From: Dynamic of a Delayed Predator-Prey Model with Application to Network’ Users’ Data Forwarding

System dynamic over time when the predator dies out (i) suffering from a smaller conversion rate for P(0) = 0.128; Q(0) = 0.9; r = 3.002; a = 0.252; K = 25; θ = 0.98; τ = 1.001232; β = 1.03; c = 0.00030. Coexistence of species is restored in (j), when prey assimilation is instantaneous for P(0) = 0.128; Q(0) = 0.89; r = 3.002; a = 2.252; K = 25; θ = 0.98; τ = 0; β = 1.03; c = 0.00030.
