Medium Access Control Protocols using Directional Antennas in Ad Hoc Networks

Using directional antennas can be beneficial for wireless ad hoc networks consisting of a collection of wireless hosts. To best utilize directional antennas, a suitable Medium Access Control (MAC) protocol must be designed. Current MAC protocols, such as the IEEE 802.11 standard, do not benefit when using directional antennas, because these protocols have been designed for omnidirectional anten...

Evaluation of a BIBD Based Directional MAC Protocol for Wireless Ad Hoc Networks

The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...

Spatial reuse and collision avoidance in ad hoc networks with directional antennas

The quest for efficient medium access control (MAC) protocols for multi-hop ad hoc networks has aroused great interest in using directional antennas. Some MAC protocols using directional antennas have been proposed in the past, which trade off spatial reuse and collision avoidance via a combination of omnidirectional and directional transmission modes. In this paper, it is argued that the benef...

Power-controlled medium access for ad hoc networks with directional antennas

Directional antennas have the potential to significantly improve the throughput of a wireless ad hoc network. At the same time, energy consumption can be considerably reduced if the network implements per-packet transmission power control. Typical MAC protocols for ad hoc networks (e.g., the IEEE 802.11 Ad Hoc mode) were designed for wireless devices with omnidirectional antennas. When used wit...

Minimizing the effect of deafness and hidden terminal problem in wireless ad hoc networks using directional antennas

In this work we addresses the issue of deafness and hidden terminal problem in Mobile Ad Hoc Networks (MANETs) using directional antennas. To minimize these effects, we propose a MAC protocol for directional Antennas (MDA) which employs a novel Enhanced Directional Network Allocation Vector (EDNAV) scheme and, and an efficient technique of Diametrically Opposite Directions (DOD) transmission of...

Throughput enhancement in wireless ad hoc networks with spatial channels a MAC layer perspective

Use of directional antennas in cellular wireless networks offers many advantages such as range extension, reduced interference for signal detection and improved throughput. Recently, MAC protocols using directional antennas for wireless ad hoc networks that are based on and similar to IEEE 802.11 type WLANs have been proposed. In this paper, we explore ’multiplexing in space’ with directional a...
