LTE- in Unlicensed Band: Medium Access and Performance Evaluation
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 Long Term Evolution (LTE) technology is challenged by high data rate demanding services and increasing number of mobile phones which are equipped with Wi-Fi access capability. To respond to this challenge, 3rd Generation Partnership Project (3GPP) initiated a Study Item (SI) which investigates the co-existence of Wi-Fi and LTE technologies in the same unlicensed 5 GHz band. Given that Wi-Fi and LTE are originally designed to operate in totally different bands, unlicensed and licensed, it is difficult to achieve this coexistence for these two incompatible access technologies. Accordingly, 3GPP introduces the…

Determining gastrointestinal tract dysbiosis using machine learning techniques
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 This thesis explores machine learning techniques for the purpose of determining gastrointestinal tract dysbiosis. Dysbiosis is an unbalance of bacteria flora. Stool sample analysis of relevant bacterias can be used in "diagnosis" of this condition. The problem is how to best classify dysbiosis from a healthy balance of bacteria. Pattern recognition methods could be used to create a diagnostic decision support system. The approach includes comparisons between classifiers with the additional use of feature reduction techniques. Experiments show that the accuracy varies significantly depending of which classif…
Neighbor and Service Discovery Protocols with Security Enhancement for Device-to-Device Communication in LTE{LTE-A Cellular Networks
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 Device-to-Device (D2D) communication has become one of the most popular topic in the 5th generation (5G) mobile communication technology. D2D offers opportunities for access to services through direct neighbor device connection with or/and without base station (BS) assistance. Some of the possible improvements using D2D communication include high data rate, network offloading and range extension, as well as commercial and social proximity services networking. Although a lot of studies exist in the research community, D2D communication with one of the end users are located outside the cellular network covera…
