1 CSMA Self-Adaptation based on Interference Differentiation

by Jing Zhu, Xingang Guo, Sumit Roy, Konstantina Papagiannaki
"... Abstract—this paper addresses the design challenge of interference mitigation in the emerging high density (HD) wireless LAN. It is proposed to differentiate interference according to their energy and timing relative to desired signal, and measure packet error rate (PER) locally at transmitter for e ..."

for each type of interference. Then, self-adaptation algorithms are designed to adjust a) clear channel assessment (CCA) threshold, aka physical carrier sensing threshold, to leverage spatial reuse for achieving higher aggregate throughput, and b) transmit power (TP) to compensate location difference among

Integrating non-interfering versions of programs

by Susan Horwitz, Jan Prins, Thomas Reps - ACM Transactions on Programming Languages and Systems , 1989
"... The need to integrate several versions of a program into a common one arises frequently, but it is a tedious and time consuming task to integrate programs by hand. To date, the only available tools for assisting with program integration are variants of text-based differential file comparators; these ..."

A Multichannel CSMA MAC Protocol with Receiver-Based Channel Selection for Multihop Wireless Networks

by Nitin Jain, Samir R. Das, Asis Nasipuri - In IEEE IC3N , 2001
"... In this paper, we propose a CSMA-based medium access control protocol for multihop wireless networks that uses multiple channels and a dynamic channel selection method. The proposed protocol uses one control channel and # data channels, where # is independent of the number of nodes in the network ..."

RegionDCF: a Self-Adapting CSMA/Round-Robin Media Access Protocol for WLAN

by Alberto Riggi, Javier Gomez
"... Abstract—This paper presents RegionDCF, a self-adapting media access control protocol for WLAN that seamlessly behaves as CSMA or round-robin access techniques taking advantage of the most effective properties of each access method. In contrast to preceding works in this area that focused on enhance ..."

Multichannel CSMA with Signal Power-Based Channel Selection for Multihop Wireless Networks

by Asis Nasipuri - in IEEE Vehicular Technology Conference , 2000
"... We describe a new carrier–sense multiple access (CSMA) protocol for multihop wireless networks, using multiple channels and a distributed channel selection scheme. The proposed protocol divides the available bandwidth intoÆchannels where the transmitting station selects an appropriate channel for pa ..."

for packet transmission. The selection criterion is based on the interference power measurements on the channels. We show via simulations that this multichannel CSMA protocol provides a higher throughput compared to its single channel counterpart by reducing the packet loss due to collisions. 1

Modeling hippocampal and neocortical contributions to recognition memory: A complementary-learning-systems approach

by Kenneth A. Norman, Randall C. O’Reilly - PSYCHOLOGICAL REVIEW , 2003
"... We present a computational neural network model of recognition memory based on the biological structures of the hippocampus and medial temporal lobe cortex (MTLC), which perform complementary learning functions. The hippocampal component of the model contributes to recognition by recalling specific ..."

We also use the model to address the stochastic relationship between recall and familiarity (i.e., are they independent), and the effects of partial vs. complete

Achievable rate region of CSMA schedulers in wireless networks with primary interference constraints

by Peter Marbach, Atilla Eryilmaz, Asuman Ozdaglar - in Proc. IEEE Conf. Decis. Control
"... (CSMA) schedulers for wireless networks. For networks where all nodes are within transmission range of each other, it has been shown that such schedulers achieve the network capacity in the limiting region of large networks with a small sensing delay. However the design and analysis of CSMA schedule ..."
Abstract - Cited by 24 (8 self) - Add to MetaCart
schedulers for general networks has been an open problem due to the complexity of the interaction among coupled interference con-straints. For networks with primary interference constraints, we introduce a tractable analysis of such CSMA schedulers based on a fixed point approximation. We then use

Differential evolution algorithm with strategy adaptation for global numerical optimization

Abstract—Differential evolution (DE) is an efficient and powerful population-based stochastic search technique for solving optimiza-tion problems over continuous space, which has been widely applied in many scientific and engineering fields. However, the success of DE in solving a specific problem c ..."
