A Cluster Tree Based Model for Secure Data Retrieval in Military using Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) can be used in military environments such as a battlefield tracking the enemies. One of the challenging issues in this scenario is enforcement of authorization policies and the policies update for secure data retrieval. CP-ABE is using efficient and secure data retrieval method for decentralized DTNs. However implementing Cipher text-Policy Attribute – Based Encryption (CP-ABE) in decentralized DTNs where the key authorities might be compromised or not fully trusted. In this paper we propose a secured data retrieval method using Cluster Tree Based Model proposes grouping the slave nodes, where each node has an individual group head. The cluster model provide key to group head and the group head will distribute the key to all members and implementing Position-based Aggregator Node Election protocol (PANEL) is a position-based clustering routing protocol for WSNs. The main goal of PANEL is to elect aggregators, i.e., CHs. PANEL protocol are used to balance the network node load pressure and reduces the communication load.
