Investigation of Channel Usage and Packetloss in a MANET Testbed for Stairs Indoor 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 analyse our MANET test bed regarding packet loss metric considering the Optimized Link State Routing (OLSR) protocol. We implemented two models. One when all the nodes are static and another one when one node is moving. In this work, we assess the performance of our MANET test bed in terms of packet loss, considering IEEE 802.11 channel usage in the environment. From our experiments, we found that the OLSR protocol has a good performance when nodes are in stationary state. We observed that the number of packet loss increases after 2-hops for static model and after 1-hop for moving model. The channel usage in each floor also influences the results of packet loss.
