Abstract

A method for managing communications between internet of things (IoT) nodes in an IoT environment having an IoT hub includes identifying candidate smart devices in the nodes using a service request high power initiator node. Based on the parameters of the initiator node, the smart device can flexibly operate as a low-power or high-power device, a hybrid device. The method may include selectively assigning the smart device as a trusted designated node within the IoT environment. The method also includes determining an optimal period for status message delivery from the trusted designated node to the IoT hub based on the parameter. Thereafter, the method includes transmitting the status message to the hub via the trusted designated node at an optimal period such that the trusted designated node acts as a proxy for the initiator node when reporting the status message to the hub.

Description

Method for managing interaction between intelligent Internet of things center and nodes Introduction to the invention Advances in global automation technology have led to adoption of internet of things (IoT) based solutions and associated management of a large number of networking device types for implementing IoT environments. Devices in a networked IoT environment and their communication nodes are used to collect and exchange messages, thereby enabling automation and optimizing the processes performed by the devices. For example, a "smart garage" IoT network connection may be used to schedule and manage residential charging operations for battery electric vehicles or plug-in hybrid electric vehicles. Such networks may utilize smart phone based monitoring and open/close operation of garage doors or other access points, control of climate settings such as temperature, humidity and air quality, and monitoring/control of other networked systems. IoT networks may be used in other operating environments including, but not limited to, a user's home or office. Modern industrial and manufacturing environments may also use networked IoT ecosystems to facilitate order placement, track assembly progress, or otherwise communicate between different networked devices. Communication between nodes of a networked IoT environment relies on proximity ranging and reliable exchange of other information via coordinated exchange of electronic signals or messages. Networking devices/nodes may rely on one or more connection technologies, such as Wi-Fi, bluetooth Low Energy (BLE), cellular, zigbee, or other technologies, to communicate such ranging data and information. Coordinated operation of potentially different technologies across the networking IoT environment is currently facilitated by the open source Matter standard, and thus the networking IoT ecosystem is often referred to as a Matter network. Regardless of the architecture or subnetwork used in the networked IoT ecosystem, the constituent nodes of the ecosystem are required to periodically communicate with the IoT hub to maintain state within and control of the ecosystem. Disclosure of Invention The present disclosure relates to methods and systems for managing and controlling a networked internet of things (IoT) ecosystem having one or more IoT hubs and a plurality of networked intelligent devices. Each smart device includes/acts as one or more communication nodes within the IoT ecosystem. As used herein, an IoT hub is a centralized hardware and software device that connects and manages ongoing data/message exchanges between connected IoT devices. In different implementations, the IoT hub may be local or global/cloud-based, thus acting as a centralized communication node during exchange of messages between connected devices. Several examples of such messages include activation or deactivation commands, telemetry data, performance metrics, software/firmware updates, error conditions, status, security credentials, time stamps, health status reports, and other related information or data. In accordance with aspects of the present disclosure, in various embodiments, the trusted designated node is dynamically or statically assigned by a service request device ("initiator node") or IoT hub. The allocation occurs based on parameters of the initiator node, such as its current power level or state of charge. Thereafter, the designated node is used as a "trusted node" as part of the IoT ecosystem, particularly for the purpose of providing status messages to the IoT hub on behalf of the initiator node. As disclosed herein, the term "hybrid device" refers to a high power smart device, such as an Electric Vehicle (EV) or a controller having multiple processors/other computing nodes. Sometimes, high power devices may experience a depleted battery or reduced energy budget and thus begin to behave more like low power devices. Thus, when the initiator node/smart device is an EV, the designated node negotiates an optimal engagement period with the IoT hub using parameters in the form of a reduced capacity level or state of charge of a propulsion battery of, for example, an Electric Vehicle (EV). In the non-limiting case of the example EV and its built-in propulsion battery, during the ignition-off mode of the EV, periodic messaging between the EV and IoT center may rapidly discharge and further deplete the propulsion battery or another onboard energy storage system for that purpose. To address this issue, the methods set forth herein include selectively introducing trusted designated nodes into the IoT environment as trusted nodes and messaging agents. In different embodiments, the task of selecting a trusted designated node is performed by the service request initiator node/device or by the IoT hub as needed. Thereafter, the incoming trusted designated node acts as a proxy for status reports and other message exchanges with the IoT hub, and negotiates the optimal periodicity of such re
