YSF: a 6TiSCH Scheduling Function Minimizing Latency of Data Gathering in IIoT

‏‎interpersonal function of language in subtitling

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

Minimizing Average Flow Time in Sensor Data Gathering

Building on previous work [Bonifaci et al., Minimizing flow time in the wireless gathering problem, STACS 2008] we study data gathering in a wireless network through multi-hop communication with the objective to minimize the average flow time of a data packet. We show that for any ∈ (0, 1) the problem is NP-hard to approximate within a factor better than Ω(m1− ), where m is the number of data p...

Understanding optimal data gathering in the energy and latency domains of a wireless sensor network

The problem of optimal data gathering in wireless sensor networks (WSNs) is addressed by means of optimization techniques. The goal of this work is to lay the foundations to develop algorithms and techniques that minimize the data gathering latency and at the same time balance the energy consumption among the nodes, so as to maximize the network lifetime. Following an incremental-complexity app...

A Value-driven System for Scheduling Information Gathering a Value-driven System for Scheduling Information Gathering

This paper presents a system for scheduling information gathering in an information rich domain under time and monetary resource restrictions. The system gathers information using an explicit representation of the user's decision model and a database of information sources. Information gathering actions (queries) are scheduled myopically by selecting the query with the highest marginal value. T...
