Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] in the attached figure 2 Among them, nodes s1, s2, and s3 perceive the target event, and send data to their cluster head node a through CSMA. If other nodes also perceive the target time, and if three nodes have reported data, they will discard their own data packets. Node a performs data fusion after receiving the data, and then transmits the fusion data to node b during the working hours of node b, and so on. Finally, the data reaches the sink node through the tree structure. It can be seen that the sleep scheduling does not bring additional delay overhead to data transmission.

Abstract

The invention belongs to the field of wireless sensor networks, in particular to a wireless sensor network distributed clustering and sleep scheduling method specific to target detection. The invention aims to decide the sleep mechanism of a network node according to the clustering structure of a network specific to the application of the target detection in order to realize low end-to-end delivery delay. The method mainly comprises partition of the clustering structure, sleep scheduling of nodes and the like. Through adoption of the method, the problem of great increase in the end-to-end delivery delay caused by network sleep scheduling is solved, and a low-delay and low-energy-consumption sleep scheduling mechanism is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network protocols, and in particular relates to a dormancy scheduling method for target detection in a clustered wireless sensor network. This method is mainly used to optimize the dormant scheduling based on two tasks of target detection and data transmission in wireless sensor networks, so as to achieve the purpose of improving the end-to-end packet delivery delay characteristics. Background technique [0002] In recent years, wireless sensor networks have developed rapidly since they received extensive attention from theories and industries, and various new technologies about wireless sensor networks have also received much attention. [0003] A wireless sensor network usually consists of a wireless sensor node (sensor node) and a sink node (Sink node). Sensing nodes need to periodically sample environmental information or detect target events. If target events are detected, they need ...
