A Survey of IoT Management Protocols and Frameworks

Abstract: As the complexity of Internet of Things (IoT) systems increases, a large variety of tools and technologies for IoT management are making their way into both research setups and the market. IoT management solutions must consider the resource restrictions of embedded devices, as well as their heterogeneity and network dynamics. With these in mind, the Internet Engineering Task Force developed several standards targeting the integration and interoperation of heterogeneous devices, such as the Representational State Transfer Configuration Protocol (RESTCONF) or the Constrained Application Protocol (CoAP) Management Interface. Concurrently, the Open Mobile Alliance developed the Lightweight Machine-to-Machine protocol, for IoT device management. This paper provides a comprehensive, up-to-date overview of IoT management technologies, frameworks and protocols. Also, it proposes a taxonomy for IoT devices management. In addition to presenting the various solutions, the paper provides comparative views, standardization timeline, and market analysis. The presented analysis ranges from traditional network management protocols, such as Simple Network Management Protocol, to the newest IoT management and configuration protocols, such as CoAP Management Interface and Lightweight Machine-to-Machine protocols. Moreover, this survey identifies remaining challenges and solutions offered by recent management protocols, not covered by previous surveys.

Method and system for key distribution and authentication in a data communication network

Abstract: This invention deals with a safe key distribution and authentication in a data communication network (e.g. wireless LAN type of network). The network includes a network manager to which are connected, via a LAN wired circuit, one or more base stations. Individual remote stations are, in turn, wirelessly connected to an installed base station. One essential function for achieving security in such a network, is a mechanism to reliably authenticate the exchanges of data between communicating parties. This involves the establishment of session keys, which keys need to be distributed safely to the network components. An original and safe method is provided with this invention for key distribution and authentication during network installation, said method including using the first installed base station for generating a network key and a backbone key, and then using said first installed base station for subsequent remote station or additional base station installations while avoiding communicating said network key.

Decentralised approaches for network management

Abstract: Centralised network management has shown inadequacy for efficient management of large heterogenous networks. As a result, several distributed approaches have been adapted to overcome the problem. This paper is a review of decentralised network management techniques and technologies. We explain distributed architectures for network management, and discuss some of the most important implemented distributed network management systems. A comparison is made between these approaches to show the pitfalls and merits of each.

Wireless gateway supporting a plurality of networks

Abstract: In accordance with various aspects of the disclosure, systems and methods are illustrated for an apparatus comprising a modem component, a wireless communications component, at least one processor, and at least one tangible electronic memory storing data and numerous computer-executable modules to enable wireless hotspots with multiple network identifiers. Examples of at least some of the computer-executable modules includes, but is not limited to an input module, network identifier module, session management module, network management module, automatic location management module, authentication module, bandwidth negotiation module, billing interface module, and activity-based location module.

Managing application services over service provider networks: architecture and dependency analysis

Abstract: This paper proposes a novel approach for managing IP-based services and applications, reflecting the authors' experience with the IBM Global Network. It describes how one can extend the existing network and systems management paradigms to address problems in the management of application services hosted by network service providers (NSP). We introduce the concept of "service management domains" which are virtual domains built from resources and dependency relationships pertaining to physically monitored domains in the network management layer. They form the basis for managing fault, performance and service level agreements related to application service offerings.
