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 virtual repulsive force strategy. To enhance the localization accuracy, the surveillance area is divided into grids and the grid based virtual repulsive force is applied to the MN if it is located in an anchor dense area. The simulation results show that defining a grid based virtual repulsive strategy increase the localization accuracy and cover more surveillance region using less energy.

Path Planning and Localization for Mobile Anchor Based Wireless Sensor Networks
Erdemir, Ecenaz; Tuncer, Temel Engin (2017-09-02)
In wireless sensor networks, anchor positions play an important role for accurate localization. For mobile anchor ( MA) based scenarios, both the efficiency of the path planning algorithm and the accuracy of the localization mechanism are critical for the best performance. In this work, an adaptive path planning algorithm is proposed based on Gauss-Markov mobility model, while the sensors are localized using alternating minimization approach. Path planning, which combines the velocity adjustment, the perpen...

This study is focused on a new approach for addressing the trade-off between accuracy and energy-efficiency of Wireless Multimedia Sensor Networks. Although a number of previous studies have focused on various special topics in Wireless Multimedia Sensor Networks in detail, to best of our knowledge, none presents a fuzzy multi-modal data fusion system, which is light-weight and provides a high accuracy ratio. Especially, multi-modal data fusion targeting surveillance applications make it inevitable to work ...
An Adaptive, energy-aware and distributed fault-tolerant topology-control algorithm for heterogeneous wireless sensor networks
Deniz, Fatih; Yazıcı, Adnan; Bağcı, Hakkı; Department of Computer Engineering (2016)
Wireless sensor networks (WSNs) are being used in numerous fields, such as battlefield surveillance, environmental monitoring and traffic control. They are typically composed of large numbers of tiny sensor nodes with limited resources. Because of their limitations and because of the environments they are being used, there are problems unique to WSNs. Due to the error-prone nature of wireless communication, especially in harsh environments, fault-tolerance emerges as an important property in WSNs. Also, bec...
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...
