M2M Clustering Method in Urban Distribution Network (UDN) Considering Delay Sensitive Devices

In the 5^th generation network communication, by deploying UDN (urban distribution network) to increase the wireless network capacity, most of the current articles consider H2H communication under UDN, while ignoring M2M communication. M2M communication under UDN is mainly established by MTCG and core network. The MTCG deployment is based on different MTCD (machine-to-machine type communication) methods. The location and density of the MTCD is a major consideration in MTCG deployment. However, for large heterogeneous networks such as UDN, geolocation-based clustering methods are often used to enable UDNs to adapt to this complex large-scale network architecture. This paper considers the delay-tolerant devices in M2M clustering and prioritizes access to such devices.
