Performance Enhancement of Multicast Network with PRSF Strategy under Secrecy Constraint

This paper investigates the secure outage performance of multicast channels with partial relay selection and forward (PRSF) strategy over dense fading environment. Analytical model is developed to ensure secure message delivery by a source to several destinations via multiple relays under PRSF scheme. The expressions of the secrecy performance indices: ergodic secrecy multicast capacity, probability of non-zero secrecy multicast capacity and secure outage probability are developed in closed-forms. Afterwards, analytical results are compared to those of simulation one for justifying the validity of the derived expressions.
