Performance Analysis of the IEEE 802.11 Distributed Coordination Function
, 2000
"... Recently, the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slott ..."

employed by DCF, namely, the basic access and the RTS/CTS access mechanisms. In addition, it also applies to a combination of the two schemes, in which packets longer than a given threshold are transmitted according to the RTS/CTS mechanism. By means of the proposed model, in this paper we provide
A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks
, 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

the WaveLAN II [15]. We show that RBAR is better because it results in a more efficient channel quality estimation which is then reected in a higher overall throughput Our protocol is based on the RTS/CTS mechanism and consequently it can be incorporated into many medium access control protocols including
Robust rate adaptation for 802.11 wireless networks
- in ACM Mobicom
, 2006
"... Rate adaptation is a mechanism unspecified by the 802.11 standards, yet critical to the system performance by exploiting the multi-rate capability at the physical layer. In this paper, we conduct a systematic and experimental study on rate adaptation over 802.11 wireless networks. Our main contribut ..."

The Impact of RTS Threshold on IEEE
"... Wireless technologies and applications received great at-tention in recent years. The medium access control (MAC) protocol is the main element that determines the efficiency in sharing the limited communication bandwidth of the wireless channel in wireless local area networks (WLANs). The request-to ..."

-to-send/clear-to-send (RTS/CTS) mechanism is an optional handshaking procedure used by the IEEE 802.11 wireless network to reduce the possibility of col-lision. The RTS Threshold (RT) value which determines when the RTS/CTS handshaking mechanism should be used is an important parameter to investigate; since different RT
Local Search with Memory: Benchmarking RTS
, 1994
"... this paper is dedicated to benchmarking RTS, we completely describe the algorithm but omit the detailed analysis given in the cited papers because it is not necessary for the scope of this work. The Tabu Search technique (TS) represents a meta-strategy that permits to complement a local search heuri ..."

RTS/CTS-Induced Congestion in Ad Hoc Wireless LANs
, 2003
"... The RTS/CTS mechanism is widely used in wireless networks in order to avoid packet collisions and, thus, achieve high throughput. In ad hoc networks, however, the current implementation of the RTS/CTS mechanism may lead to interdependencies so that nodes become unable to transmit any packets during ..."

Phase-dependent Evaluation in RTS Games
"... Modern video games present an environment in which game AI is expected to behave realistically (i.e., ‘human-like’). One feature of human-like behaviour of game AI, is the ability to assess accurately the current situation. This requires an appropriate evaluation function. The high complexity of mod ..."

, and discusses the experiments performed in the real-time strategy (RTS) game SPRING. Two evaluation terms are established, one to perform a unit-based evaluation, the other to evaluate positional safety. In addition, a mechanism is incorporated to perform the evaluation dependent on the phase of the game. From
Computationally Efficient Scheduling with the Physical Interference Model for Throughput Improvement in Wireless Mesh Networks

"... Wireless mesh networks are expected to be widely used to provide Internet access in the near future. In order to fulfill the expectations, these networks should provide high throughput simultaneously to many users.

In this paper, we investigate throughput improvements achievable by replacing CSMA/CA with an STDMA scheme where transmissions are scheduled according to the physical interference model. To this end, we present a computationally
