  We have studied the Rogue wave existence and propagation in Ion-acoustic mode
for the highly energetic case using kappa distributed electrons in accordance
with the Korteweg de Vries equation that is modified KdV and extended KdV
equation. We have used reductive perturbation method. We first examined the
linear dispersive behaviour in Ionacoustic mode. Obtaining the Nonlinear
Schrodinger equation, we simulated Rogue wave and examined dynamics of it, and
its response to small perturbations. We discussed the possibility of generation
of Rogue wave as well as the stability of this against various parameters like
wave number, spatial and time component. This study is quite helpful for
understanding some prominent points of the nonlinearity of IA waves and Rogue
wave generation of the highly energetic case in space plasma also in a
laboratory plasma.
