Through real-world measurements we evaluate the impact of multihop-aware cooperative relaying on end-to-end route performance in wireless multi-hop networks. In an experiment with 50 devices in an industrial environment cooperative relaying increases the end-to-end transmission reliability for multi-hop links to nearly 100% while reducing the average packet delay. We suggest how to include relay selection...
An emergency node-combined wireless network that uses balloons, electric vehicles, and unmanned aerial vehicles (UAVs) was proposed. We discuss the construction and specific issues of this network. The communication area is evaluated by changing the node elevation. In this network, the elevations of balloon and UAV nodes vary, and the communication area changes with elevation. In addition, the network...
Coding has traditionally been used at the physical layer in communication networks to prevent and correct errors and erasures incurred in transmission of data. In the past decade, other benefits of coding have been demonstrated, in particular in environments with unpredictable dynamics and limited resources. In this paper, we are concerned with using coding to reduce delay in communications environments...
