A Directional MAC Protocol for Ad Hoc Networks

by Pan Li, Hongqiang Zhai, Yuguang Fang
"... Using directional antennas in wireless ad hoc networks can greatly improve the spatial reuse and the transmission range. However, it will cause the deafness problem, which greatly impairs the network performance. This paper proposes a new MAC protocol SDMAC (Selectively Directional MAC) that can eff ..."

Performance Analysis of Circular Directional MAC Protocol

by Woongsoo Na, Laihyuk Park, Gunwoo Lee, Sungrae Cho, Seung Eun Hong, Woo Yong Lee
"... Abstract—There have been great attentions on directional MAC (D-MAC) protocol recently in wireless ad hoc networks. Even if directional MAC has benefits such as spatial reuse and thus increased throughput, it has significant problems that have not been effectively rectified including hidden terminal ..."

Directional MAC Protocols in Ad-Hoc Networks

by Sudipta Majumder, Syed Emdadul Haque, Fernaz Narin Nur
"... In wireless ad-hoc networks, the beam forming antenna technology is a new and promising solution to many challenges. Beam forming antennas have the ability to increase the spatial reuse, improve the transmission reliability, extend the transmission range and/or save the power consumption. If they ar ..."

A directional-to-directional mac protocol for ad-hoc networks

by Emad Shihab, Lin Cai, Jianping Pan , 2008
"... Abstract — The use of directional antennae in ad hoc networks has received growing attention in recent years. However, most existing directional MAC protocols assume interchangeable di-rectional and omnidirectional modes of operation. Such operation reduces the spatial gain and introduces the asymme ..."

To solve the deafness problem and the new hidden terminal problems, in this paper, we propose an effective Circular RTR Directional MAC (CRDMAC) protocol for WANETs by using a sub-transmission channel and RTR (Ready To Receive) packets, which

A Power Control Scheme for Directional MAC protocols in MANET

by Bassel Alawieh, Chadi Assi, Wessam Ajib
"... Abstract — Higher throughput gains and prolonged life time can be achieved for mobile ad hoc networks (MANET) with nodes equipped with Directional antennas. The employment of directional antennas can enhance the spatial reuse by allowing concurrent communications to occur within the same vicinity. A ..."

The proposed scheme can be integrated to any directional MAC protocol that adopts a single channel for transmission and reception of IEEE 802.11 frames. The proposed power control scheme exploits the temporal directional

A Busy-Tone Based Directional Mac Protocol for Ad Hoc Networks
