1. 1. Analyzing VoIP connectivity and performance issues

   Kandidat-uppsats,

   Författare :Mehenni Sadaoui; [2019]
   Nyckelord :VoIP; connectivity and performance issues; call quality; packet traces.;

   Sammanfattning : The appearance of Voice over IP (VoIP) revolutionized the telecommunications word, this technology delivers voice communications over the internet protocol (IP) networks instead of the public switched telephone network (PSTN), calls can be made between two VoIP phones as well as between a VoIP phone and an analog phone connected to a VoIP adapter [1]. The use of this technology gives access to more communication options compared to the conventional telephony but the users face different problems, mostly connectivity and performance issues related to different factors such as latency and jitter [2], these factors affect directly the call quality and can result in choppy voice, echoes, or even in a call failure.

3. 2. Extension of EnergyBox for LTE networks

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Gunnar Berg; [2016]
   Nyckelord :energybox; lte; mobile; networks; energy consumption;

   Sammanfattning : With the steady increase in the use of mobile technologies, studying the energy consumption of mobile applications becomes more interesting. In this thesis, the energy consumption of such applications connected to Long Term Evolution (LTE) cellular networks is studied. LÄS MER

4. 3. CheesePi: Delay Characterization through TCP-based Analysis from End-to-End Monitoring

   Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

   Författare :Rebecca Portelli; [2016]
   Nyckelord :Active IP Network traffic measurement; TCP flow analysis; network delay characterization; end-to-end monitoring; Aktiv IP-nätverk trafik mätning; TCP flödesanalys; karakterisering av nätverksfördröjning; end-to-end-monitoring;

   Sammanfattning : With increasing access to interconnected IP networks, people demand a faster response time from Internet services. Traffic from web browsing, the second most popular service, is particularly time-sensitive. This demands reliability and a guarantee of delivery with a good quality of service from ISPs. LÄS MER

5. 4. Emulating 3G Network Characteristics on WiFi Networks

   Master-uppsats, Linköpings universitet/Programvara och system

   Författare :Alexander Alesand; [2015]
   Nyckelord :Emulation; Network Emulation; Network Testing; Software Testing; Testing; UMTS; 3G; Spotify; Emulering; Nätverksemulering; Nätverkstestning; Mjukvarutestning; Testning; 3G; UMTS; Spotify;

   Sammanfattning : Mobile applications should work regardless of which type of wireless interface is used, and should be able to conceal unstable connections from the user to improve user experience. Therefore, network testing is important when developing mobile applications, but it is a challenge to reproduce network conditions when using real cellular networks since the test engineer has no control over the quality of the cellular network.
