Secure Two-Way Relay Network with Joint Relay and Jammer Selection

Problem Definition

Problem Description: The problem of secure data transmission in two-way relay networks with the presence of an eavesdropper poses a significant challenge in wireless communication systems. In traditional methods, the selection of joint relay and jammer nodes is crucial in enhancing the security of the network. However, the effectiveness of jamming schemes in different scenarios, such as randomly distributed intermediate nodes versus clustered nodes, needs to be investigated further. The conventional relay mode with amplify and forward protocol provides data transmission from the source to the destination. Intentional interference is created upon the eavesdropper by using additional nodes as jammers in different communication phases.

It is observed that in scenarios where intermediate nodes are distributed randomly, the non-jamming scheme outperforms the jamming scheme. Conversely, in scenarios where intermediate nodes are clustered closely together, the jamming scheme is less effective compared to non-jamming. To address these challenges, a hybrid scheme that switches between jamming and non-jamming modes is proposed. The objective is to optimize the joint relay and jammer selection to enhance the security of two-way relay networks against eavesdroppers. The hybrid scheme aims to improve the efficiency of data transmission while mitigating the vulnerabilities posed by different network configurations.

The effectiveness of the hybrid scheme is evaluated to demonstrate its superiority over conventional relay and jamming schemes in secure data transmission in two-way relay networks.

Proposed Work

The proposed work titled "Joint Relay and Jammer Selection for Secure Two-Way Relay Networks" explores the concept of joint relay and jammer selection in two-way cooperative networks with a focus on enhancing security against eavesdroppers. The algorithm considers the use of two or three intermediate nodes to improve security measures. The first node acts as a conventional relay using the amplify and forward protocol to assist in data delivery, while the second and third nodes function as jammers to create intentional interference against malicious eavesdroppers. A comparison between jamming and non-jamming schemes reveals that non-jamming is more effective when intermediate nodes are distributed randomly, while jamming is less effective in clustered scenarios. To address this issue, a hybrid scheme is proposed to switch between jamming and non-jamming modes based on the network configuration.

The results indicate that the hybrid scheme is more efficient and effective in improving security in two-way relay networks.
