*5.3. MGMS IoT Integrated*

MGMS was also revolutionized by the high penetration of IoT devices, especially in HEMS, which motivates the effective contribution of MG in DR through AMI and smart meters. This enhancement provides an infrastructure to schedule each home appliance inside MG to participate in DR resulting in a rocketing number of nodes. 5G technology based on MIMO characteristics can support communication with this number of nodes. LoRaWAN according to its lower power consumption, high data rate, and secure communication is another appropriate candidate for smart monitoring [81,82].

Figure 4 depicts an effective roadmap for applying wireless technology elements in MGMS, including communication specification, application, standards, and new technologies' requirements of MGMS.

#### **6. Future Work**

During an evolution towards MAS and multi-MG, emerging system interconnection has increased the operation and maintenance of communication infrastructure. Wireless communication enhancement with the introduction of new approaches such as 5G has been providing a solution to tackle this problematic issue by conservation cost of the system through network slicing and cloud concepts. Future work will conduct a determination of MGMS service-level requirements mapping into a service-driven 5G network and in a holistic approach for cloud-based communication structures for multi-MG and MAS investigation with wireless communication and IoT assistance.
