TLDR
For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells, and the authors demonstrate exponentially fast convergence to these settings whenever power settings exist for which all users meet the rho requirement.Abstract:
For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signal-to-interference ratio of rho per user, channel reuse is maximized. Distributed procedures for doing this are of special interest, since the centrally administered alternative requires added infrastructure, latency, and network vulnerability. Successful distributed powering entails guiding the evolution of the transmitted power level of each of the signals, using only focal measurements, so that eventually all users meet the rho requirement. The local per channel power measurements include that of the intended signal as well as the undesired interference from other users (plus receiver noise). For a certain simple distributed type of algorithm, whenever power settings exist for which all users meet the rho requirement, the authors demonstrate exponentially fast convergence to these settings. >read more

Power Control for Interference Management and QoS Guarantee in Heterogeneous Networks
TL;DR: This work transforms the original nonconvex problem into a convex problem and develops a distributed algorithm that can attain the global optimal transmit power values, which has heavy network overheads, which may lead to increased energy consumption for femtocell user equipment.

New media access protocols for wireless ad hoc networks based on cross-layer principles
Stavros Toumpis,Andrea Goldsmith +1 more
TL;DR: Two new medium access control protocols for wireless ad hoc networks, the progressive backoff algorithm (PBOA) and the progressive ramp up algorithm (PRUA) are introduced and it is shown that both protocols perform better than CSMA/CA and PCM in terms of throughput and robustness with respect to the choice of the routing protocol.

Energy-Saving Resource Management for D2D and Cellular Coexisting Networks Enhanced by Hybrid Multiple Access Technologies
TL;DR: This paper proposes a unified resource management scheme to minimize the total transmit power of all MDs by jointly optimizing mode selection, resource allocation, and power control and analytically gets the optimal resource-sharing mode for cellular users and D2D users based on the mapping rule between SCMA codebooks and OFDMA resource blocks.

Adaptive power control of cellular CDMA systems via the optimal predictive model
TL;DR: A predictive adaptive power control scheme is proposed to compensate for the time delay and reduce the affects of channel fading and interference, thus achieving optimal tracking, in the sense of minimum mean square error control error, of the desired signal-to-interference-plus-noise ratio.
