Distributed Medium Access Control with SDMA Support for WLANs
SUMMARY With simultaneous multiuser transmissions, spatial division multiple access (SDMA) provides substantial throughput gain over the single user transmission. However, its implementation in WLANs with contention-based IEEE 802.11 MAC remains challenging. Problems such as coordinating and synchronizing the multiple users need to be solved in a distributed way. In this paper, we propose a dis...
متن کاملA Differentiated Service Model for Enhanced Distributed Channel Access (EDCA) of IEEE 802.11e WLANs
In this paper, we propose a new differentiated service model, referred to as Differentiated Service-EDCA (DS-EDCA), for the Enhanced Distributed Channel Access (EDCA) of IEEE 802.11e wireless local area networks (WLANs). With DS-EDCA, both strict priority and weighted fair service can be provided. The strict priority service is provided for high priority traffic through carefully setting the ED...
متن کاملOFDMA-Based Medium Access Control for Next-Generation WLANs
Existing medium access control (MAC) schemes for wireless local area networks (WLANs) have been shown to lack scalability in crowded networks and can suffer from widely varying delays rendering them unsuited to delay sensitive applications, such as voice and video communications. These deficiencies are mainly due to the use of random multiple access techniques in the MAC layer. The design of th...
متن کاملDistributed Fair Auto Rate Medium Access Control for IEEE 802.11 Based WLANs
∗ Much research has shown that a carefully designed auto rate medium access control can utilize the underlying physical multi-rate capability to exploit the time-variation of channel. In this paper, we develop a simple analytical model to investigate the rule maximizing the throughput of RTS/CTS based multi-rate wireless local area networks. Based on the obtained rule, we propose two distribute...
متن کاملCall Admission Control in IEEE 802.11e EDCA-based WLANs
The random access MAC protocol of WLANs is a key aspect in the actual rapid deployment of WLANs. However, the lack of a hard centralized control of the transmission resources, complicating an efficient implementation of QoS mechanisms without losing the inherent advantages of the distributed access scheme. To solve this difficulties, the EDCA IEEE 802.11e proposal has been released but, critica...
