Description
After a disaster it is important to repair communication networks as fast as possible to save lives. The survivors can use commodity 802.11 WiFi devices to create a wireless multi-hop network to reestablish communication. The distance between neighboring devices is an important parameter to determine the performance of the multi-hop network. In this paper, we determine the effect of the hop distance on the latency and the data rate of the resulting network. We use analytical descriptions of signal propagation and data rate to determine the end-to-end performance of the resulting network. We determine the optimal distance for minimal latency and maximal data rate and show that the two optimization goals result in different hop distances. While the resulting optimal values depend on the scenario parameters, optimizing a network for low latency or high data rate will lead to different placements of relays.
