“…The transmitter creates the appropriate beam patterns, depending on the location of a receiver. Some studies assume that the location of a node may be obtained using a Global Positioning System (GPS) [3,7,13,14]. Other studies assume the transmission of data through the routing layer in order to acquire information about the location of a receiver, or the location of a receiver.…”

“…Cochannel interferer suppression capabilities of smart antennas make them suitable to guarantee an improved performance in hostile environment. Several MAC protocols [5][6][7][8][9][10][11][12][13][14][15] have been already proposed in literature, to exploit spatial multiplexing capabilities of smart and directional antennas. In [5], authors consider an ideal model for the antenna radiation pattern, evaluating the protocol performance for an error free channel.…”

This paper investigates the performance of a fixed Wireless LAN in\ud which nodes are equipped with fully adaptive smart antennas. The\ud considered smart antenna system is a uniform circular array of\ud microstrip patch elements in which the weights are updated using\ud the unconstrained LMS algorithm. The behavior of a new directional\ud MAC protocol for spatial multiplexing is analyzed and compared\ud with IEEE 802.11 DCF. The paper purpose is the evaluation of\ud interference and multipath effects on SDMA, using realistic models\ud for the channel and for the smart antenna system. The link model\ud takes into account path loss, cochannel interference and\ud multipath, using a modified Jakes model. Results show that the\ud performance of the WLAN are strictly dependent on the interferer\ud characteristics and on the angular spread of the channel

Compared with omni-directional antennas, directional antennas have many merits, such as lower interference, better spatial reuse, longer transmission range, and improved network capacity. Directional antennas enable numerous emerging outdoor and indoor applications, which have been addressed in many recent studies. Despite the advances in wireless networks with directional antennas (DAWNs), there are many research challenges in all layers of DAWNs. This paper presents a detailed study on recent advances and open research issues on DAWNs. Firstly, we briefly introduce the classification of directional antennas, antenna radiation patterns, antenna modes, and the challenges in the physical layer of DAWNs. We then present research issues on the medium access control (MAC) layer, followed by the current solutions as well as open research problems on the MAC layer of DAWNs. In addition, we also discuss the research issues on the routing layer and the transport layer. Moreover, other research challenges on the performance evaluation of DAWNs and a brief introduction of indoor DAWNs are given in this paper as well. In conclusion, we summarize the current research issues on DAWNs as well as prospects in the future.
