Embodiment Construction

[0058] Aiming at the technical requirements for the effective organization of massive sensors in the current Internet of Things environment, the present invention starts from the perspective of the logical link layer and uses a weighted hierarchical network model to form the basis of the "event-centered" sensor network adaptive organization and collaboration. Through this network model, the collaborative observation driven by node events is realized. On this basis. The event-driven sensor network self-adaptive mechanism is based on the event multi-mode response model. Through the event multi-mode response model, the event-to-self-organization incentive behavior is determined, and the multi-mode response, collision detection, and heterogeneous data fusion of nodes to event incentives are realized. On the basis of this model, combined with the spatial position relationship of nodes, the self-organization of the network is realized rapidly. At the same time, the optimization of...

Abstract

The invention discloses an event-driven state-oriented self-adaptive sensor organizational method which comprises the steps that 1) an one-event multi-mode response model is set, and an event is divided into a plurality of levels; 2) when node acquisition data are in a sampling value section corresponding to an event of a certain level, an event message is structured to be broadcast to the internet of things; 3) after the event message is received by other nodes, if the local caches the event message is judged, if yes, the message is ignored, if not, the event message is cached in the local and the response level and report frequency of the event message are determined, and meanwhile the node identification and address are added to a message route list for subsequent broadcast; 4) a laminated multi-way tree structure is structured according to node levels, and a complete link is structured for the event; 5) the node in the complete link transmits the data of the event to the higher level node according to the data report frequency corresponding to the response level of the node until the data are sent to the sink node. According to the method, multi-mode response of nodes and network quick organization are achieved.

Description

technical field [0001] The invention belongs to the technical field of sensor networks and the Internet of Things, relates to a self-organizing processing method of a state-adaptive sensor network, in particular to an event-driven state-adaptive sensor organization method, which is used in environmental monitoring, fire protection, and safety monitoring And other fields have positive application value. Background technique [0002] "Perceiving the world" is one of the core application values ​​of the current Internet of Things. Combined with a large number of advanced sensors, a new generation of high-speed networks and other means, the Internet of Things has played an increasingly important role in safety management and emergency response. Therefore, how to organize massive heterogeneous sensors to achieve effective situational awareness in the context of the Internet of Things has become a hot issue in the current cross-sensor and Internet of Things research fields. "Eve...
