[0067] Example

[0068] Such as figure 1 As shown, taking the moving target detection application of wireless sensor network as an example, the MAC protocol uses IEEE 802.11b DCF, and the specific data collection method includes the following steps:

[0069] 100. Local data fusion generates source nodes.

[0070] In a wireless sensor network, an event, for example: a moving target appears in the wireless sensor network, may be detected by multiple wireless sensor nodes. Before these nodes report detection results to the sink node, local data fusion is required. On the one hand, data fusion can improve the accuracy of detection results. On the other hand, after data fusion, the amount of data that needs to be reported to the sink node can be reduced, thereby reducing the energy overhead of the wireless sensor network. Step 100 specifically includes the following steps:

[0071] 110. After the node detects the event, it writes the event type, time of occurrence, local location, and st...

Abstract

The invention discloses a method for acquiring data of a wireless sensor network based on a mobile sink node in the technical field of wireless sensor networks. The method comprises the following steps that: wireless sensor nodes which detect the same event perform local data fusion and generate a source node; the source node distributes state data packets in a predetermined direction in a unicast mode and selects a data distributing node; a sink node selects a proxy node and forwards a query data packet in the direction vertical to the predetermined direction in a multicast mode; the data distributing node which receives the query data packet prepares event data and transmits the event data to the proxy node; and the proxy node transmits the event data to the sink node. By using the method, non-valid data generated by the mobile sink node in the process of acquiring the data of the wireless sensor network can be reduced effectively and energy consumption of the wireless sensor network can be reduced, so that the service life of the wireless sensor network is prolonged.

Description

technical field [0001] The invention relates to a method in the field of network technology, in particular to a data collection method of a wireless sensor network based on a mobile convergence node. Background technique [0002] Advances in technologies such as micro-electromechanical technology, computer technology, and wireless communication have promoted the rapid development of low-power, multi-functional sensors, enabling them to integrate multiple functions such as information collection, data processing, and wireless communication in a small volume. The wireless sensor network is composed of a group of nodes integrating sensors, data processing units and communication modules, forming an ad hoc network system through wireless communication. Its purpose is to collaboratively perceive, collect and process the information of the sensing objects in the network coverage area, and send the sensing results to the sink node (Sink). [0003] In emergency environments such as...
