example

[0045] In the design of this gateway, the records of the neighbor list of the route of each sub-gateway mainly include the following information:

[0046] Neighbor node address (id): the address used to identify each neighbor node.

[0047] Current parent node (parent): record the current forwarding node address of the neighbor node.

[0048] Path cost (cost): the path cost from the neighbor node to the sink node.

[0049] Child node flag (childLiveliness): used to identify whether the neighbor node is a child node of the local node, and the child node cannot be selected as a forwarding node, that is, a parent node, to avoid loops.

[0050] Number of connections (links): How many connection branches the neighbor node has, that is, how many nodes choose it as the parent node.

[0051] Number of lost messages (missed): the number of messages lost by the neighbor node.

[0052] Number of messages received (received): The number of messages received by the neighbor node, the nu...

Abstract

The invention relates to a sensor network multi-protocol gateway, which comprises receiving subnet gateways corresponding to front-end sense networks, a front-end sense network management main gateway, and a topology management gateway, wherein the receiving subnet gateways are used for networking through searching different front end structures or protocol network node signals in a multi-protocol network manner so as to establish the front-end sense networks, and realizing communication between the same network nodes through route selection; the front-end sense network management main gateway is respectively connected with the receiving subnet gateways, and is used for distributing routing information for the receiving subnet gateways, and forming a multi-path network for maintaining a routing relation between the receiving subnet gateways so as to establish communication between the front-end sense networks; and the topology management gateway is used for establishing communication between the front-end sense networks and rear-end equipment or network. The gateway realizes the efficacy of data receiving of a multiple network protocol and network routing of a multi-type heterogeneous network, and overcomes the limitation of access capability of the front-end sense networks in the prior art, so that the front-end sense networks are mutually connected and communicated.

Description

technical field [0001] The invention relates to the network field, in particular to a heterogeneous network self-adaptive data communication method and a sensor network multi-protocol gateway applied to the Internet of Things. Background technique [0002] The most basic and largest part of the Internet of Things is the front-end sensors, which are deployed in large numbers in or near the perceived objects in various ways to form distributed sensor nodes (groups). However, different sensors have different network transmission methods, and they themselves do not have a unified data transmission method. As a result, if technology development companies want to use different sensors to collect data, they must build different transmission gateways at the front end to meet the needs of data transmission. [0003] However, the current Internet of Things gateway can only initially solve the transmission problem of different collected data for the above problems. For example, a sing...
