The Three Dimensional Node Deployment for Sensor Network

Abstract

A low-power sensor node in WSN requires minimum consumption of energy. It is essential to establish key to reduce the effect when the sensor node is revealed. This paper propose the protocol of pairwise key establishment between sensor node. The proposed method increases the availability by clustering the network in three dimensional, which has smaller number of path and better energy efficiency than the plane allocation. This paper discusses the key management for secure communication between sensor nodes after sensor allocation. We propose the protocol of pairwise key establishment scheme using bivariate polynomial based on cluster in order to safety against attack by revealing of node. The proposed method guarantee the availability by clustering the network in three dimensional, which has smaller number of path and better energy efficiency.
