network resilience against attacks.
