Secure communication design for multi-user peer-to-peer wireless relay networks PROJECT TITLE :Secure Communication design for multi-user peer-to-peer wireless relay networksABSTRACT:During this study, physical layer security techniques are studied for multi-user peer-to-peer relay networks using amplify-and-forward protocol in the presence of an eavesdropper. Two system styles are thought of: the minimum achievable secrecy rate maximisation and the total transmit power minimisation. 1st, considering user fairness, the authors study the max–min achievable secrecy rate problem subject to a total transmit power constraint. Mathematically, the optimisation problem is non-linear and non-convex. They propose a polynomial time algorithm primarily based on the bisection technique to solve it. Second, they study the whole transmit power minimisation problem which aims at minimising the overall transmit power at relays such that individual secrecy rate for every user is satisfied. The whole power optimisation problem is additionally non-convex, therefore they use the comfort technique to transform it into a convex problem which will be efficiently solved by the gradient-based mostly algorithms. Numerical analysis of the obtained secrecy rate and transmit power results shows that the proposed designs will considerably improve the performance of secure wireless Communications.
