## 6 Conclusions  
5G mobile communication is created by establishing the hierarchical cellular connection between cellular devices, and the physical 5G communication is configured in the physical medium using the 256 QAM Modulation and Beamforming antenna. The software-defined network (SDN) is used to virtualize the network function. This research work aims to integrate and implement the 5G network for monitoring the thermal imaging of solar farms through drone's inspection. Multicast communication between the users and the server is generated by forming the multicast tree in the network layer as IP multicast using particle swarm optimization. Descriptions are distributed across the multicast tree during the video transmission process. IP multicast minimizes the unnecessary transmission of

replicated packets in the network and the delay is minimized and packet error is lower to forward the packet. Here the video multicast servers are represented as internet servers that send a packet in multicast routing containing information about its description which is forwarded to the controller, and the transmission is completed using the SDN which also monitors and optimizes the video transmission. The video optimizer service is deployed at the edge of the 5G network with video traffic filtering. The video traffic is forwarded from a load balancer to the optimizer which handles the management plane as an efficient assignment of node addresses to active users of the infrastructure using the dynamic host control protocol service; also, the cognitive framework continuously quantifies the congestion degree of the network at a fine-grained level using a congestion index. When the congestion index surpasses the threshold, then it is processed by the cognitive layer leading to the application of the filtering rule in the associated optimizer.
