Model-based clock synchronization protocol for wireless sensor networks
Nikolaos Freris, Vivek Borkar, P. R. Kumar
In a wireless sensor network, nodes communicate time-stamped packets in order to synchronize their clocks, i.e., estimate each other's time display. We introduce and analyze a para…
The Importance, Design and Implementation of a Middleware for Networked Control Systems
Kyoung-Dae Kim, P. R. Kumar
Due to the advancement of computing and communication technology, networked control systems may soon become prevalent in many control applications. While the capability of employin…
Fundamentals of Large Sensor Networks: Connectivity, Capacity, Clocks and Computation
Nikolaos M. Freris, Hemant Kowshik, P. R. Kumar
Sensor networks potentially feature large numbers of nodes that can sense their environment over time, communicate with each other over a wireless network, and process information.…
Scheduling Heterogeneous Real-Time Traffic over Fading Wireless Channels
I-Hong Hou, P. R. Kumar
We develop a general approach for designing scheduling policies for real-time traffic over wireless channels. We extend prior work, which characterizes a real-time flow by its traf…
Utility Maximization for Delay Constrained QoS in Wireless
I-Hong Hou, P. R. Kumar
This paper studies the problem of utility maximization for clients with delay based QoS requirements in wireless networks. We adopt a model used in a previous work that characteriz…
