The mobility models are used to represent the unpredictable movement pattern of the nodes in Mobile Ad-


hoc Network (MANET) and give us an idea regarding their location, velocity and acceleration change


over time. These models are used for simulation purpose in standard software tools such as QualNet, ns-2


etc. This paper evaluates the performance of routing protocols for mobility models such as Random Way


Point (RWP), Random Walk (RW) and Random Direction (RD) in presence of obstacles like mountain


which restricts node movement as well obstruct transmission path between nodes based on a parameter


termed as Probability of Reachability (POR). The POR is defined as the fraction of reachable routes to


all possible routes between all pairs of sources and destinations. For this purpose a simulator is designed


in MATLAB. We observe a marked difference in value of POR in presence of obstacles as well as


variation in number of obstacles.
