近年来，MANET因其在军事活动、救援行动和时间要求苛刻的应用等领域的潜在用途而继续受到人们的关注。在本文中，我们给出了我们实现的MANET测试床的实现和分析，考虑到AODV和OLSR协议的无线多跳网络。我们研究了移动性和拓扑变化对移动自组网的影响。在这项工作中，我们考虑了四种场景：静态、源移动、目标移动和源-目标移动。我们通过吞吐量、丢弃的数据包数和延迟来评估我们的测试床的性能。通过实验发现，在源节点和目的节点都在移动的情况下，OLSR协议比AODV协议具有更好的性能。AODV作为一种反应式协议，在路由快速、连续变化的情况下比OLSR慢。
In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering AODV and OLSR protocols for wireless multi-hop networking. We investigate the effect of mobility and topology changing in MANET. In this work, we consider four scenarios: Static, Source Moving, Destination Moving and Source-Destination Moving. We assess the performance of our testbed in terms of throughput, number of dropped packets and delay. From our experiments, we found that OLSR protocol has a better performance than AODV when both source and destination nodes are moving. AODV as a reactive protocol, is slower than OLSR when routes are changing quickly and continuously.
