Heterogeneous network, which consists of macro-cells and small cells, is actively researched in Long Term Evolution (LTE) area. The present handover procedure is not considered for the heterogeneous network environment. As the coverage of a small cell is limited, more frequent handovers occur. Therefore, workloads of a Mobility Management Entity (MME) and a(More)
Software Defined Network (SDN) is widely deployed by using OpenFlow protocol for the implementation of flexible networking. A lot of researches are progressing to adapt OpenFlow to existing network architectures. PMIPv6 is proposed to handle the network-based local mobility using IP tunneling. However, it has some weak points such as IP tunneling overhead(More)
