Although many localization protocols have been proposed for terrestrial sensor networks in recent years, the unique characteristics of the underwater acoustic communication channel, such as high and variable propagation delay and the three dimensional volume of the environment make it necessary to design and develop new localization algorithms. In this paper, a localization algorithm called Three-Dimensional Underwater Localization (3DUL) is introduced. 3DUL achieves network-wide robust 3D localization by using a distributed and iterative algorithm. Most importantly, 3DUL exploits only three surface buoys for localization initially. The sensor nodes leverage the low speed of sound to accurately determine the inter-node distances. Performance evaluations show that 3DUL algorithm provides high accuracy in underwater localization, which does not degrade with network size.

An Adaptive Path Planning Algorithm for Mobile-Anchor Based Wireless Sensor Networks Erdemir, Ece Naz; Tuncer, Temel Engin (2017-01-01) In wireless sensor networks, anchor positions play an important role for high localization accuracy. Planning an efficient path for mobile anchor nodes (MN) is critical for required anchor positions. In this work, an adaptive path planning algorithm is proposed for mobile anchors based on Gauss-Markov mobility model. The approach, which the velocity adjustment, the perpendicular bisector and the virtual repulsive strategies are combined based on Gauss-Markov mobility, is improved by developing a grid based ...
Topology control vector based forwarding algorithm for underwater acoustic networks Yazgı, İlkay; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2015) The communication range of underwater acoustic sensor networks (UASN) is limited by the underwater environment. Acoustic networks with huge number of sensors may have long communication range with appropriate protocols in literature. On the other hand, especially, the networks including small number of nodes have communication problems for long ranges. To challenge this problem, topology control in underwater acoustic networks is a promising solution. In this study, a novel approach, Topology Control Vector...
Self-deployment of mobile underwater acoustic sensor networks for maximized coverage and guaranteed connectivity ŞENEL, FATİH; Akkaya, Kemal; Erol-Kantarci, Melike; Yilmaz, Turgay (2015-11-01) Self-deployment of sensors with maximized coverage in Underwater Acoustic Sensor Networks (UWASNs) is challenging due to difficulty of access to 3-D underwater environments. The problem is further compounded if the connectivity of the final network is desired. One possible approach to this problem is to drop the sensors on the water surface and then move them to certain depths in the water to maximize the 3-0 coverage while maintaining the initial connectivity. In this paper, we propose a fully distributed ...
Topology Control Vector Based Forwarding Algorithm for Underwater Acoustic Networks Yazgi, Ilkay; Baykal, Buyurman (2016-05-19) The communication range of underwater acoustic networks (UAN) is limited by the properties of underwater environment. Especially, the networks including small number of nodes have communication problems for long ranges. To challenge this problem, topology control in UAN is a promising solution. In this study, Topology Control Vector Based Forwarding Algorithm (TC-VBF) is proposed. The TC-VBF uses nodes' position to determine the forwarding vector. In this work, the TC-VBF is evaluated comparatively with alt...
Performance evaluation of a new cross layer protocol for sink powered underwater acoustic sensor networks Türken, Hasan; Bilgen, Semih; Department of Electrical and Electronics Engineering (2013) The term Sink Powered Underwater Acoustic Sensor Networks (SPUASN) refers to a special configuration within the recent Remotely Powered Underwater Acoustic Sensor Networks (RPUASN) paradigm, where the data sink supplies energy to battery-free sensors that constitute the network. This thesis evaluates the performance of a new cross layer protocol, Cross Layer Power Adaptive CSMA/CA (X-PACCA), proposed for SPUASN. Simulation based performance evaluation is conducted both by investigating the effects of design...
