PAD: Power Aware Key Distribution in Wireless Sensor Network Using Group Configuration Methodology

Abstract

Distributed Wireless Sensor Network (DWSN) is an emerging technology for information gathering and processing. A sensor network consists of much resource constrained sensor nodes. These nodes perform measurements of some physical phenomena, process data, gather reports and send these reports to the central processing unit called Mobile Sink (MS). Such communication must be secure in military surveillance, intelligence and tracking field. Efficient key management technique is essential to provide secure communication. As sensor nodes are battery powered devices, the critical aspects in facing key distribution are how to reduce the energy conception for the components of sensor nodes. Thus, implementing a key distribution algorithm should possess a minimum power conception. The proposed work steps towards greater heights by integrating power module with pairwise key establishment using group configuration methodology. Further, 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. Analytical results of this PAD (Power Aware Key Distribution) show that energy efficiency is increased with sensor nodes while establishing pairwise key using group configuration when compared to existing key pre-distribution techniques.
