Dear Murtadha Shukur ,

Recently, we carried out a study on smart cities and we found out that software-defined Networking (SDN) and Network Functions Virtualization (NFV) can markedly improve handover performance and reduce latency through advanced network management and virtualization techniques. SDN's centralized control plane facilitates real-time optimization of routing paths and efficient allocation of network resources during handovers, thereby minimizing packet loss and ensuring low-latency transitions.

Concurrently, NFV enables the deployment of virtualized network functions at the edge, closer to end-users, which accelerates the processing of handover requests and reduces latency. The synergistic integration of SDN and NFV in smart city infrastructures allows for dynamic, adaptive, and scalable network operations, significantly enhancing the seamless connectivity and user experience in highly mobile and data-intensive environments.

I hope this gives a perspective.

Yes, SDN and NFV can potentially enhance handover performance and decrease latency in various ways. For example, in an SDN-enabled edge computing environment, effective strategies for access point (AP) handover can be implemented based on the received signal strength indicator (RSSI) and traffic load. This can not only improve the time taken to complete tasks but also reduce energy consumption. Similarly, NFV enables the optimization of resource allocation and load balancing, resulting in smooth handovers and addressing the issue of high latency in wireless LANs. Furthermore, the joint optimization of resources in Mobile Edge Computing (MEC) systems can further minimize energy consumption and delays.
