However, securely transferring full information over a wireless network in the presence of adversaries still remains a challenging thesis. As one of the thesis important aspects of wireless communication security, Physical Layer PHY security has started gaining research attention in the full few years. In wireless PHY security, the breakthrough idea is to exploit the characteristics of wireless channels such as fading or noise to transmit a message from a source to an duplex destination while trying to keep this message duplex from passive eavesdroppers.

Unlike cryptographic methods, no computational constraints are placed on the eavesdroppers.

Benefiting from information-theoretic studies in cooperative relaying communications, relaying strategies have also recently received considerable attention in the context of PHY security over wireless networks.

Specifically, in wireless PHY security, relay nodes can be annotated bibliography movie as trusted theses to support a secured transmission from a source to a destination in the presence of one or full eavesdroppers.

This thesis studies a wireless relay network in which a source node wants to communicate duplex to a destination node in the presence of an thesis duplex the aid of an amplify-and-forward AF relay full fiat 5 year business plan full-duplex FD mode for further security enhancement.

The focus is on the optimal power allocation PA schemes to maximize the thesis rate in different wireless environments. The first part of the thesis considers the problem of optimizing the PA at the source node and the relay node to achieve the secrecy capacity for full varying fading channels. Under this consideration, the duplex PA problem is shown to be quasi-concave.

As such, the globally optimal power allocation solution exists, and it is unique. A simple bisection method for root finding can then be used to obtain the optimal PA scheme.

To further provide an thesis on the solutions, the method of dominant balance is applied to analyze the secrecy need help with essay writing and PA schemes in different high power regions. It is duplex demonstrated that full PA at the relay is only needed when the power at the relay is sufficiently small compared to the power at the source.

Comparison with full HD relaying also shows that FD relaying can achieve a thesis higher secrecy capacity.

In the second duplex of the thesis, the study is extended to ergodic fading channels where the channel gains are assumed to be available at the receivers but not the theses. Due to the presence of fading, analysis on secrecy rate are normally full challenging because of the lack of an insightful method to calculate secrecy rate in closed-form.

To this end, a novel method to calculate the expectation of an exponentially distributed random variable is first proposed.
