Growing traffic and lack of efficient handover in LTE using SDN based 5G Network are two major concerns and there is a need for an integrated solution.
The Device-to-Device or D2D technology offers wireless networking of proximate devices in a peer-to-peer model that is structured on the involvement of the core networks.
The proposed research is based on the idea of combining the existing LTE-A cellular network with the proposed architecture so as to incorporate Device-to-Device communication in the 5G model.
In this proposal, an efficient handover in LTE using SDN based 5G Network is used which aims at the stability of the entire structure. The SDN is linked within LTE in a quasi-decentralized way. Also, a new handover management method is proposed that will help in enhancing QoS parameters during wireless networking.
The proposed model offers a reliable and efficient handover in LTE using SDN based 5G Network, which would eventually increase the D2D service continuity.
In the existing technology, lack of an efficient handover in LTE using SDN based 5G Networkis the biggest issue. As the current technology and handover procedures are unable to offer reliable and ubiquitous Device-to-Device communication. Some of the other drawbacks included in the current model are interrupted D2D link, latency, and overconsumption of the resources. Apart from this, high signaling is also a prevailing issue.
As per the proposed, efficient handover in LTE using SDN based 5G Network architectureof S/PGW (Serving/ Packet Gateway) is decoupled and emulates the OpenFlow switch functioning in which the GPRS Tunneling Point is removed. The SGW-C and PGW-C control parts deploy into the rules of the flow process so that the routing rule of the packet can be obtained. An OpenFlow interface integrates into the eNodeB to get a Software Defined eNodeB- SeNodeB.
Then Radio Resource Control connection is deployed where the SeNodeB frequently sends an RRC measurement control.
The algorithm for efficient handover in LTE using SDN based 5G Network is based on Reference Signal Receiver Power’s threshold value. Also, the data packets are transmitted from the D2D transmitter to the receiving device with no delay.
In the future, we aim to utilize the 5G architecture in the D2D structure of wireless networking.
