Secrecy outage of a multi‐relay cooperative communication network with accumulation of harvesting energy at relays

Average SER analysis of two‐hop WP DF relay system under κ−μ shadowed fading

“…Hence, the MGF of 𝛾 SR can be obtained by substituting (13) in (15). On interchanging the order of summations and integration the MGF is given by…”

“…It is shown below that these two terms converge with an increase in N . First, we proceed with the term  1 (N ), which is expanded using relation (a) n = Γ(n + a)∕Γ(a) and (A.10) as 15) where a = Γ(𝜇)∕(Γ(m) 2 ) and b = N (N + 1). Ignoring the term o(|N | −2 ) and applying first-order differentiation on both sides of (A.15) with respect to N , then using (A.11) followed by rearranging the terms, we get…”

“…Information‐theoretic analysis of a three‐node AF relay system with RF‐based EH at the relay node is considered. Subsequently, work on EH at relay node(s) has been extended to systems like parallel relaying [4], multi‐hop relaying [11], two‐way relaying [12, 13], MIMO (multiple‐input multiple‐output) [14], physical layer security [15, 16] etc. Extensive research has been done on the WP relay system with EH at relay node(s).…”
