Data forwarding control method, device and system

Abstract

The invention discloses a data forwarding control method, device and system. The data forwarding control method comprises the following steps: receiving the summarized information of data forwarding capability of each sensor node, wherein, the summarized information is sent by each mobile gathering point; according to the summarized information, generating a two-dimensional matrix about the mobile gathering points and the sensor nodes; processing the two-dimensional matrix by a competitive algorithm, and ensuring that each line in the two-dimensional matrix contains one nonzero value at most,i.e. each sensor node contains one mobile gathering point at most to forward data; and according to the processing result of the two-dimensional matrix, pairing the sensor nodes and the mobile gathering points. The data forwarding control method, device and system are characterized in that the mobile gathering nodes and the sensor nodes requiring data forwarding are subjected to one-to-one data forwarding pairing, so that the mobile gathering node has balanced load, and the phenomena of route blockage of certain mobile gathering node and quick exhaustion of energy can be eliminated.

Description

technical field [0001] The present invention relates to a communication network technology, in particular to a data forwarding control method, device and system. Background technique [0002] In a wireless sensor network, there are generally two types of nodes as follows: one is a sensor node (Sensor Node), which is equipped with various types of sensors and is responsible for detecting and sensing the surrounding environment; the other is a sensor node. As the sink node (Sink Node), this type of node has the function of collecting information from other sensor nodes. And it is usually equipped with more than two network interfaces. On the one hand, it communicates with the underlying wireless sensor network nodes through the wireless sensor network interface, and on the other hand, it accesses the upper layer network through the connected Ethernet or wireless network. [0003] Aggregation nodes are further divided into fixed aggregation nodes and mobile aggregation nodes. ...

Problems solved by technology

[0005] 1. It is generally assumed that the sensor node selects the mobile sink node by itself. Therefore, in the scenario of multiple mobile sink nodes, multiple source nodes all choose the same mobile sink node for data forwarding, resulting in an unbalanced load state, resulting in Routing congestion of a sink node and rapid depletion of energy;

[0006] 2. This disordered state of autonomy of each sensor node will intensify competition and conflict, especially when there are a large number of sensor nodes, this competition and conflict will reach an unbearable level for the system, and because each node needs to monitor other nodes The communication state not only wastes the precious limited energy of sensor nodes, but also deteriorates the data forwarding delay
