Conglomerate Elgamal Encryption-Based Data Aggregation and Knapsack-Based Energy Efficient Cryptosystem in Wireless Sensor Network

Wireless Sensor networks are growing rapidly from the past decade mainly due to its efficiency and Ad-Hoc feature. Further, data aggregation has been extensively employed in WSN that also impact on the data transferring between the sensor nodes. The security issues, data integrity and confidentiality becomes vital during the deployment of sensor network in a hostile environment. The entire network comprise of sensors, base stations, gateways and nodes which are connected for the purpose of digital transmission. Many existing works attempted to address the security issues but lacks to obtain reliable and effective results in terms of parameters like energy consumption, packet to delivery ratio, computational cost, etc. The paper focussed on the primary research area of data aggregation and the mode of transmission in an energy efficient way without congestion. To obtain the objective, an integration of Conglomerate ElGamal Encryption and Knapsack-based AODV(Ad-Hoc. On Demand Distance Vector) energy efficient protocol has been employed and the performance of the proposed system are evaluated. The performance parameters like packet delivery ratio, throughput, estimation of alive nodes and dead nodes for different rounds has been performed in the study. Furthermore, the effectiveness of the proposed system has been compared with state of art methods in terms of residual energy and depicted that deliberates the superior performance of the presented framework.
