Abstract

Wireless Sensor Nodes in military situations, for example, a war zone or an unfriendly locale are liable to experience the ill effects of discontinuous system network. Objective: To design an efficient data recovery scheme for Decentralized DTNs in military environments, based on CP-ABE methodology, making Security the utmost prioritized characteristic. Analysis: Latest Innovations in Disruption Tolerant Networks (DTN) are getting to be effective arrangements, that permit mobile devices carried by military personnel to correspond with one another and access the classified data or to command effectively by manipulating the independent-autonomous repository nodes. Out of these, the most difficult issues in the situation are the authorization strategies and those approaches' improvisation for secure data recovery. Methodology: Cipher text Policy-Attribute Based Encryption (CP-ABE) is a promising cryptographic technique to address the access authority issues. The issue of applying CP-ABE in decentralized DTNs presents a few security and protection challenges like attribute revoke, key security, and regulation of attributes issued from distinct authorities. So, we implement CP-ABE along with 2PC (Two Phase Commit) protocol and where numerous key authorities deal with their attributes autonomously to overcome the above mentioned challenges. Findings/Improvements: We implement the proposed System as a stand-alone application in Eclipse IDE. We've been successful in implementing this system to achieve the security requirements we've been discussing at length in the paper and we've demonstrated how to recover the data in very hostile military environments in an efficient and a secured manner.

Abstract

Because of its huge scale and restrictions on scope of communication, a Wireless Sensor Network (WSN) generally depends on multi-hop transmissions to transmit a data packet along a succession of storage nodes. It is of key significance to estimate the forwarding nature of multi-hop routes and such data might be used in developing dynamic and economical routing methodologies. Objective: To develop a scheme which eases the determination of Cluster Heads (CH) in a WSN, which inturn would enhances the quality of path management. Analysis: Existing measurements for the most part, concentrate on evaluating the connection link performance among the sensor nodes while ignoring the forwarding abilities inside them. Recent studies demonstrate that the nature of forwarding inside every wireless sensor node is equally essential component that adds to the path quality in data transmission. Methodology: We propose a methodology to reduce the overhead by developing an efficient scheme for selecting a Cluster Head (CH) in each cluster to represent all the other nodes in the cluster. This CH will be responsible for representing the entire Cluster viz., To determine the routing path ,To detect the malicious nodes (Attacker Node) in each cluster, etc., which eventually eases the task of determining the forwarding path, in other words, enhancing the forwarding path quality. Findings/Improvements: A stand-alone application had been developed for this proposed system in Eclispe IDE and the results we obtained has proved that the proposed methodology ,when applied can achieve the required forwarding path quality management in WSN by evaluating both the connection link performance and also the forwarding abilities inside a sensor node.
