Time-and-Frequency-Hopping Optical Orthogonal Codes with Hierarchical Cross-Correlation Constraints for Service Differentiation
— In this paper, we consider time-and-frequency hopping (TFH) codes for optical code-division multiple-access (OCDMA) networks. To support the differentiated service requirements...

Group Priority Scheduling
We present an end-to-end delay guarantee theorem for a class of guaranteed-deadline (GD) servers. The theorem can be instantiated to obtain end-to-end delay bounds for a variety of...

Distributed bearing estimation via matrix completion
We consider bearing estimation of multiple narrow-band plane waves impinging on an array of sensors. For this problem, bearing estimation algorithms such as minimum variance disto...

Smooth switching problem in buffered crossbar switches
Scalability considerations drive the switch fabric design to evolve from output queueing to input queueing and further to combined input and crosspoint queueing (CICQ). However, f...

Stochastic event capture using mobile sensors subject to a quality metric
Mobile sensors cover more area over a period of time than the same number of stationary sensors. However, the quality of coverage achieved by mobile sensors depends on the velocit...
