Developing a Group-based Security Scheme for Wireless Sensor Networks

—This paper presents a group-based security scheme for distributed wireless sensor networks. The scheme is proposed with 3-types of entities: one or more base stations, Y number of group dominator nodes, and N number of ordinary sensor nodes. We model the group-based deployment using Gaussian (normal) distribution and show that more than 85% network connectivity can be achieved with the proposed model. The small groups with pre-shared secrets form the secure groups where group dominators form the backbone of the network. The scheme is devised for dealing with sensory data aggregated by groups of collocated sensors; i.e., local sensed data are collected by the dominating nodes and sent an aggregated packet to the base station via other group dominators. The scheme is shown to be light-weight, and it offers a stronger defense against node capture attacks. Analysis and simulation results are presented to defend our proposal. Analysis shows that robustness can significantly be improved ...
