Moreover, it requires full connectivity of APs which is not necessarily satisfied. In OpenTDMF, we choose to perform time synchronization on backhaul network to avoid above problems. However, it is still non-trivial because we need to handle the delay variance on Ethernet and in AP's ...

1.1. Contributions We claim that user-interactive area coverage and inspection applications relying on UAVs, without the support of a pre-installed networking infrastructure, need a communication backbone properly setup to achieve reliability, a long range, high throughput, and low latency. These ...
While such power efficiency and reliability has been addressed by medium access control (MAC) layer protocols in stationary wireless networking stacks, these energy efficient MAC layers have until now not been extended to include mobile nodes. Since line-of-sight communication can not be assumed, ...
1.2. Approach Most IoT monitoring applications have data to report which are sparse in time and infrequent such as temperature and humidity with low-throughput requirements. This work targets such applications where the gateway has full control over the network for data collection and node ...
