Neighbor discovery in network with directional antennas

Bilgin, Yusuf Alper
Yılmaz, Ali Özgür
Using directional antennas in wireless networks has become a popular approach due to its benefits. However, since the existing MAC protocols were not designed to work with such antennas, when the existing protocols are used, the network capacity may even deteriorate rather than improve. In this paper, a neighbor discovery algorithm has been proposed for a system using directional antennas. A discovery algorithm proposed by [1] has been studied and its efficiency has been improved by making some changes. With directional antennas finding the neighbor can be a knotty problem, since when and where to point the beam is really critical for communication. Some proposed systems use GPS, omnidirectional antennas or time synchronization to solve these problems. However, the proposed system in this paper needs neither GPS nor omnidirectional antennas. It does not depend on time synchronization either.

Distributed sensor networks have been discussed for more than 30 years, but the vision of Wireless Sensor Networks (WSNs) has been brought into reality only by the rapid advancements in the areas of sensor design, information technologies, and wireless networks that have paved the way for the proliferation of WSNs. The unique characteristics of sensor networks introduce new challenges, amongst which prolonging the sensor lifetime is the most important. WSNs have seen a tremendous growth in various applicati...
Smart Neighbor Scanning with Directional Antennas in 60 GHz Indoor Networks
Olcer, Gencay Mutlu; Genc, Zulkuf; Onur, Ertan (2010-09-30)
The 60 GHz technology has an immense potential to provide wireless communication at multi-gigabit rates. At 60 GHz frequency band, severe attenuation of the signals can significantly degrade communication performance. To cope with the attenuation problem, directional antennas with high directive gains can be utilized. When network nodes use directional antennas, the neighbor discovery process becomes more complicated and time consuming. To reduce the neighbor discovery time, we propose a smart neighbor scan...
Finding sensing coverage and breach paths in wireless sensor networks
Onur, Ertan; Delic, H (2004-01-01)
Most of the recent studies on wireless sensor networks deal with the communication coverage. However, for the surveillance wireless sensor networks, sensing coverage is an open research area. In this paper, the sensing coverage area of surveillance wireless sensor networks is studied. The sensing coverage is determined by applying Neyman-Pearson Detection Model and Dijkstra's shortest path algorithm is applied to find the weakest breach path. Although individually not enough, breach probability is an approp...
Event-driven MAC Protocol For Dual-Radio Cooperation
Khatibi, Arash; Durmus, Yunus; Onur, Ertan; Niemegeers, Ignas (2012-01-01)
One of the sources of the energy waste in wireless sensor networks is idle listening, the time in which a node monitors the free channel. In applications where the events occur sporadically, energy consumption due to idle listening can be further reduced by dual-radio cooperation. In dual-radio cooperation, nodes in the network have two stacks. One stack makes use of a low-power wake-up radio for event-driven communication over the main radio. The other stack may employ any sensor networking medium access c...

Hasan, Mohammed Zaki; Al-Rizzo, Hussain; Al-Turjman, Fadi (2017-01-01)
The vision of wireless multimedia sensor networks (WMSNs) is to provide real-time multimedia applications using wireless sensors deployed for long-term usage. Quality of service assurances for both best effort data and real-time multimedia applications introduced new challenges in prioritizing multipath routing protocols in WMSNs. Multipath routing approaches with multiple constraints have received considerable research interest. In this paper, a comprehensive survey of both best effort data and real-time m...
