The management of internet of things (IoT) objects through a self-describing interoperability framework is described. In one example, a method for self-described object management includes communicating, by an internet of things (IoT) object, a request to register the IoT object, receiving, by the IoT object, an inquiry from an IoT management system, and communicating, by the IoT object, a self-describing declaration to the IoT management system. The self-describing declaration can include an interface parameter schema for the IoT object and an operating parameter schema for the IoT object, among other data structures. The method can also include establishing an interoperability framework between the IoT object and the IoT management system based on the interface parameter schema and the operating parameter schema. Based on self-describing declarations from various IoT objects, a number of different IoT objects can be easily recognized, integrated with, and managed by the IoT device management system.

Internet of things management through self-describing objects

Various examples are disclosed for hybrid alert and action solution in internet-of-things (IoT) networks. A computing environment can generate an alert and an action to perform when criteria associated with the alert is satisfied based at least in part on data collected from at least one of a plurality of sensor devices. The computing environment can determine whether the alert and the action is capable of being evaluated and performed on an edge computing device in communication with the at least one of the plurality of sensor devices based at least in part on a computing capability of the edge computing device or the at least one server computing device. The computing environment can assign the alert criteria and the action to the edge computing device or the at least one server computing device.

A computing environment is configured to divide a search query into at least a first sub-query and a second sub-query. A first service and a second service are created to execute the first sub-query and the second sub-query and identify search results from a first one and a second one of the databases, respectively, in parallel. For instance, in response to the first set of search results being placed in the first queue, the second one of the services can execute the second subquery on a second database while the first service performs subsequent queries. A final result of the search query can be generated based at least in part on the second set of search results in the second queue.

Successive database record filtering on disparate database types

The management of internet of things (IoT) objects through a self-describing interoperability framework is described. In one example, an IoT object can be registered with an IoT device management system. The IoT device management system can then query the IoT object for a self-describing declaration. The self-describing declaration can include a schema that defines certain operating and interface parameters for the IoT object. The IoT device management system can parse the self-describing declaration to determine, for example, both normal or expected and abnormal or pathologic data from the IoT device. The self-describing declaration can also define function call parameters to establish an interoperability framework between the IoT device management system and the IoT object. Based on such self-describing declarations from various IoT objects, a number of different IoT objects can be easily recognized, integrated with, and managed by the IoT device management system.

An approach is disclosed for registering and authenticating Internet of things (IoT) devices. In one embodiment, an installation device receives, from an IoT device, an identifier (ID) and a hash of a public key, where the IoT device itself generates the ID, the public key, and a private key. To register the IoT device, a blockchain wallet in the installation devices generates a blockchain transaction which adds the received ID and hash of the public key as a name and value pair in a name/value storage (NVS). The hash of the public key may then be retrieved from the NVS and used in authentication of the IoT device to other IoT devices or servers, among other things.

A system and method for ensuring non-interfering garbage collection in a real time multi-threaded environment. An incarnation counter is associated with a scoped memory area. The incarnation counter is atomically updated upon access by a no heap thread not interruptible by garbage collection operations. A write stub is identified and includes instructions to store data into storage locations of the scoped memory area. The instructions are dynamically modified to interrupt execution of a garbage collection thread. A garbage collection thread is executed over the scoped memory area. At least one of a read from the scoped memory area and a write to the scoped memory area are attempted. For the read attempt, an incarnation number is read from the incarnation counter of the scoped memory area and is locally stored. A value from a storage location in the scoped memory area is loaded and the incarnation number is reread. The reread incarnation number is compared with the locally stored incarnation number. The garbage collection thread is interrupted when the reread and locally stored incarnation numbers fail to match. For the write attempt, the instructions in the write stub are executed. The instructions include one of storing data into one such location in the scoped memory area and interrupting execution of the garbage collection thread.

An invention is provided for a synchronous transfer of control. An asynchronous interrupt exception is received, and in response, the value of a reference counter is determined. The value of the reference counter is based on the execution of synchronized code. Generally, the reference counter is initialized to a predetermined number, and altered based on the execution of synchronized code. When the asynchronous interrupt exception is received, the method is asynchronously interrupted when the value of the reference counter is equal to the predetermined number.
