“…The objective of this proposed scheme is to allow transmitting multiple packets at a higher data rate under different conditions of the wireless channel overlapped in time. The proposed scheme presents the performance improvements in aggregate network throughput compared with the existing scheme described in [6]. Thus, the assumptions of this approach are valid for a longer period of time.…”

“…On the other hand, Duchene [6] has made significant modifications to 802.11 MAC protocol to make it more suitable for sending simultaneous transmissions through the wireless channel. Modifications to the 802.11 frame feature of the Distributed Coordination Function (DCFs), the exchange timer, and the weighted gain were discussed.…”

“…Modifications to the 802.11 frame feature of the Distributed Coordination Function (DCFs), the exchange timer, and the weighted gain were discussed. The Media Access (MA)-Aware protocol was proposed in [6] to allow wireless stations to be connected through the MAC layer within a single collision domain without interference. This makes it possible for all of the stations to share the same channel.…”

An Intelligent Distributed Channel-Aware Medium Access Control (IDCA-MAC) protocol is proposed for Home Area Network (HAN), in general, and for Electrical Devices Networks (EDN), in particular, in smart grids. In an EDN, electrical devices generate critical packets, and these must be communicated to their respective mesh clients. The proposed IDCA-MAC protocol employs simultaneous transmission of data packets through a single collision domain. Also, the electrical devices and the mesh client are assumed to be equipped with Multiple Input Multiple Output (MIMO) technology. The proposed protocol is compatible with the existing IEEE 802.11 standard, and uses channel-aware Medium Access Control (MAAware) and the Zig-Zag decoding algorithm. Simulations are carried out using the NS-2 network simulator, and the performance of IDCA-MAC protocol is evaluated for various smart grid scenarios that are of practical significance. It is shown that the protocol is very effective and can be easily adopted in existing smart grids for improved throughput and performance.

“…This group is responsible for specifying standards for media access control (MAC) and physical (PHY) layers of the OSI (Open Systems Interconnection) reference model. The basic 802.11 MAC protocol is a Distributed Coordination Function (DCF) component that operates as a listen-before-talk scheme, based on the Carrier Sense Multiple Access (CSMA) [3][4][5][6].…”

In wireless local area networks, management decisions concerning channel selection, rate selection, and power management have a profound impact on the throughput performance, particularly in dense areas. These measurements, however, are too weakly associated with the MAC layer to be able to make such management decisions. Therefore, direct measurements of the channel quality at the MAC layer are necessary to facilitate appropriate decision-making activities. Estimating quantities, such as the probability of collision and the probability of channel-induced errors, will enable the MAC layer to make suitable decisions1. This paper proposes a mechanism to calculate both the channel error probability and collision probability through the methodology of distribution. Some scenarios are discussed to demonstrate the effectiveness of the measurements.
