Real-Time Scheduling for WirelessHART Networks

by Abusayeed Saifullah, You Xu, Chenyang Lu, Yixin Chen
"... WirelessHART is an open wireless sensor-actuator network standard for industrial process monitoring and control that requires real-time data communication between sensor and actuator devices. Salient features of a WirelessHART network include a centralized network management architecture, multi-chan ..."

-channel TDMA transmission, redundant routes, and avoidance of spatial reuse of channels for enhanced reliability and real-time performance. This paper makes several key contributions to real-time transmission scheduling in WirelessHART networks: (1) formulation of the end-to-end real-time transmission

Adaptive Scheduling for Multicasting Hard Deadline Constrained Prioritized Data via Network Coding

by Tuan T. Tran, Hongxiang Li, Lingjia Liu, Samee U. Khan
"... Abstract—Network coding offers a promising platform for multicast transmission by approaching its min-cut capacity. However, pushing the network throughput toward this upper bound comes with a sacrifice in delivery delay due to the decoding procedure that requires performing batch of coded packets. ..."

due to the limited delivery time and data interdependencies. In this paper, we consider single-hop wireless networks where the transmitter wishes to multicast hard deadline constrained prioritized data to many receivers over lossy channels. We first study the network performance of a variety

Energy-Efficient Flow Scheduling and Routing with Hard Deadlines in Data Center Networks

by unknown authors
"... Abstract—The power consumption of enormous network de-vices in data centers has emerged as a big concern to data center operators. Despite many traffic-engineering-based solutions, very little attention has been paid on performance-guaranteed energy saving schemes. In this paper, we propose a novel ..."
Abstract - Add to MetaCart
energy-saving model for data center networks by scheduling and routing “deadline-constrained flows ” where the transmission of every flow has to be accomplished before a rigorous deadline, being the most critical requirement in production data center networks. Based on speed scaling and power-down energy

Near Optimal Rate Selection for Wireless Control Systems

by Abusayeed Saifullah, Chengjie Wu, Paras Babu Tiwari, You Xu, Yong Fu, Chenyang Lu, Yixin Chen
"... Abstract—With the advent of industrial standards such as WirelessHART, process industries are now gravitating towards wireless control systems. Due to limited bandwidth in a wireless network shared by multiple control loops, it is critical to optimize the overall control performance. In this paper, ..."
Abstract - Cited by 22 (15 self) - Add to MetaCart
, we address the scheduling-control co-design problem of determining the optimal sampling rates of feedback control loops sharing a WirelessHART network. The objective is to minimize the overall control cost while ensuring that all data flows meet their end-toend deadlines. The resulting constrained

Algorithms for some Non-convex Resource Optimizations in Wireless Sensor Networks: Energy Efficient Scheduling and Collaborative Relaying

by Rajgopal Kannan
"... as constrained optimizations (maximization or minimization problems). However the constraints/objective function(s) need not be convex/concave. In this case, traditional analytical techniques do not work. We are therefore interested in developing algorithmic approximations. Formulations and Research ..."

and Research Issues: We illustrate via the following two examples: energyefficient scheduling and collaborative relaying. • Energy-efficient scheduling: Energy-efficiency is a critical concern in wireless sensor networks; network lifetime and utility are dependent on the design of energy

A Real-Time Control Network Protocol for Embedded Systems Using Controller Area Network

by Paul Richardson, Peter Haniak, Peter Haniak, Larry Sieh, U. S. Army, Vetronics Tank-automotive - CAN)”, IEEE Electronic and Information Technology Conference , 2001
"... Controller Area Network (CAN) is a priority driven network protocol that can be found in a wide range of embedded systems (e.g.: automotive, military, aerospace, manufacturing,...). The networks in these applications are inherently real-time local area networks (LANs) whose correct performance is sp ..."

Per has in a seemingly easy way spotted erroneous assumptions, has valued my research contributions, and has connected my own work with another broader world of research. I want to thank all colleagues in the Networked
