IA-MAC: Interference Aware MAC for WLANs
نویسندگان
چکیده
Among the numerous standards for wireless communications, the IEEE 802.11 Wireless Local Area Network is the one with the highest utilization at the moment. The 802.11 has been devised explicitly for low mobility, single access point scenario, so its effectiveness can be limited when it is utilized both in ad hoc mode and with multiple access points. Many research has been done and is still ongoing aiming to face well known problems typical of these scenarios like the exposed/hidden terminal cases. In this technical report we propose a novel MAC layer for Wireless LAN which is able to extend the capabilities of the basic IEEE 802.11 DCF (Distributed Coordination Function) to environments with high interference, both in ad hoc and in infrastructured mode.

متن کاملHow to outperform IEEE802.11: Interference Aware (IA) MAC
Wireless networks are nowadays very popular. They are mostly based on IEEE802.11 protocol which is known to show low performance in ad hoc networks. Also when infastructured networks (many access points are placed) are considered, a single transmission could block many radio cells. In this work, we propose Interference Aware (IA) MAC, a modified version of standard IEEE802.11. The main idea is ...
متن کاملA multichannel relay MAC protocol for IEEE 802.11 wireless LANs
One of the challenging issues in wireless LANs (WLANs) is improving the network throughput. One of the possible solutions for the issue is maximizing the number of concurrent transmissions. Although some protocols have been proposed to exploit transmission concurrency in WLANs, their performance depends on the degree of the interference among links. Also, it is hard to obtain interference infor...

To realize the multi-user multiple input multiple output (MIMO) advantage over WLANs, it requires significant changes in the MAC protocol. Either the dominant MAC protocol carrier sense multiple access/collision avoidance (CSMA/CA) needs to be replaced by a novel multi-user MIMO aware MAC protocol or it should be upgraded into multi-user MIMO aware CSMA/CA. Nevertheless, the simplest approach w...
