Collaborative Scheduling and Synchronization of Distributable Real-Time Threads
(Virginia Tech, 2010-05-05)
In this dissertation, we consider the problem of scheduling and synchronization of distributable real-time threads --- Real-Time CORBA's first-class abstraction for programming real-time, multi-node sequential behaviors. ...
Duty-Cycled Wireless Sensor Networks: Wakeup Scheduling, Routing, and Broadcasting
(Virginia Tech, 2010-04-26)
In order to save energy consumption in idle states, low duty-cycled operation is widely used in Wireless Sensor Networks (WSNs), where each node periodically switches between sleeping mode and awake mode. Although efficient ...
On Reducing Delays in P2P Live Streaming Systems
(Virginia Tech, 2010-09-03)
In the recent decade, peer-to-peer (P2P) technology has greatly enhanced the scalability of multimedia streaming on the Internet by enabling efficient cooperation among end-users. However, existing streaming applications ...
Scheduling Distributed Real-Time Tasks in Unreliable and Untrustworthy Systems
(Virginia Tech, 2010-01-22)
In this dissertation, we consider scheduling distributed soft real-time tasks in unreliable (e.g., those with arbitrary node and network failures) and untrustworthy systems (e.g., those with Byzantine node behaviors). We ...
Energy Efficient Target Tracking in Wireless Sensor Networks: Sleep Scheduling, Particle Filtering, and Constrained Flooding
(Virginia Tech, 2010-12-03)
Energy efficiency is a critical feature of wireless sensor networks (WSNs), because sensor nodes run on batteries that are generally difficult to recharge once deployed. For target tracking---one of the most important WSN ...
