Target searching is one of the challenging research areas which finds applications in many critical real-time scenarios. The modeling and analysis play a vital role to solve real-time problems. This paper addresses a number of grid-based target searching problems in a single searcher-single target environment applicable to real-time scenarios and various approaches are introduced for modeling and analyzing the problems. The solutions derived from the proposed approaches facilitate the understanding of the problems in detail. We have initially, modeled and analyzed the problems as an extensive-form game and a normal-form game, by deducing appropriate strategies for the respective players (searcher and target) along with expected payoffs. In the paper, a mobile sensor and a mobile object play the role of a searcher and a target, respectively. Later, the problem is viewed from a different dimension by representing it as a state transition diagram and a finite automaton to highlight the differences resulting from varying activities of the searcher and the target. This is further extended to key-based target searching with an aim to minimize the search time. In this paper, we have highlighted few real-time target searching problems similar to the identified problems in the conclusion.
