Relational Model and Improvised DSR Assisted Framework for Secure Wireless Communication

Wireless communications offer a wide range of application with cost- effective communication establishment used in both commercial and domestic purpose. Owing to the presence of decentralized environment in Wireless Communications, it is quite a potential issue for monitoring the regular behavior of any wireless node while performing data propagation. The proposed study states that a wireless node in wireless communication environment plays a role of either normal node or malicious node with completely two different polarities of intention. However, the essential concern is mainly towards the selfish node, which is basically a normal node and owing to certain reason their behavior comes under suspicious zone. Irrespective of various forms of security attacks, identifying malicious node behavior is the most challenging security concern in wireless communication, which has yet not received a proper security solution. The proposed work presents a novel idea of security towards resisting adversarial impact of selfish node and routing mis-behavior present in wireless communications environment. The 1st-framework introduces a retaliation model where a novel role of node called as an auxiliary node is introduced to cater up the routing demands along with security demands. This module performs identification of a malicious routing mis-behavior based on evaluation carried out for the control message being propagated to the auxiliary node. The 2nd-framework further introduces a group friendly architecture where a probability-based modelling is carried out considering various possible set of actions to be executed by normal and selfish node. The model also presents a solution towards security threat prevention by encouraging the selfish node to perform cooperation. The study outcome is benchmarked with existing technique to see that proposed system offers a good balance between security performance and data transmission performance in wireless communication. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
