In this paper, we investigate the dynamics of a discrete-time predator-prey system involving group defense.The existence and local Dugout stability of positive fixed point of the discrete dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by usi
There is a growing interest in the use of Autonomous Underwater Vehicles (AUVs) and Underwater Sensor Networks Odor Absorber (USNs) for scientific, military, and industrial applications, leading to the development of wireless underwater communications.However, the channel for Underwater Acoustic (UWA) communications is challenging compared to the r
