A wireless sensor network node communication control system and control method thereof

Abstract

The invention discloses a system and a method for controlling communication of wireless sensor network nodes. The system adopts a modularized structural form of a TinyOS mini embedded operation system and a scheduling mechanism of an FIFO (First Input First Output). The system comprises an application layer, a wireless communication sub-system and an intertask communication sub-system, wherein the application layer comprises a plurality of task modules, an intertask communication assembly in the intertask communication sub-system establishes a communication array between the two task modules which require communication, so that the communication between the tasks is realized; the wireless communication sub-system comprises an interface layer, an adaption layer and a presentation layer, which are connected with each other in sequence; the task modules in the application layer and the interface layer have data interaction; the adaption layer is provided with a data communication logic control assembly, a channel carrier sensor assembly and a state control assembly; and the presentation layer is provided with an interface abstraction assembly connected with a communication unit. Through combination with the corresponding control method, the system and the method, provided by the invention, can reliably realize communication between the wireless sensor network nodes, and the complexity and the cost are lower.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor network node communication that can be applied to forest disaster prevention and monitoring, large-area crop growth environment monitoring and adjustment, large storage environment, smart home and other wireless sensor network application fields Control System. Background technique [0002] In the field of monitoring and control, such as forest disaster prevention and monitoring, large-scale crop growth environment monitoring and adjustment, large storage environment, smart home, etc., wireless sensor networks are more and more widely used. In practical applications, a large number of sensor nodes are generally deployed in the monitoring area for a long time, and the nodes form a network through wireless self-organization. The sensor nodes collect the required monitoring data, and transmit the monitoring data to the aggregation node according t...
