移动的Ad Hoc网络（MANET）是一种动态的网络，由于其无线特性，可以部署为多跳分组网络。它是一个无线网络，并具有动态拓扑结构，由于其节点的移动性。网络的应用越来越广泛，用户的需求促使了异构移动自组网的出现。相对于同构型移动自组网，异构型移动自组网对其他类型的网络（如无线局域网、蜂窝网络和固定网络）具有更大的开放性。在移动自组网中，更多的是关注配置，而配置中的一个重要元素就是路由。按需距离矢量（AODV）协议是一种能够很好地融合移动自组网特性的路由协议。本研究的目的是通过仿真的方法来评估AODV协议在同构和异构移动自组网中不同移动速度下的性能。来自HetMAN架构（如在以前的工作中讨论）的仿真场景已经在OMNeT++网络模拟器中开发。从测试中取得的结果进行了评估，使用的指标分配;吞吐量和数据包传输率（PDR）。测试结果表明，随着速度的增加，吞吐量和PDR降低同构和异构的MANET。从测试中我们也可以得出结论，在同构移动自组网的性能优于异构移动自组网。
Mobile Ad Hoc Network (MANET) is a dynamic network without fixed infrastructure due to their wireless nature and can be deployed as multi-hop packet networks. It is a wireless network and has dynamic topology due to its node mobility. Networks are being used in various areas and the demand of users nowadays has motivated the emergence of the heterogeneous MANET. Compared to homogeneous MANET, heterogeneous MANET is more open to other types of network for example wireless LAN, cellular network and fixed network. In MANET, the concern is more to configuration and one of the important elements in configuration is routing. Ad hoc On Demand Distance Vector (AODV) is one of the routing protocols in MANET which can compromise with MANET characteristics. The aim of this research is to assess the performance of AODV in different mobility speed for homogeneous MANET and heterogeneous MANET through the simulation method. The simulation scenarios derived from the HetMAN architecture (as been discussed in previous work) have been developed in the OMNeT++ network simulator. The results achieved from the test have been evaluated using the metrics assigned; throughput and packet delivery ratio (PDR). The tests show that, as the speed increase, the throughput and PDR decrease for both homogeneous and heterogeneous MANET. From the test also, we can conclude that the performance in homogeneous MANET is better than in heterogeneous MANET.
