A Comparison Study of Omnidirectional and Directional MAC Protocols for Ad Hoc Networks
, 2002
"... Traditional MAC protocols used in ad hoc networks employ omnidirectional antennas. Recently, directional antennas have emerged as an alternative due to their capability of spatial reuse, low probability of detection, robustness to jamming, and other beneficial features. In this paper, we conducted a ..."

Evaluations of A Directional MAC Protocol for Ad Hoc Networks
"... Many wireless ad hoc networks exploit MAC protocols with conventional omni-directional antennas. Smart antennas, however, improve performance by avoidance of radio interference and effective use of limited resources of mobile nodes. This paper proposes a MAC protocol using a directional beam form fo ..."

DSDMAC: Dual Sensing Directional MAC Protocol for Ad Hoc Networks with Directional Antennas
"... Abstract—Applying directional antennas in wireless ad hoc networks can theoretically achieve higher spatial multiplexing gain and, thus, higher network throughput. However, in prac-tice, deafness, hidden-terminal, and exposed terminal problems are exaggerated with directional antennas, and they caus ..."

, and they cause the degradation of the overall network performance. Although there are several random-access-based medium-access control (MAC) protocols being proposed in the literature for networks with di-rectional antennas, the deafness, hidden-terminal, and exposed terminal problems have yet to be fully
A distributed asynchronous directionalto-directional MAC protocol for wireless ad hoc networks
- IEEE Trans. Veh. Tech
, 2009
"... Abstract—The use of directional antennas in ad hoc networks has received growing attention because of its high spatial reuse and high antenna gains. The medium access control (MAC) protocol design with directional antennas is nontrivial due to the deafness and collision problems. The existing protoc ..."

Fang Y. SDMAC: Selectively Directional MAC protocol for wireless mobile ad hoc networks. Wireless Networks 2009
"... Abstract Using directional antennas in wireless mobile ad hoc networks can greatly improve the transmission range as well as the spatial reuse. However, it will also cause some problems such as deafness problem and hidden terminal problem, which greatly impair the network per-formance. This paper fi ..."

first proposes a MAC protocol called Selectively Directional MAC (SDMAC) that can effec-tively address these problems and significantly improve the network throughput. Then two improvements on SDMAC are proposed. The first one is to improve the network throughput by scheduling the packets in the queue
An Energy-Efficient MAC Protocol for Wireless Sensor Networks

, 2003
"... In this paper we describe T-MAC, a contention-based Medium Access Control protocol for wireless sensor networks. Applications for these networks have some characteristics (low message rate, insensitivity to latency) that can be exploited to reduce energy consumption by introducing an active/sleep du ..."

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 ..."

relatively few proposals for W-LANs. In this paper we present a rate adaptive MAC protocol called the Receiver-Based AutoRate (RBAR) protocol. The novelty of RBAR is that its rate adaptation mechanism is in the receiver instead of in the sender. This is in contrast to existing schemes in devices like
