Cellular and Sensor Networks

Cellular and Sensor Networks
The research activities of the group led by Prof. Wiesław Ludwin are focused on mobile cellular networks and wireless sensor networks (WSNs). 
Regarding cellular networks, two main research lines are carried out. The first one concerns the process of mobile networks planning and optimization, which is analyzed in the context of the general concept of self-organizing networks (SON), developed by 3GPP. In particular, the research is focused on issues of radio network parameters self-adaptation to changing operational conditions, including the volume and density of telecommunications traffic. Moreover, under the framework of ETSI standardization, the research group is involved in the development of a model for Generic Autonomic Networking Architecture (GANA).The second research line deals with radio links optimization. It is concentrated on the design of advanced algorithms, which enable differentiation of the complexity of signal equalizers used in radio receivers, allowing the use of additional stage of adaptive signal correction in case of worsening conditions in the radio channels. 
As to WSNs, the research group works on transmission protocols and specific applications of large-scale networks of sensors and actuators. The first area of interest is wireless localization for WSNs both in outdoor (intelligent antenna arrays and angle-of-arrival techniques are considered) and indoor (measurements performed for a receive-signal-strength WSN-based system) environments. The second one concerns geographic routing protocols using the location knowledge from localization algorithms. The group also works on the cooperation schemes for large sensor and actuator networks. The last topic is about WSN applications, especially distributed intelligent networks designed for forest fire detection and extinguishing. 
The research group strictly collaborates with a large number of European research institutions, e.g. University of Bologna, France Telecom, Technical University of Cartagena, University of Castilla La Mancha, Aalto University School of Electrical Engineering and University of Girona.

Informacje dodatkowe: 

Wiesław Ludwin uzyskał stopnie zawodowe i naukowe: magistra inżyniera i doktora nauk technicznych na Wydziale Elektrotechniki Automatyki i Elektroniki Akademii Górniczo-Hutniczej odpowiednio w roku 1978 i 1983, a w 2005 roku - stopień doktora habilitowanego w dyscyplinie telekomunikacja specjalność radiokomunikacja w Wojskowej Akademii Technicznej w Warszawie. W latach 1978-1986 pracował w Instytucie Automatyki, Inżynierii Systemów i Telekomunikacji. Obecnie jest profesorem w Katedrze Telekomunikacji AGH w Krakowie. Jego zainteresowania naukowe koncentrują się na problemach dotyczących łączności radiowej. W szczególności obejmują zagadnienia projektowania sieci i systemów bezprzewodowych oraz modelowania i analizy ruchu telekomunikacyjnego w systemach łączności ruchomej o strukturze komórkowej. Jest autorem oraz współautorem trzech książek o sieciach bezprzewodowych i ponad 50 prac naukowych. Artykuł pt. "Is Handoff Traffic Really Poissonian?", opublikowany w listopadzie 1995 roku w materiałach czwartej konferencji IEEE International Conference on Universal Personal Communications, ICUPC'95 w Tokio, był i jest cytowany w wielu międzynarodowych publikacjach.
