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...
A Survey on Multipath Routing Protocols for QoS Assurances in Real-Time Wireless Multimedia Sensor Networks 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...
An Efficient Fuzzy Fusion-Based Framework for Surveillance Applications in Wireless Multimedia Sensor Networks Sert, Seyyit Alper; Yazıcı, Adnan; Coşar, Ahmet; Yilmazer, Cengiz (2014-08-08) 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 ...
Multi-objective evolutionary routing protocol for efficient coverage in mobile sensor networks Attea, Bara'a A.; Khalil, Enan A.; Coşar, Ahmet (2015-10-01) Individual sensors in wireless mobile sensor networks (MSNs) can move in search of coverage region for the sensing accuracy and for reaching the most efficient topology. Besides, sensors' clustering is crucial for achieving an efficient network performance. Although MSNs have been an area of many research efforts in recent years, integrating the coverage problem of MSNs with the efficient routing requirement that will maximize the network lifetime is still missing. In this paper, we consider the coverage op...
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...
