Problems solved by technology

In addition, in the application scenario of mobile computing covered by Wi-Fi, when the terminal device enters the coverage area of ​​another subnet from one subnet as the user moves, the original network connection needs to be disconnected due to the change of the gateway. The communication cannot be continued until the IP address of the new subnet is obtained again, which has a certain impact on the delivery of mobile computing tasks

Abstract

The present invention provides a method for self-organization and cooperation of fog nodes based on mobile IP, which includes sending node information frames to management fog nodes by working fog nodes at the beginning and end of work or at regular intervals, and updating the routing table; management fog nodes according to According to the task situation, the task splitting decision is made. After accepting the task, multiple working fog nodes are combined to build the working domain; after the management fog node builds the working domain, the mobile terminal position is monitored. Request the care-of address and register with the local agent; after the task is completed, the local agent releases the occupation of the working fog node, releases the working domain and takes back the IP allocated for the mobile terminal. The method provided by the present invention enables the nodes participating in the fog computing to form a distributed computing platform in real time, adapt to the change of the workload in time, and reduce the computing delay; realize the fog node working domain group with dynamically variable topology, and provide terminals with Scalable computing resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for ad hoc cooperation of fog nodes based on mobile IP. Background technique [0002] In recent years, with the rapid development of the Internet of Things, emerging service models such as smart cities and smart homes are gradually entering people's lives. With the wide application of smart sensing devices and smart terminals, the amount of data generated and the demand for mobile computing are increasing exponentially. Therefore, offloading some tasks of cloud computing to near-user terminals for processing, while meeting the task time requirements and reducing overall operating costs, fog computing is gradually becoming a popular solution. Fog computing can extend the cloud computing paradigm to the edge of the network, and has broad application prospects in IoT services. Fog computing can effectively improve the data processing capability of the system, reduce...
