Wireless Multimedia Sensor Networks (WMSNs) are characterized by large number of resource constrained camera sensors. In remote surveillance applications, such resource constraints necessitate the design of lightweight solutions for traditional problems such as object localization and real-time tracking. In this paper, we propose an energy-efficient object localization and multiple object tracking scheme for WMSNs. The object localization is performed by individual camera sensors. For that purpose, the approach first extracts the detected object from the video frame and finds its boundary using frame differencing. The location of the object is then estimated with the help of the camera sensor's location, distance of the object to the camera and camera/frame size properties. After localizing a detected object, its boundary information is used to perform a fuzzy object classification at the camera sensor. Finally, limited information containing the location and classification of the object are transmitted to the sink node to be used in real-time object tracking. In this way, without receiving the raw video data from the camera sensors, the sink can identify a specific object even though its information may come from several camera sensors at different times, and determine its path for the purpose of tracking. Via extensive simulations, the proposed approach has been shown to provide higher localization and identification accuracies with little cost on camera sensors even under low camera coverage.

Implementation of an Enhanced Target Localization and Identification Algorithm on a Magnetic WSN Baghaee, Sajjad; GÜRBÜZ, SEVGİ ZÜBEYDE; Uysal, Elif (2015-10-01) Wireless sensor networks (WSNs) are ubiquitous in a wide range of applications requiring the monitoring of physical and environmental variables, such as target localization and identification. One of these applications is the sensing of ferromagnetic objects. In typical applications, the area to be monitored is typically large compared to the sensing radius of each magnetic sensor. On the other hand, the RF communication radii of WSN nodes are invariably larger than the sensing radii. This makes it economic...
Efficient active rule processing in wireless multimedia sensor networks Oztarak, Hakan; Akkaya, Kemal; Yazıcı, Adnan; Sarisaray-Boluk, Pinar (Inderscience Publishers, 2016-01-01) Due to limited energy resources in wireless multimedia sensor networks (WMSNs), there is a need to perform data reduction and elimination over raw video data at the camera sensors before transmission. Nonetheless, this data reduction and elimination may create imprecision and uncertainty in the data, reducing the quality of decision making. In this paper, we propose a reactive mechanism for not only fusing uncertain data at the sink but also for automated processing of data using active rules, extending the...
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...
Analysis and modeling of routing and security problems in wireless sensor networks with mathematical programming İncebacak, Davut; Baykal, Nazife; Bıçakcı, Kemal; Department of Information Systems (2013) Wireless Sensor Networks (WSNs) are composed of battery powered small sensor nodes with limited processing, memory and energy resources. Self organization property together with infrastructureless characteristics of WSNs make them favorable solutions for many applications. Algorithms and protocols developed for WSNs must consider the characteristics and constraints of WSNs but since battery replenishment is not possible or highly challenging for sensor nodes, one of the major concerns in designing network p...
Effective Use of Low Power Heterogeneous Wireless Multimedia Sensor Networks for Surveillance Applications Using IEEE 802.15.4 Protocol Kenges, Nurdaulet; Ever, Enver; Yazıcı, Adnan (2021-01-01) With the recent technological advancements in video sensors, digital signal processing units and digital radio interfaces, low-cost devices such as Wireless Multimedia Sensor Networks (WMSNs) became an important part of surveillance applications. The scarcity of resources for these devices introduces new challenges in terms of energy consumption, and Quality of Service (QoS) guarantees. One of the challenges is processing and transmission of large volumes of multimedia data. In this paper, the efficiency of...
