“…It is important to note that most works which have studied the problem of user/neighbor discovery using directional antennas have modeled antenna radiation pattern in a particular direction as a two dimensional (2D) circular sector (see [13], [14], and the references therein). From a handheld device/computer perspective, it is more appropriate to model an antenna beam feature as a threedimensional (3D) sector [15] (for an example, see Fig. 1).…”

“…The work in [22] has studied 3D statistical channel model for mmWave, and [15] has studied connectivity trade-offs in 3D wireless sensor networks using directional antennas. The work in [23] considers directional antenna orientation model in 3D space and an algorithm is proposed which can calculate the pointing angles for a non-horizontal aligned antenna.…”

Use of smart directional antennas in handheld devices to generate a narrow beam in different directions for mmWave/TeraHertz communications present significant challenges. Devices using such antennas may have to scan several different directions in three-dimensional (3D) space to discover another user or an access point, a process that can result in problematic delays. Moreover, small movements of a user/device in the form of rotation and/or displacement may cause the discovered link to be lost. This paper proposes adaptive link discovery algorithms for devices in both infrastructure/ad hoc networks and evaluates their performance in terms of timeto-discovery. We show that one of the two proposed methods provides guaranteed discovery. We use an inertial measurement unit sensor to help intelligently rediscover a lost/degraded link. We propose sensor assisted link prediction methods for lowlatency rediscovery in 3D space. We evaluate the effectiveness of our prediction-based rediscovery methods by testing them with real datasets representing various user/device 3D rotation patterns. We show that the smoothing based rediscovery can reach the prediction accuracy to 100% when two antenna sectors are searched, and it reduces the time-to-rediscovery by up to Sx (S times) as compared to the time-to-discovery, where S is the number of antenna sectors.

“…The apex angle of a spherical sector with solid angle Ω is defined as the maximum planar angle between any two generatrices of the spherical sector. It is usually represented by 2θ, see [16] for additional details. The apex 2θ and solid angle Ω are related by the following important identity due to Archimedes.…”

Abstract. The interdisciplinary understanding required for the design and analysis of underwater acoustic sensor networks presents formidable constraints and challenges for computer scientists and engineers. However, underwater environments have never been much of a constraint to the rich animal life they support at all depths of our seas and oceans. Indeed, it is known that nature has taken advantage of this environment to develop a rich variety of efficient communication strategies throughout the long history of evolutionary change and adaptation. The wealth of knowledge to be discovered will continue to dazzle and fascinate the world. For the communications in underwater sensor networks, acoustic signaling is the preferred choice for designers because sound propagation is the most efficient when compared to other forms, like thermal, light, and electromagnetic. It is within this acoustic environment that researchers have to innovate and develop new ideas and methodologies so as to advance the state-of-the-art. In this position paper, several fundamental issues and connections are discussed that arise in the study of underwater wireless sensor networks. Throughout the nature of the underwater environment is emphasized how one can take advantage of it. A variety of ideas and solutions that could be of value for further research is proposed. Moreover, fundamental issues in topology control, directional underwater transducers, and monitoring and surveillance are discussed.

Efficient coverage and connectivity are two important factors that ensures better service quality especially during tracking targets or monitoring events in wireless sensor network. Although massive amount of studies has been carried out in the past to enhance coverage and connectivity issues, till date very few studies have witnessed a significant and standard outcomes that can opt further. Hence, this paper introduces a computationally efficient technique for jointly addressing both coverage and connectivity problems in large-scale wireless sensor network that ensures optimal network lifetime too. The proposed system has been empirically designed, and algorithms formulated to ensure energy efficient monitoring of event. The outcomes of the study are compared with standard energy efficient hierarchical protocol to benchmark the results.
