Key management scheme in WSN based on grid deployment model

Abstract

A new key management scheme based on equilateral triangle network deployment model in wireless sensor networks is proposed in this paper. It combines the t-order binary polynomial model with the characteristics of node deployment, so the entire network is divided into several mutually non-overlapping equilateral triangle units and each pair of adjacent units adopt the same key allocation algorithm. The analysis and simulation results show that our scheme can not only keep a high level of network secure connectivity probability, but also improve the node anti-capture attack capability while reducing the consumption of node storage capacity. © Springer-Verlag Berlin Heidelberg 2012.
