Tournament MAC with Constant Size Congestion Window for WLAN
نویسنده
چکیده
In the context of radio distributed networks, we present a generalized approach for the Medium Access Control (MAC) with fixed congestion window. Our protocol is quite simple to analyze and can be used in a lot of different situations. We give mathematical evidence showing that our performance is tight, in the sense that no protocol with fixed congestion window can do better. We also place ourselves in the WiFi/WiMAX framework, and show experimental results enlightening collision reduction of 14% to 21% compared to the best known other methods. We show channel capacity improvement, and fairness considerations.

Notre protocole est simple à analyser et peut-être utilisé dans beaucoup de contextes différents. Nous donnons des argument mathématiques pour prouver que la performance du protocol est optimale, dans le sens où aucun protocole avec fenètre de congestion fixe ne peut l’améliorer. Nous nous plaçons aussi dans le contexte WiFi/WiMAX, et nous montrons expérimentalement une réduction du taux de collision entre 14% et 21% par rapport aux meilleures méthodes connues. Nous montrons aussi l’amélioration obtenue en capacié de canal, et analysons les questions d’équité pour ce protocole.

Resolving Performance Anomaly Using ARF-Aware TCP
In this study, we propose ARF-aware TCP that resolves the performance anomaly in 802.11 WLAN networks. Performance anomaly is a network symptom that fairness among the nodes is broken when multiple nodes in the same channel have different link rates. Recent studies on the performance anomaly focus on QoS mechanism at MAC layer. However, MAC layer approach has drawbacks such as framing overhead ...
متن کاملThroughput and QoS Optimization in IEEE 802.11 WLAN
In a wireless LAN (WLAN) based on IEEE 802.11, supporting multiple classes of services with QoS constraints in MAC layer is very important. In this paper, we propose a class-based analytical model to support multiple traffic classes. Through investigating the relationship between access control parameters, such as contention window (CW) sizes and inter-frame space (IFS) under QoS constraints, w...
متن کاملCongestion Avoidance based on RC-MAC Protocol in Wireless Sensor Networks
Application for wireless sensor network is notably different in its characteristics and requirement from a standard WLAN. When a critical event triggers a surge of data generated by the sensor, congestion may occur as data packet converge toward a sink, which causes energy waste, throughput reduction, information loss, hidden terminal problem and link failure in contention based MAC protocol. D...
متن کاملPerformance study of MAC for service differentiation in IEEE 802.11
In a wireless local area network (WLAN), Medium access control (MAC) layer access parameters are usually differentiated for various classes of users to provide different Quality of Service (QoS). In particular, in this paper, we will investigate the MAC layer performance of IEEE 802.11e based WLAN, where the traffic flows are classified and each class is assigned different MAC parameters, such ...
متن کاملReliable on-demand multicast routing with congestion control in wireless ad hoc networks
In this paper, we address the congestion control multicast routing problem in wireless ad hoc networks through the medium access control (MAC) layer. We first introduce the Broadcast Medium Window (BMW) MAC protocol, which provides reliable delivery to broadcast packets at the MAC layer. We then extend the wireless On-Demand Multicast Routing Protocol (ODMRP) to facilitate congestion control in...
