"Maximizing Flow Rates in Multi-Hop Two-Tier IoT Networks with Ambient " by Muchen Jiang, Kwan Wu Chin et al.
This paper considers routing and link scheduling in a two-tier wireless Internet of Things (IoT) network. The first tier consists of routers that communicate via active Radio Frequency (RF) transmissions. The second tier consists of passive tags that backscatter ambient RF signals from routers. Our objective is to maximize the network throughput at both tiers. To this end, we outline a Mixed Integer Linear Program (MILP) that jointly optimizes the active time of RF links and backscatter links, and traffic over links. We also present a heuristic called Algorithm-Transmission-Set-Generator (ALGO...
