A distributed-type video cooperation scheduling method based on a wireless sensor network

Abstract

The invention discloses a distributed-type video cooperation scheduling method based on a wireless sensor network, and collaborated cooperation of a plurality of video nodes is adopted. Scheduling is conducted in a dynamic and self-adaptive mode, and an appropriate video sensor node is selected to carry out present video transmission. In a state without invasion, a system works in a static state scheduling state, and the nodes enter semi-activation states by turns according to the time assigned by a system scheduling server. When an invasion state occurs, and an invasion area is determined firstly according to dynamic group scheduling, and nodes in other areas maintain in dormancy states; and redundancy nodes are made to enter the dormancy states according to a CPNS algorithm. Acquisition transmission nodes are in activation states, and other nodes in the area enter the half-activation states. According to the method, a centralized type scheduling method and the distributed type scheduling method are combined, and through the provided method, problems in the aspects such as node energy consumption, energy equalization and transmission management of video acquisition transmission nodes are preferably solved, and the rationality and the energy equalization of video transmission in the wireless sensor network are raised.

Description

technical field [0001] The invention relates to a distributed video collaborative scheduling method based on a wireless sensor network, which is suitable for the application field of perimeter protection in which typical sensor detection and video monitoring are combined in the wireless sensor network. Background technique [0002] Wireless sensor networks are widely used in both military and civilian applications. In general, wireless sensor networks usually require continuous work for a long period of time without changing batteries. Optimizing energy consumption, such as minimizing sensor and communication energy consumption to prolong the lifetime of the entire network is an important design goal of wireless sensor networks. For distributed video sensor nodes in sensorless networks, compared with other low-power sensors, their energy consumption is relatively large. If the video node in the wireless sensor network is always in the active state, the energy consumption i...

Problems solved by technology

For distributed video sensor nodes in sensorless networks, compared with other low-power sensors, its energy consumption is relatively large.

If the video node in the wireless sensor network is always in the active state, the energy consumption is over, and the node fails quickly, the entire wireless sensor network system will not work.
