Abstract

The invention discloses a node cooperative work method based on the sensing direction guide in an Internet of things environment and mainly relates to an effective realization method monitored by an object in a multimedia sensor network. Based on a sensing node perceived radius theory and a video sensing model which are provided by the invention, the method is combined with practical application and meets different practical monitoring requirements according to two work modes of group and individual provided by different scenes. By elaborating a direction guiding method in the wireless multimedia sensor network from two views of theory and practicability and combining the characteristics of easy manipulation, conciseness, high efficiency, cost saving, low expenditure and energy consumption, high flexibility and the like of the wireless multimedia sensor network, the invention provides constructive suggestions for the application of the multimedia sensor network in the monitoring field.

Description

technical field [0001] The invention relates to the guidance of the sensing direction of wireless multimedia video sensor network nodes in the sensor field of the core technology of the Internet of Things and a processing method for cooperative work among various sensor nodes, and belongs to the intersecting field of embedded development and Internet of Things technology. Background technique [0002] The Internet of things (The Internet of things) is to connect any item with the Internet according to the agreed agreement through radio frequency identification (RFID) and infrared sensors, global positioning systems, laser scanners and other information sensing devices for information exchange and communication. Communication, to achieve intelligent identification, positioning, tracking, monitoring and management of a network. The two core technologies of the Internet of Things are radio frequency identification technology and sensor network technology. [0003] Wireless Sen...
