摘要：Simulation techniques are being the most important tool that can be used in verification, test and implementation of the Mobile Ad-hoc Network (MANET) environments. These computerized techniques can be feasibly used as a virtual tool to model and operate any suggested environment. MANET was defined “as a set of mobile nodes that moved freely and connected among each other without any infrastructure”. Simulation represents a good reliable tool that can be used to evaluate the performance of an existing or proposed MANET environment under different configurations along periods of real time. In this paper certain MANET’s environment was simulated and operated with AOMDV routing Protocol. The effects of the number of nodes, their speeds and their pause times were modeled and analyzed. The network simulator NS-2 was used as a tool to study and evaluate the effects of these factors. Many performance metrics such as throughput, packets loss, packet delivery fraction (PDF), average end-to-end delay, normalize routing load (NRL) and jitter were used as comparison indications. The simulation environment was implemented with different number of nodes, different speeds, and varying pause times. Significant effects and relations between all these parameters and performance metrics were found and calculated.
