Abstract

The present invention is a method and framework for protocol to optimize edge side dynamic response system with context propagation for IoT. The protocol is a composition of a set of predefined routines, called ‘parlance’, that control the lifecycle of the meshed devices. The master has characteristics to store database as block chains, encryption using hash function, run defined duty cycles. The edge devices have characteristics to receive parlance, execute parlance, provide data to mantles.

Claims

1. A system for optimizing edge side dynamic response with context propagation for Internet of Things (IoT), comprising:

one or more devices, each connected to a first master in an IoT star topology network;

wherein the first master is configured to receive a copy of a distributed database, comprising one or more actions from a second master, and to confirm the one or more actions, resulting in one or more confirmed actions;

one or more bloks, each blok configured for storing one or more confirmed actions;

wherein the first master is adapted to validate the one or more bloks using hash functions; and

wherein the first master is adapted to transmit the one or more bloks to the second master and to update the distributed database and a memory database with activity information contained within one or more bloks.

2. The system of claim 1, further comprising a database storing unconfirmed actions.

3. The system of claim 2, wherein the public-key cryptography scheme is based on difficulty of factoring large integers.

4. The system of claim 1, wherein contents of an action is secured through a public-key cryptography scheme.

5. The system of claim 1, wherein the distributed database comprises a secure list of all actions.

6. The system of claim 5, wherein the bloks are stored in the distributed database in chronological order.

7. A method for providing a dynamic one-the-edge heterogeneous Internet of Things (IoT) network, comprising:

providing a network with one or more systems, each system having one or more devices, each connected to a master in an IoT star topology network;

receiving a copy of a distributed database comprising actions at a first master of a first system;

validating, by the first master of the first system, the distributed database using hash functions;

receiving a blok, storing one or more confirmed actions, at the first master of the first system;

validating the blok by requiring the blok solve a partial hash inversion problem;

updating the distributed database and a memory database with activity information contained within the blok; and

transmitting the blok to a second master of a second system.

8. The method of claim 7, further comprising the step of:

storing the blok in the distributed database.

9. The method of claim 7, further comprising the steps of:

receiving an action at the first master;

relaying the action to the blok; and

securing contents of the action through a public-key cryptography scheme.

10. The method of claim 9, wherein the public-key cryptography scheme is based on the difficulty of factoring large integers.

11. The method of claim 7, further comprising the steps of:

receiving a first action at the first master;

transmitting the first action to a memory database; and

receiving a second action at the first master; and

determining if the second action is a duplicate of the first action stored in the memory database.

12. A computer program product providing content on multiple virtual displays, the computer program comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions are readable by a computer to cause the computer to perform a method comprising the steps of:

providing a network with a first system having one or more devices connected to a first master in an Internet-of-Things (IoT) star topology network;

adding a second system having one or more devices connected to a second master in an IoT star topology network;

receiving, by the second master, a copy of a distributed database comprising actions from the first master;

validating, by the second master, the distributed database using hash functions;

transmitting a blok from the first master to the second master;

validating, by the second master, the blok using hash functions; and

updating the distributed database and a memory database with activity information contained within the blok.

13. The computer program product of claim 12, further comprising the step of securing the blok through a public-key cryptography scheme based on the difficulty of factoring large integers.

14. The computer program product of claim 12, further comprising the step of propogating the blok in the network.

15. The computer program product of claim 12, wherein the actions are included in bloks.

16. The computer program product of claim 15, wherein the bloks are stored in the distributed database in chronological order.

17. The computer program product of claim 12, further comprising the steps of:

receiving a new action at the second master; and

determining if the new action is a duplicate of an activity information contained in the memory database.

18. The computer program product of claim 17, further comprising the step of including the new action in a blok.

19. The computer program product of claim 17, further comprising the step of notifying the one or more devices when an action is included in a blok.

20. The computer program product of claim 12;

further comprising the steps of;

receiving a new action from the one or more devices; and

relaying the new action created by the one or more devices to the network.
