In addition, Gupta et al. [9] presented three types of harvesting functions (constant harvesting, proportional harvesting, nonlinear harvesting), and showed that nonlinear harvesting is more realistic than constant harvesting and proportional harvesting.
However, these schemes focused on analyzing the fundamental energy harvesting functions with the network coding and did not consider the specific relationship between the energy harvesting and the optimal stochastic policies in the network coding capable green CR network.
This had some shortcomings; like the fact that the radio module was solely responsible for executing the harvesting function and determining the amount of harvested energy.
Though this nonlinear harvesting function is more realistic, not many researchers have used it in their studies.
(iii) The harvesting function did not account for the handling time of the catch and the competition between standard vessels which are utilized for harvesting of resource.
The present paper is concerned with the dynamics of a discrete-time economic predator prey system in the presence of a type of nonlinear harvesting function.
The model, featuring a more realistic nonlinear harvesting function, will give rise to some interesting dynamic behaviors, as we see in Sect. 4.
Equation (2.1) is a semi-explicit autonomous differential-algebraic equations with differential index 1, (frac{xE}{1+mx}) is the harvesting function with constant m being related to the handling or processing time [17, 19].
Recently, assuming that the harvesting function is a function of the delayed estimate of the true population, Berezansky et al. [3] studied the following Nicholson blowflies model with a linear harvesting term: begin{aligned}& x'(t)=-delta x t)+Px t-tau e^{-gamma x(t-tau)}-Hx(t-sigma),quad delta,p,tau,H,sigma in (0,+Px t-tau e
Specifically, if we consider the energy consumption of the sensor node due to the false positive of the interferences (i.e., WiFi, Bluetooth, and electric-oven signal), the new duty cycling design with the energy harvesting function is necessary for the interferences resilience.
Proteins from the CAC, LHCR and CAB protein families mainly fulfill a light harvesting function, while members of the LHC-like, LI818/LHCX/LHCSR, PSBS and LHL4 families are mainly involved in photoprotection and photoacclimation.
