Device-to-Device (D2D) communications has a great potential to bring major performance improvement to the present day heterogeneous network by reutilizing the cellular resources. Handover between the devices can be made more efficient when integrated in the Software-Defined Network (SDN). In the proposed work, Exemplary Handover Scheme during D2D Communication (EHSD) architecture based on SDN principles is considered. A new Handoff mechanism based on the parameters Signal-to-Interference-and-Noise-Ratio (SINR), System Load (SL), and Time of Association (ToA) Combination (SLTC) is formulated for execution of handoff. The conveyed mechanism reduces the number of unnecessary handoff, minimizes the packet loss and balances the load guaranteeing Quality of Service (QoS). The simulation results are examined and comparative analysis is carried out on the D2D handover based on SLTC scheme, D2D Handover and cellular handover in an SDN.
