Cross-Layer Design with Adaptive Modulation: Delay, Rate, and Energy Tradeoffs
— We present a crosslayer framework for optimizing the performance of wireless networks as measured by applications or upper layer protocols. The approach combines adaptive modul...

Deployment algorithms for a power-constrained mobile sensor network
Abstract— This paper presents coverage algorithms for mobile sensor networks in which agents have limited power to move. Rather than making use of a constrained optimization tech...

Cognitive Medium Access: A Protocol for Enhancing Coexistence in WLAN Bands
— In this paper we propose Cognitive Medium Access (CMA), a protocol aimed at improving coexistence with a set of independently evolving WLAN bands. A time-slotted physical layer...

Entropy and Memory Constrained Vector Quantization with Separability Based Feature Selection
An iterative model selection algorithm is proposed. The algorithm seeks relevant features and an optimal number of codewords (or codebook size) as part of the optimization. We use...
