Improving throughput in DMM with mobile‐assisted flow mobility

Abstract

The development of new applications and mobile devices has increased the data traffic in cellular networks and required throughput improvements, which can be achieved through heterogeneous access networks, where multimodal user devices able to establish simultaneous connections with different access networks are considered. Such connections and data offloading between Wi‐Fi and cellular networks provide load balancing and increase the throughput of heterogeneous cellular networks. Offloading can be performed at the network layer through the move of Internet Protocol (IP) flows, and mobility management solutions can be used as a basis for this purpose. This article proposes an architecture called Seamless IP Flow and Distributed Mobility Management (SIFDMM), which is based on a distributed mobility management solution and improves heterogeneous network throughput by moving IP flows between Wi‐Fi and LTE networks. SIFDMM mitigates congestion in the networks and causes no problem of single point of failure, scalability, and reliability of centralized solutions. An analytical comparison was performed for an effective demonstration of the throughput improvement in heterogeneous networks.

SDN‐DMM for intelligent mobility management in heterogeneous mobile IP networks

“…The addition and use of new protocols, signaling messages, or processes that cause overhead because of the encapsulation and control traffic are examples of how the mobility management directly impacts on the Operational Expenditure (OPEX) and Capital Expenditure (CAPEX) of a communication network.An alternative for dealing with the intrinsic problems of centralization and costs in the mobility management is the new concept, called distributed mobility management (DMM). 8,9 Its main characteristic is the clear separation between the data plane and the control plane. The data plane is distributed along the equipment on the access network edge for approximating the mobile agent to the end user, implementing a flatter mobility approach in the network.…”

SDN-FHOR-DMM: a software defined network (SDN)-based fast handover with the optimal routing control method for distributed mobility management (DMM)

“…To meet the trend of more and more mobile users, IETF has proposed the other network-based method called the distributed mobility management (DMM) [6,7] architecture to resolve the anchor entity issue for tackling the aforementioned problems. DMM has been designed for handling mobility management based on distributing the mobility functions of both the control and data planes, which are separately situated in the core and access network.…”

“…Thus, DMM can offer an effective technique to improve the network scalability and the handover performance. Several works have been proposed to resolve related problems existed in the DMM architecture [7,8]. Similarly to Centralized Mobility Management (CMM), the key obstacle for DMM is maintaining the on-going communications while mobile users roam among distinctive networks [9][10][11][12][13].…”
