Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in the figure, a wireless sensor network architecture with efficient cooperative sensing energy of the present invention specifically includes the following periodic steps:

[0020] A. Clustering, determine each node to become a cluster head or a cluster member;

[0021] B. The cluster heads form a tree topology to reach the sink node, and complete the synchronization between the cluster heads. The cluster head node collects the data in the cluster and forwards it to the sink node in multiple hops.

[0022] C. When multi-sensor cooperative perception of the target is required, the relevant nodes near the target enter the cooperative sensing state and exchange information on another channel. The nodes use data-centric routing to complete target positioning and tracking.

[0023] As a preferred mode of the present invention, the step A sp...

Abstract

The invention discloses a wireless sensor network (WSN) network architecture with cooperative sensing energy-efficient, which comprises the following steps that: A. clustering is made, that each node becomes a cluster head or a cluster member is confirmed; B. a tree topology reaching a sink node is formed among the cluster heads, the synchronism among the cluster heads is finished, and the cluster head nodes collect the data in the clusters and then makes multi-hop forwarding to the sink node; C. when a multi-sensor is needed to cooperatively sense a target, the related nodes near the target enter a cooperative sensing state and interact the information on the other channel, and a route with data as a center is used among the nodes to finish the positioning and the tracking of the target. The wireless sensor network (WSN) network architecture has the characteristics of whole data convergence, local cooperative sensing and data fusion of the wireless sensor network, can effectively decrease the energy consumption of the communication, can also assure the flexibility of the cooperative sensing, and is a wireless sensor network architecture with energy-efficient cooperative sensing.

Description

technical field [0001] The invention relates to a wireless sensor network, in particular to a wireless sensor network (WSN) network framework with efficient cooperative sensing energy. Background technique [0002] With the rapid development and maturity of sensor technology, wireless communication technology, embedded computing technology, and distributed information processing technology, micro-sensors and networks with perception, computing, and communication capabilities have begun to appear on a large scale. The wireless sensor network can collaboratively detect, track and collect information of various environments or monitoring objects in the network deployment area in real time, and carry out collaborative and fusion processing on these information to obtain more accurate conclusions, and then transmit them to users. It has broad application prospects in military, environmental monitoring, medical and health, industrial automation, public safety and so on. [0003] ...
