Simulation Results

The outage probability of the channel state information assisted opportunistic amplify-and-forward relaying system with a maximal ratio combining receiver at the destination is investigated, and the exact outage probability expression is presented. The asymptotic equivalence of two different opportunistic relay selection criterions (maxSNR and maxmin) is proved too. Monte Carlo simulation results show that the derived expression is in excellent agreement with the outage probability of systems based on the maxSNR criterion, and also provides a good approximation to the outage probability of systems based on the maxmin criterion.

Secrecy Outage

We study the secrecy outage probability of the amplify-and-forward (AF) relaying protocol, which consists of one source, one destination, multiple relays, and multiple eavesdroppers. In this system, the aim is to transmit the confidential messages from a source to a destination via the selected relay in presence of eavesdroppers. Moreover, partial relay selection scheme is utilized for relay selection based on outdated channel state information where only neighboring channel information (source-relays) is available and passive eavesdroppers are considered where a transmitter does not have any knowledge of eavesdroppers’ channels. Specifically, we offer the exact secrecy outage probability of the proposed system in a one-integral form as well as providing the asymptotic secrecy outage probability in a closed-form. Numerical examples are given to verify our provided analytical results for different system conditions.
