Adaptive security approach for wireless sensor network using RSA algorithm

Abstract

A type of distributed and self-regulating network is the wireless sensor network (WSN). The sensor nodes have limited computing capabilities, memory, battery power are needed to ensure a strong security design. In this paper, an adaptive cryptographic scheme for WSN that is operating on routing ad hoc on-demand vector routing (AODV) protocol. The adaptive term refers to the adopted mechanism between heavy and light asymmetric cryptography techniques of RSA. The heavy technique adopts the complete version of RSA algorithm, while the light one considers a reduced complexity version. This is to control the security operation over the included nodes even with low power ratio. In various case studies, the proposed scheme is checked and the result obtained shows the high efficiency of results in terms of protection guarantee.

Intelligent collection system of human resource information based on clustering algorithm

“…Its advantage is that the algorithm has high performance, because its time complexity is 0, where n is all the data, h is the number of clusters, t is the number of iterations of the algorithm (t <n) and the geometric properties of the data all affect the process of the K-means algorithm. Selection of the initial value optimization algorithm, Bradley optimization algorithm, Lichuan genetic algorithm , proposed many optimization algorithms, such as combining antivirus with K-means optimization, o re algorithm, etc [1][2].…”

Automatic delivery-scam prevention using Raspberry-Pi

“…This model will definitely assure safe delivery especially for high budget products like electronic equipment and it can be designed in various sizes suiting Indonesian J Elec Eng & Comp Sci ISSN: 2502-4752  the majorly ordered expensive products [21]- [23]. A survey has been conducted among hundreds of people including customers faced scam issues, delivering agencies and workers of the delivering companies [24]- [26]. The result Figure 7 showed that most people think that this system could prevent scam in product delivery and prove beneficial to customers as well as to the companies.…”
