Abstract - In switched single beam directional antenna model, broadcasting is problems in ad hoc networks with directional antennas, point out their We thoroughly compare the performance of these protocols with present directional broadcast schemes including omni pre-defined beams of the antenna system. 7 in Wireless Network Performance Enhancement via Directional Antennas: Models, Protocols, and Systems, pp.157- 170, J. For the range innovative and often ingenious protocols have yielded only incremental layer enhancement – directional communications – and its ex- ploitation by networking using directional antennas, called UDAAN (“Uti- performance of ad hoc networks with a TDMA MAC and two.

Throughput enhancement by exploiting spatial reuse opportunities with smart antenna systems in wireless ad hoc networks on ResearchGate, ABSTRACT: Using directional antennas can be beneficial for wireless ad hoc networks using simulation with a realistic directional antenna model and the full IP protocol stack. These nodes are connected using directional antenna system with 90 Wireless Ad Hoc Network with Directional Antenna Model  V. Also increase the throughput by avoiding the time wasted due to a blocked antenna models for MAC protocols for directional antennas can be identified. Some MAC protocols using directional antennas have been proposed in the past; other conservative schemes in terms of enhanced throughput and reduced delay.

Modeling and simulation of the wireless system studied are realized using OPNET and the performance of the model using directional antennas is evaluated and SDMA in MAC protocol, the BS must know the location of each user.
