Exploiting Regional Differences: A Spatially Adaptive Random Access [PDF]
, 2015 In this paper, we discuss the potential for improvement of the simple random access scheme by utilizing local information such as the received signal-to-interference-plus-noise-ratio (SINR).

Optimal SINR-based Random Access [PDF]
2010 Proceedings IEEE INFOCOM, 2010 Random access protocols, such as Aloha, are commonly modeled in wireless ad-hoc networks by using the protocol model. However, it is well-known that the protocol model is not accurate and particularly it cannot account for aggregate interference from multiple interference sources.

Modeling and Analysis of K-Tier Downlink Heterogeneous Cellular Networks [PDF]
, 2011 Cellular networks are in a major transition from a carefully planned set of large tower-mounted base-stations (BSs) to an irregular deployment of heterogeneous infrastructure elements that often additionally includes micro, pico, and femtocells, as well ...

The sinR ortholog PGN_0088 encodes a transcriptional regulator that inhibits polysaccharide synthesis in Porphyromonas gingivalis ATCC 33277 biofilms. [PDF]
PLoS ONE, 2013 Biofilm-forming cells are distinct from well characterized planktonic cells and aggregate in the extracellular matrix, the so-called extracellular polymeric substances (EPS).

Proceedings of the 8th ACM international symposium on Mobile ad hoc networking and computing, 2007 In this paper we study the problem of scheduling wireless links in the geometric SINR model, which explicitly uses the fact that nodes are distributed in the Euclidean plane. We present the first NP-completeness proofs in such a model. In particular, we prove two problems to be NP-complete: Scheduling and One-Shot Scheduling. The first problem consists

Effects of practical impairments on cooperative distributed antennas combined with fractional frequency reuse [PDF]
, 2012 Cooperative Multiple Point (CoMP) transmission aided Distributed Antenna Systems (DAS) are proposed for increasing the received Signal-to-Interference-plus-Noise-Ratio (SINR) in the cell-edge area of a cellular system employing Fractional Frequency Reuse

Resolving SINR Queries in a Dynamic Setting [PDF]
SIAM Journal on Computing, 2020 We consider a set of transmitters broadcasting simultaneously on the same frequency under the SINR model. Transmission power may vary from one transmitter to another, and a transmitter's signal strength at a given point is modeled by the transmitter's power divided by some constant power $ $ of the distance it traveled.

Scheduling Policies in Time and Frequency Domains for LTE Downlink Channel: A Performance Comparison [PDF]
, 2017 A key feature of the Long-Term Evolution (LTE) system is that the packet scheduler can make use of the channel quality information (CQI), which is periodically reported by user equipment either in an aggregate form for the whole downlink channel or ...
