Feasibility of SDN-based vertical handover between bluetooth and Wi-Fi

Modeling of Seamless Vertical Handover Mechanism using Demanded Resource Identification & Mapping

“…Further study towards optimization was carried out by Liu et al [17] which basically performs selection of optimal network for minimizing computational load using software defined network. Such form of network and its feasibility was also investigated by Nyugen-Duc and Kamioka [18] considering real-time testbed of personal area network. Vuchkovska and Jakomosi [19] have addressed the problems of delay during vertical handover considering the case study of specific networking technologies e.g.…”

Unified and fast handover authentication based on link signatures in 5G SDN‐based HetNet

“…However, this multi‐tier architecture also results in quite frequent handovers, which will pose great challenges for handover authentication between different APs especially for services with stringent latency requirements [2, 3]. Existing standardised handover authentication schemes are achieved in the upper layer with different authentication protocols and message flows involved for different handover scenarios [4], introducing high complexity and excessive latency which may be intolerable for some time‐sensitive services when applied to 5G HetNet [5]. Therefore, unified and fast handover authentication schemes applicable to different handover scenarios are urgently required.…”

“…In addition, complex public cryptographic techniques are involved in most of these schemes, which cannot be well applied in resource‐constrained devices [3]. Some argue that the handover authentication could be implemented at lower layers, such as the data link layer or physical layer [5], without involving in different authentication protocols and layer‐to‐layer transfers.…”
