Model with Cause and Effect for MANET (M-CEM)

Mobile ad-hoc network has gained popularity in recent years. There are several challenges faced by the researchers in this area. The most common research issue is the performance evaluation and enhancement. As we know that the performance of the MANET cannot be evaluated only with the selection of the protocol because the routing performance needs environment to operate. There are many network environmental conditions i.e., causes (e.g. Node mobility, number of nodes, pause time, network size etc.), which influence the performance of MANET. So it needs to emphasize to detect the possible causes (environmental causes) and their effect on performance. In this paper we have focused on this issue by developing a Model with Cause and Effect for MANET (M-CEM). The model has been tested on multiple scenarios and some serious causes and their effects were detected in MANET performance. The model is based on Fuzzy-AHP (Analytical Hierarchy Process) for decision making. Fuzzy Decision Map (FDM) has been used by evaluating weightage of possible causes. The model is simulated under NS2.34 and tested for various imaginary network environmental conditions. The model was found satisfactory to handle uncertainty, vagueness and imprecise information of various possible network causes.
