The increasing world population has increased the demand for food. Many threats such as agricultural land use, environmental impacts, global warming and drought risks necessitate industrialization of agricultural production and optimum utilization of existing …

Wireless sensor network (WSN) is a distributed system usually comprising a set of autonomous sensors nodes. These sensors are physically small in size and are capable to communicate with each other and capable of conveying data to recipients. In a large number…

Wireless Sensor Networks have many application fields including both industrial and military usages. They are used for monitoring temperature, distance, light, and motion in laboratories and/or application specific environments. This paper focuses on developin…

Wireless Sensor Networks, used widely nowadays, are likely to be unprotected against a variety of external attacks because they are often used in outdoor applications. Protecting the network against attack and ensuring the safety of the data has always been im…

We propose using support vector machines (SVMs) as a machine learning classifier in a grain-conditionmonitoring system. This system is used to proactively monitor the silobag-stored grain condition. The system consists of a wireless sensor network (WSN) and a …

Kablosuz Sensör Ağları, sürekli olarak çevreden topladıkları bilgileri ana ana düğüme oradan da sunucu veya ana toplayıcıya göndermektedirler. Ağ yapısı büyüdükçe ağ içerisinde meydana gelen veri transferinin boyutu da ciddi artış göstermektedir. Eğer ağda res…

Monitoring and management of storage and material consumption processes in silo systems. In this study, a CAN BUS-based sensor network was developed for the control of silo systems, the filling and discharging of materials into silos and the protection of mate…

Increasing in wireless communications systems is caused to increase in the need of the frequency spectrum. CR (Cognitive Radio) measure or sense frequency spectrum activities on spectrum bands whether they are idle or used by licensed users. According to sensi…

Günümüzde birçok alanda kullanılan Kablosuz Algılayıcı Ağlar genellikle açık alan uygulamalarında kullanıldıkları için dışarıdan gelen farklı saldırılara karşı korumasız durumda olabilirler. Ağı saldırılara karşı korumak ve verilerin güvenliğini sağlamak, Kabl…

Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…

In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…

The popularity of wireless communication is increasing day by day. This has led to the fact that data transfers via GSM have reached very high levels. Data transfers via GSM, which are continuously growing, increase the density of data traffic, thus necessitat…

With the rapid development of technology and the importance of electronic devices in our lives, electromagnetic waves produced by various sources and the related electromagnetic pollution concepts have become an important issue that directly affects the nature…

This study presents a Hybrid Digital-Physical Risk Management Framework designed to enhance urban climate resilience through the integration of Industry 4.0 technologies. By combining real-time IoT sensor networks, AI-based predictive analytics, and blockchain…

In this paper, a singular-feed circularly polarized (CP) metasurface antenna with broad impedance bandwidth is presented. The antenna consists of modified slots with a lattice of 3 × 3 square conductive patches. Modes are selected and excited by modified slot …

The monitoring of emissions caused by congested road traffic requires the deployment of a complex measurement system. The use of Wireless Sensor Networks (WSN) can be very useful. In this work we propose the architecture of sensors (devices) which are envisage…
