Mobile ad hoc networks includes self-sustaining mobile nodes that are self-making with no predefined foundation and buildup associations amongst themselves to develop exceptionally powerful topologies due to the nodes mobility in the network. Therefore, due to mobility of the nodes the wireless links may establish (disestablish) implying that the probability of successful communication increases (decreases). Most of the researchers have observed the network performance using binary model of communication links based on Euclidean distance between nodes and the radio range of the mobile nodes i.e., a free space model or line of sight model. In general, signal can reach the destination through different paths and in such cases the signal strength decreases between nodes due to various atmospheric effects such as noise, fading or interference as the distance increases. In this paper, the proposed methodology uses the free space two ray ground propagation model to determine the connectivity of the network during mission time, which helps in determining the network performance (average hop count and path reliability) of the network through simulations in MATLAB. The obtained results shows that the reliability of a homogeneous mobile ad hoc network reduces because of propagation of the signals. Though the reliability values are less, the network is still reliable and it gives an idea for the user to deploy the mobile ad hoc network in a suitable terrains.
