Abstract

During recent years usage of Wi-Fi communications were increasing rapidly not only in commercial areas but also in private households. With increasing number of Wi-Fi devices a new kind of problems appeared, mostly related to poor Wi-Fi throughput or communication problems. In this paper an investigation on Wi-Fi networks in Vilnius City and it's surrounding is presented, covering the main problems of Wi-Fi network saturation and load during day. Also an investigation on dependence of Wi-Fi saturation on noise levels was made, showing the impact of neighbor AP to SNR. Ill. 7, bibl. 7 (in English; abstracts in English and Lithuanian).

Performance Investigation of Data Packets Transport Control Protocol in Heterogeneous Networks

“…Also the issue of TCP acknowledgment overhead in network nodes will be discussed and what new implementation or modifications could reduce TCP overhead and improve the TCP efficiency and speed in high utilized or overloaded networks. The research results are published in author publications: Pavilanskas et al (2015); ; Statkus et al (2012). The main results are announced in scientific conferences: "Electronics" (Vilnius 2011), "Communication and Information" (Barcelona 2013).…”
