Peak: Power efficiency analysis for key distribution in Wireless Sensor Network

Abstract

Secure Distributed Wireless Sensor Network (DWSN) is empowered by using an efficient key management technique. Battery powered sensor nodes faces precarious aspects during key distribution in order to reduce the energy consumption for the components of sensor nodes. Thus, implementing a key distribution algorithm should possess minimum power consumption. The proposed work steps towards greater heights by integrating power module with pairwise key establishment using group configuration methodology. We present an investigation of power consumption using STEM (Sparse Topology and Energy Management) protocol on sensor nodes (SNs) during the pairwise key establishment using graphical tools. Further memory utilization is reduced due to less number of keys generated from group configuration methodology. Analytical results of this PEAK (Power Efficiency Analysis for Key Distribution) show that energy efficiency is increased with sensor nodes while establishing pairwise key using group configuration when compared to existing key predistribution techniques.
