PROJECT TITLE:

Secrecy Capacity Optimization via Cooperative Relaying and Jamming for WANETs - 2015

ABSTRACT:

Cooperative wireless networking, which is promising in improving the system operation potency and reliability by acquiring a lot of correct and timely data, has attracted considerable attentions to support many services in follow. But, the matter of secure cooperative communication has not been well investigated however. During this paper, we exploit physical layer security to produce secure cooperative communication for wireless accidental networks (WANETs) where involve multiple supply-destination pairs and malicious eavesdroppers. By characterizing the protection performance of the system by secrecy capacity, we have a tendency to study the secrecy capability optimization problem in that security enhancement is achieved via cooperative relaying and cooperative jamming. Specifically, we tend to propose a system model where a collection of relay nodes will be exploited by multiple supply-destination pairs to achieve physical layer security. We have a tendency to theoretically gift a corresponding formulation for the relay assignment drawback and develop an optimal algorithm to unravel it in polynomial time. To further increase the system secrecy capacity, we have a tendency to exploit the cooperative jamming technique and propose a good jamming algorithm to interfere the eavesdropping channels. Through in depth experiments, we have a tendency to validate that our proposed algorithms considerably increase the system secrecy capacity under various network settings.
