Edge-centric IoT service provisioning architecture with reliable communication over wireless mesh networks

Abstract

As the future Internet paradigm shifts to the Internet of Things (IoT), we have seen an increase in the number of things connected to the Internet over the past few years. Things are generating tremendous data used by a variety of services for user convenience. In the foreseeable future, users will be able to receive IoT services with high quality in real time via a nearby edge of wireless networks. In line with this change, this dissertation addresses an edge-centric IoT service provisioning architecture with reliable communication over wireless mesh networks (WMNs) by dividing it into three parts

discovery, service provisioning, and interaction parts. From the discovery aspect, this dissertation addresses the ID-based service and data discovery system. The system defines and breakthroughs the challenges of the existing GS1 object name service (ONS) and discovery service (DS) standards based on globally distributed architecture. For evaluation, performance was measured with the experimental test-bed and the experimental results showed the system provides reasonable performance for operation in the real environment. From the service provisioning aspect, this dissertation proposes the on-demand service provisioning edge (OSPE) framework. To overcome the challenge of legacy edges inappropriate to edge computing, it defines the edge requirements, namely, horizontal integration, on-demand service provisioning, user mobility, and resource efficiency, and OSPE framework is designed considering these requirements. For evaluation, performance was measured with the experimental test-bed and the experimental results showed it satisfies the defined edge requirements and is feasible for edge computing. From the interaction aspect, this dissertation proposes the traffic-aware stateless multipath routing (TSMR) for fault-tolerance in WMNs constructed by the edge. TSMR dynamically selects the local optimal path according to traffic flow and link loss, improving reliability. For evaluation, a simulation was carried out on NS-2, and the simulation results showed TSMR provides reliable routing with low cost despite multipath routing.
