The quality of wireless links suffers from time-varying channel degradations such as
interference, flat-fading, and frequency-selective fading. Current radios are limited in their …

Low power consumption is a key design metric for portable wireless network devices where
battery energy is a limited resource. The resultant energy efficient design problem can be …

Wireless network links are characterized by rapidly time varying channel conditions and
battery energy limitations at the wireless mobile user nodes. Therefore static link control …

In this paper, we prove that the problem of maximizing data throughput by adaptive
modulation and power control while meeting packet error requirements is NP-complete. A …

Video transmission over wireless packet networks is gaining importance due to the concept
of universal personal communication. Further, it is considered an important step towards …

Telecom trends such as smooth migration towards higher data rates and higher capacities
for multimedia applications, and provision of various services (text, audio, video) from …

In this paper a novel link adaptation algorithm is proposed that is capable of adjusting the
transmit power level and the data rate jointly to the radio channel conditions. The proposed …

It is well known that link adaptation techniques, when designed to track the channel
variations, yield a higher network throughput. In this work, we investigate the throughput …

In this paper, we introduce a novel approach for adaptive minimization of the total energy
consumption in multimedia wireless communications subject to achieving a given quality of …

We provide a theoretical framework for cross-layer design in multimedia communications to
optimize single-user throughput by selecting the transmitted bit rate and payload size as a …
