Network Management in Heterogeneous IoT networks

Heterogeneous networks (hetnets) is an interconnectionof distinctive networking paradigms to enable widerreachability and greater collaborations. In large Internet-of-Things (IoT) applications, many wireless networks are spatiallyco-located and intertwined forming hetnets; for instance, healthmonitoring devices utilising ZigBee or IEEE 802.15.4 co-exist in2.4 GHz spectrum alongside Wi-Fi devices. Interoperability ornon-obtrusive operations are required among the disjoint domainsto achieve operational efficiency in overall IoT ecosystem.Specifically, network interoperability in hetnets assure desiredreachability, resource orchestration and network quality. Inthis work, we have modelled and implemented a simulationenvironment for hetnets to support different schemes of networkinteroperability under distributed and centralised managementof network. The implementation has been evaluated for networkscalability and reliability to replicate large IoT hetnets. Byevaluating against increasing number of nodes in the hetnet,the mean latency under distributed management is improved by100-fold with the centralised management. Similar observationscould also be made for throughput and packet loss rate
