Dynamic Control of Data Ferries under Partial Observations

Abstract: Abstract-Controlled mobile helper nodes called data ferries have recently been proposed to bridge communications between disconnected nodes in a delay-tolerant manner. While existing work has explored various trajectory designs for the data ferry by assuming either static nodes or full observations at the data ferry, the problem remains open when the nodes are mobile and the ferry only has partial observations. In this paper, we investigate the problem of dynamic ferry mobility control under limitedrange sensi… Show more

“…The dynamic advertising problem can be considered as a Markov Decision Process (MDP) [28] [29], which is a common model of reinforcement learning. Briefly speaking, in markov decision process, an agent will repeatedly observe the current state s t of the environment and take an action a from all available actions in this state.…”

“…• Ferry trajectory and mobility: Unlike some previously studied applications of message ferrying [7], there is absolutely no control over the trajectory and mobility of the ferries. Cars can suddenly leave the road to the switching centre or get stuck in an unexpected traffic jam causing serious disruptions to end-to-end QoS.…”

“…Over the last decade, researchers have studied message ferrying or delay tolerant networking (DTN) for a diverse range of applications, including e-mail delivery to disconnected villages [11], restoring connectivity between partitioned mobile nodes [16,7], collecting data from a sensor network [6], and providing roadside-to-roadside (r2r) [8] data transfer service using vehicles as mobile ferries. Among them, r2r is the closest to the proposed ferry-based cellular backhaul service considered in this paper.…”

“…Instead, the ferry route is computed from the locations of the clusters. Existing works such as [16], [10], [13], [8], [11] have been proposed for such a scenario, as shown in Fig. 1b.…”
