Experimental Evaluation of a MANET Testbed in Indoor Stairs Scenarios

In recent years, Mobile Ad hoc Networks (MANETs) are continuing to attract the attention for their potential use in several fields. Mobility and the absence of any fixed infrastructure make MANETs very attractive for mobility and rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering the Optimized Link State Routing (OLSR) protocol. We consider two models. One when all the nodes are static and another one when one node is moving. The mobile node moves toward the destination at a regular speed and when arrives at the corner of stairs is stops for about three seconds. In this work, we assess the performance of our MANET testbed in terms of throughput and packet loss. From our experiments, we found that the OLSR protocol has a good performance when nodes are in stationary state. However, when the node moves the throughput is decreased. We observed that the number of packet loss increases after 2-hops for static model and after 1-hop for moving model. But, when the node is moving, the packet loss for 2-hops to 4-hops is almost the same.
