A Flat Mobile Core Network for Evolved Packet Core Based SAE Mobile Networks

Proposal and evaluation of SDN-based mobile packet core networks

Recently, several researchers have proposed adopting software-defined networking (SDN) concepts for mobile network architectures, particularly for LTE-evolved packet core (LTE/EPC). Although several new designs have been introduced for architectures based on SDN or its concrete realization, Openflow, few studies have presented in-depth discussions of real procedures that are relevant to such ar...

Network Path and Quality Validation in the Evolved Packet Core

The Internet nowadays plays an imperative role in critical domains such as finance, health, security, entertainment and military where real-time services with guaranteed resources become necessary. Services residing within the application layer in today’s fixed and mobile network environments are abstracting from the underlying network layer, and therefore, assuming pure IP connectivity without...

Virtual-Mobile-Core Placement for Metro Network

Traditional highly-centralized mobile core networks (e.g., Evolved Packet Core (EPC)) need to be constantly upgraded both in their network functions and backhaul links, to meet increasing traffic demands. Network Function Virtualization (NFV) is being investigated as a potential cost-effective solution for this upgrade. A virtual mobile core (here, virtual EPC, vEPC) provides deployment flexibi...

Community Core Evolution in Mobile Social Networks

Community detection in social networks attracts a lot of attention in the recent years. Existing methods always depict the relationship of two nodes using the temporary connection. However, these temporary connections cannot be fully recognized as the real relationships when the history connections among nodes are considered. For example, a casual visit in Facebook cannot be seen as an establis...
