| Abstract | The mobile ad hoc networks (MANETs) are rapidly deployed in many areas such as disaster area, hospital, conferencing, battle fields, the areas in which the cable networks are not easy to set up, etc. In MANETs, there are different devices such as PDAs, laptops and phones used to transfer the data within the net works. Because of using different devices, the transmission range for each node may not be same. There are two kinds of networks in MANETs: Homogeneous Network in which the nodes use the same transmission range to communicate each other and Heterogeneous Network in which the mobile nodes use the different transmission ranges. There are several different ad hoc routing protocols for controlling the routing in the mobile environment. One of the reactive routing protocols, AODV, is studied in our research to figure out the behavior and performance of AODV in MANETs. We use the network simulator (NS-2) to measure the performance of both homogeneous network and heterogeneous network by using three metrics: varying number of mobile nodes, varying mobile speeds and varying pause times. By using these three metrics, we evaluate the performance of average packet delivery ratio, average throughput, average end to end delay and control overhead. According to the simulation results, the homogeneous network with 250 m transmission range gives the highest average packet delivery ratio, highest throughput, low end to end delay and low control overhead compared with other homogeneous networks and heterogeneous network because the network with larger transmission range can get the good connectivity within the network. From the aspect of the traffic load, the network with high traffic loads lead to degrade the network performance significantly even though large transmission ranges are used |
