1. An experimental verification of single-frequency networks in multi-hop ad hoc networks
Kandidat-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystemSammanfattning : A multi-hop ad hoc network requires no infrastructure, like base stations or routers to function. This means that it can quickly be deployed and in movement, making it ideal for scenarios like natural disasters or battlefield communication. LÄS MER
2. Impact of Extended DRX Cycles on Battery Lifetimes and UE Reachability
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Several UE energy consumption optimization techniques have been proposed for Machine Type Communication (MTC) devices. Extended Discontinuous Reception (eDRX) in idle mode is one such technique wherein an UE in idle mode wakes up only during its Paging Occasion (PO) to monitor paging messages from eNodeB (eNB).

3. Cooperative Diversity and Power Consumption in Multi-hop WSN : Effects of node energy on Single Frequency Networks
Master-uppsats, Avdelningen för informations- och kommunikationssystemSammanfattning : At the present time, wireless sensor networks are becoming more and more common and energy consumption is a key factor in the deployment and maintenance of these networks. This thesis compares non-SFN multi-hop and a single frequency network (SFN) or cooperative diversity algorithms with respect to the energy consumed by the nodes. LÄS MER
4. IP Multicasting over DVB-T/T2/H and eMBMS using PARPS : Effect of the number of transmitters
Master-uppsats, Avdelningen för informations- och kommunikationssystemSammanfattning : With the advancement in the current wireless technology standards such as terrestrial digital video broadcasting systems (DVB-T, DVB-T2, and DVB-H) and the massive usage of the Internet over mobile devices, streaming of television channels in smart phones has become a necessary advancement for mobile users. As, UMTS dominating the entire mobile market globally and with the evolution of LTE, several mobile operators are working on an MBMS framework which will help to launch mobile TV services on respective operators.

5. Design and Evaluation of SFN based Distributed Cooperative Routing Protocol : for Multihop Adhoc Networks
Master-uppsats, Avdelningen för informations- och kommunikationssystem; Institutionen för informationsteknologi och medierSammanfattning : Multi-hop ad-hoc networking paradigm is expected to be the key feature in future wireless communication systems. In a typical data broadcast scenario multi-hop ad-hoc routing protocols tends to allow devices to communicate and form networks in a manner to enable them to successfully communicate and share information with all the nodes.
