Abstract
Conference Title: 2018 25th International Conference on Telecommunications (ICT) Conference Start Date: 2018, June 26 Conference End Date: 2018, June 28 Conference Location: Saint Malo, France Mobility management has become crucial in highly dynamic environments. As mobility traffic grows, handover rates between cells and different technologies increase. Handover has been studied extensively in order to enhance mobile users' perceived services. Mobile IP (MIP) is a standard protocol that handles handover efficiently in conventional networking. Recently, as Software Defined Networking (SDN) paradigm steps in, its impact on mobile networks has been studied, and it indeed benefits mobility management. To exploit the advantages of SDN and MIP, a merge of them is needed, which requires the modification of MIP. In this paper, we study a modified version of MIP protocol in a hierarchical architecture, taking into consideration metrics such as delay, packet loss, and throughput. We show that a hierarchical setting betters handling handover between heterogeneous networks. Our algorith's performance shows improvement in decreasing total delay if the hierarchical architecture is applied compared to a distributed architecture.
