IoT Networks QoS Guarantee

Buffer space management is critical to ensuring full utilization of network resources in present IoT networks. It allows the multiplexing of services with different quality of service requirements. Current IoT technologies supports a wide range of services including medical treatment, preventive equipment maintenance, remote operation of machinery, environmental monitoring, video surveillance and real-time alerts, connected transport as well as multiplexed services consisting of combinations of these. Traffic prioritization plays an important role in quality of service management in all mobile networks. From a network perspective, the aim is to ensure a minimum waiting time for packets of higher priority classes in the buffers of these networks. In order to use the resources correctly, it is necessary for each type of traffic or service to share the traffic capacity depending on the quality of service requirements they have.
