The propagation of small amplitude dust ion acoustic (DIA) solitary waves (SW) in four component relativistic plasma with nonthermal electrons, mobile positively charged ions and positrons, and negatively charged massive dust particles is discussed in this paper. The Korteweg-de-Vries (K-dV) nonlinear wave equation is numerically derived using the reductive perturbation approach. The role of streaming positron beam on the characteristic features of solitary waves are observed and the possible region of the formation of ion acoustic (IA) SW is analysed. The findings of this work will help in the understanding of the Earth's upper atmosphere (Ionosphere's Aurora region) as well as the space plasmas. [ABSTRACT FROM AUTHOR]
