Abstract:

Several researches on reliability studies of ad hoc network, assumed that the communication links between any two mobile nodes exist if the Euclidean distance between them is not greater than the transmission range of the nodes. These methods are purely distance-dependent models and the randomness in the signal strength in radio communication is not taken care-off. This way of modeling the channel for reliability studies may be intuitively a valid theoretical study. However, the wireless channel can be modeled in a more realistic manner by considering the randomness caused due to shadowing effects. In this paper, we characterize the connectivity of the MANET in a log–normal shadow fading environment. The simulated results are of practical significance for the design of MANET and offers insights into how the channel randomness has been considered for the MANET reliability evaluation through Monte Carlo Simulation approach to depict the impact of shadowing deviation.
