Seamless mobility in IoT world using software defined networks
Existing mobility protocols adopt centralized gateways to provide session continuity for mobile users. The centralized nature and the absence of effective selective traffic offload mechanism lead to inefficient data forwarding plane problem that congests 4G Evolved Packet Core (EPC). Despite the end...

| description | Existing mobility protocols adopt centralized gateways to provide session continuity for mobile users. The centralized nature and the absence of effective selective traffic offload mechanism lead to inefficient data forwarding plane problem that congests 4G Evolved Packet Core (EPC). Despite the endless efforts of 3GPP, IETF, vendors, and researchers, these problems persist and restrict operators’ offering for residential/enterprise indoor services and session continuity in wide area motion as train or cars crossing cities’ boundaries. Existing mobility protocols, that struggle when connecting mobile users to static locations, can never satisfy the requirements of Internet of Things (IoT) for real time collaborative interactions between moving users and terminals attached to 5G edges as drones, robots, smart vehicles …etc. New mobility paradigm becomes a key enabler for collaborative interactions in IoT real time cognitive services as self-driving car, drones, remote health monitoring, smart homes/offices/farms …etc. The research provides a novel mobility framework based on Software Defined Network (SDN) to solve existing mobility problems, satisfy IoT collaborative interactions, and extend mobility coverage cross service providers under Service Level Agreements (SLAs) while ensuring the security of involved entities. Mobility is achieved through dynamic establishment of SDN overlay network that can cross any type of LAN/WAN/Cellular topology. The framework is fully aligned to Next Generation Network (NGN) where mobility is offered as a service and provides smooth integration to existing infrastructure. The mobility scope incorporates both intra-domain and inter-domain mobility. The former refers to mobility within a single SDN administrative domain while the later refers to that between multiple SDN domains. Intra-domain mobility scope targets existing mobility challenges as core network congestion problem, unified access in campus and enterprise for wireless/wired networks, and session continuity in standard and wide area motion for 3G/4G/5G mobile operators. Inter-domain mobility scope addresses three main challenges. The first is extension of indoor services for residential/enterprise using any type of communication as DSL/cable without enforcing Distributed Antenna System (DAS) or any small cell setup while ensuring the security of involved entities. The second is extending WiFi mobility cross enterprises with optimized usage of communicating WAN links while ensuring unified access to both wireless and wired networks regardless of overlapping configurations as IP subnets/VLAN that can exist in their intranets. The third is facilitating collaborative communication between static/moving users, servers, and terminals when joining from different carriers under Service Level Agreements (SLA). |
