Abstract

The invention discloses an ad hoc network communication method, device and ad hoc network based on heterogeneous equipment of the Internet of Things. The method includes: receiving message data transmitted by a previous hop node; wherein, the message data includes: data content, Source node IP, target node IP, forwarding node IP of the last hop node, routing hops, and node performance in the ad hoc network; according to the target node IP, find out whether there is a valid route to the target node in its own routing table; If there is, then update the message data, and send the updated message data according to the effective route and the node performance of the current node; if not, start the route discovery process, and after finding an available route, update the message data message data, and send the message data according to the node performance of the current node. The implementation of the present invention can make the ad hoc network automatically resume communication after a certain node fails, and can also balance the data calculation workload of each node according to the node performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to an ad hoc network communication method, device and ad hoc network based on heterogeneous devices of the Internet of Things. Background technique [0002] At present, there are various physical network communication protocols such as MQTT, etc., and each protocol has its certain application scenarios. For example, LoRa, NB-IoT, Zigbee, and Bluetooth mainly solve the problem of Internet of Things and access to the network. From the perspective of network protocol layering, they basically belong to the data link layer protocol. For the data exchange of the Internet of Things, it mainly depends on the application layer protocol to solve. For example, the Message Queuing Telemetry Transport Protocol (MQTT: Message Queuing TelemetryTransport) is a protocol designed for a large number of sensors or controllers with limited computing power, limited working bandwidth, and unreliable net...
