Efficient and Secured Route Management Scheme Against Security Attacks in Wireless Sensor Networks

In this modern and technological world, everyone needs to communicate globally without any limitations in connectivity. It can be achieved using a Wireless Sensor Network (WSN) environment, which provides an excellent gateway to perform communication globally without any intervention. However, security is the most vital concern to take care of with such communication norms. The clients need to communicate their data between source and destination entities require high security and privacy to attain a successful communication. The principal objective of this paper is to establish a robust and flaw-free communication model with strong networking abilities under the management of numerous nodes present in the wireless network region. In this paper, novel communication strategies are introduced to provide efficient and secure communication between entities, in which the communication robustness is achieved by applying the new scheme, known as Intelligent Channel Aware Reputation Scheme (ICARS). This ICARS allows the entities to perform flaw-free communication between one end and another using Routing Management Norms like Route Request (RREQ) and Route Response (RREP) principles. For enabling the security features, a novel cipher algorithm Modified Rijndael Algorithm (MRA) is introduced. When data is communicating from source to destination, it provides high-level protection, and this approach utilised 256-bit encryption logic to handle the data during communication. This proposed approach of ICARS with MRA eliminates the attacking scenario and robust against the attacks such as Denial-of-Service, Wormhole Attacks, and Blackhole Attacks. The ability of the proposed approach is proved in the resulting section through the following constraints such as enhanced throughput, reduced retransmission ratio, minimised end-to-end delay, improved energy efficiency, and the enhanced Packet Delivery Ratio (PDR).
