Study and Analysis of Key-Predistribution Schemes Based on Hash Chain for WSN

In recent years, Wireless Sensor Network (WSN) has become a leading area of research. WSN is ad hoc, without infrastructure wireless network that connects a huge number of wireless sensors. WSN consists of multiple sensor nodes which have limited processing speed, storage capacity, communication bandwidth and base stations. They can be thought of as the network’s “sensing cells” and “brain”, respectively. They are emerging as a better technology in the future due to their large range of applications in surveillance and people-related domains. This paper proposes a study and analysis of hash-based key predistribution for a better understanding of the uses of key predistribution or random key predistribution over the wireless sensor network to prevent the makers and also provide better connectivity, lower storage overhead, lower communication overhead and less computation complexities.
