Mobile communication systems beyond 3G will comprise cellular and self-organizing networks. In this paper an appropriate migration path towards the convergence of these two network types is highlighted and the resulting common radio network architecture is presented. By means of example scenarios the way to beneficially combine both network types will be described. Thereby, transport oriented a...

Synonyms Cellular Network Security Related concepts and keywords Cellular networks; MMS worms; Social Networking; Targeted Patching Definition Worms in cellular networks are malicious codes that can exploit social relationship among mobiles for propagating, and can be effectively contained by targeted patching. Background While the increased openness in cellular networks allows richer applicati...

One of the crucial demanding factors for WiMAX wireless networks is to provide broadband services all over the geographic region. With an increase in distance the achievable carrier to interference Ratio (CINR) declines which point to non line of sight (NLOS) and decrease the signal. This paper discusses an analytical dimensioning approach and feasible planning techniques. Cell planning feature...

It is well-known that the performance of Web-browsing as well as mobile applications (or apps) suffers on today’s cellular networks. In this work, we perform a systematic measurement study of more than 50 popular apps and 2 cellular networks, and discover that while cellular networks have predictable latency, it is the path between exit points of cellular networks (e.g., GGSN) and cloud-servers...

Systems-level understanding of cellular dynamics is important for identifying biological principles and may serve as a critical foundation for developing therapeutic strategies. To date, numerous developments of therapeutics have been based on identification and comprehensive analysis of cellular dynamics, especially in the involved pathways. In cancer therapy, for instance, many researchers ha...

in this paper, the energy efficient resource allocation in noma-based heterogeneous cellular network(hcn) systems is investigated. since energy consumption and its limitations is one of the important challenges in fifth generation of cellular networks (5g), we propose a resource allocation problem which allocates power and subcarriers to multiple users to achieve the best system energy efficien...
