Vipin Kumar, Priyanka Ahlawat . Hash Chain based Key Management for Mobile Heterogeneous Sensor Network. International Journal of Computer Applications. 69, 23 ( May 2013), 33-36. DOI=10.5120/12113-8402
Key management is an important issue for wireless sensor networks because sensors have limited resources as memory, processing speed and battery power. Key management is one of the basic building blocks of sensor network security. Many protocol presented before didn’t take much attention on mobility of node. In this paper, we proposed Hass Chain based key management scheme for Heterogeneous networks where Base Station and cluster head are fixed and other node moving around these heads. Compare to other basic key management scheme, proposed scheme increase resilience against node capture as well as consider memory limitations.
