Path planning and localization for mobile anchor based wireless sensor networks
Erdemir, Ecenaz; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2017)
In wireless sensor networks, sensors with limited resources are distributed in a wide area. Localizing the sensors is an important problem. Anchor nodes with known positions are used for sensor localization. A simple and efficient way of generating anchor nodes is to use mobile anchors which have built-in GPS units. In this thesis, a single mobile anchor is used to traverse the region of interest to communicate with the sensor nodes and identify their positions. Therefore planning the best trajectory for th...
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...
Path verification in software-defined networks using programmable data planes
Bostan, Hakan; Onur, Ertan; Department of Computer Engineering (2022-1)
Software-Defined Networks (SDNs) revamp the traditional network architectures by segregating the data plane and control plane and introducing a programmable and log- ically centralized control plane. Although SDNs bring along extensive improvements, as well as solutions to some of the network security problems, the security of SDN itself is often overlooked. Especially the security of the data plane is often overlooked because of the widespread assumption that the data plane devices are trusted. How- ever, ...
Band-to-Band Transition Based On-Chip Optical Modulator
Gövdeli, Alperen; Sarihan, Murat Can; Karaca, Utku; Kocaman, Serdar (2018-10-04)
Photonic crystal slab phase shifter based, area efficient and low operation voltage optical modulator design is presented. Required index difference between the Mach-Zehnder interferometer arms of the proposed modulator comes from the photonic band transition.
