Safety.
In a kind of mode that can be realized of above-described embodiment, each sensor node is divided into directly by the aggregation node
Communication node and indirect communication node are connect, in data transmission procedure, the indirect communication node is opposite in its communication range
In it in the closer sensor node of aggregation node, select nearest sensor node as next-hop, by the institute of acquisition
The heat transfer agent of monitoring position is sent to next-hop；And the heat transfer agent of acquisition is sent directly to the remittance by direct communication node
Poly- node；Wherein, described that each sensor node is divided into direct communication node and indirect communication node, comprising: according to sensing
The distance of device node to aggregation node determines each sensor node, when sensor node meets direct communication condition,
The sensor node is determined for direct communication node, if not satisfied, being determined as indirect communication node, and wide to each sensor node
Broadcast judgement information；
The direct communication condition are as follows:
In formula, LsaIndicate aggregation node at a distance from a-th of sensor node,Indicate aggregation node and distance most
The distance of close sensor node,Indicate aggregation node and the distance apart from secondary close sensor node,It indicates
Aggregation node and the distance apart from farthest sensor node, N are the sensor node quantity in network.
The present embodiment by the way that sensor node is divided into two kinds of node types of direct communication node and indirect communication node,
So that sensor node is communicated with aggregation node according to own type using different communication modes, improve sensor node and
The flexibility routed between aggregation node.Corresponding differentiation is creatively wherein proposed according to the deployment scenario of sensor node
Condition, it is ensured that have appropriate number of sensor node and aggregation node direct communication, ensure the collection of heat transfer agent.
In a kind of mode that can be realized, the aggregation node is every a preset period Δ T1, according to directly logical
The heat transfer agent that letter node and its neighbor node acquired within a upper period calculates the letter of direct communication node and its neighbor node
Difference degree is ceased, if information gap degree is greater than the difference degree threshold value of setting, the aggregation node records the direct communication
The insincere number of node adds 1, when the insincere number that aggregation node is accumulated to the direct communication node reaches preset number
When the upper limit, the aggregation node sends dormancy instruction to the direct communication node, and the direct communication node is promoted to enter suspend mode
State, the calculation formula of the information gap degree are as follows:
In formula, CI(t) indicate direct communication node I during t-th of period with the information gap degree of its neighbor node,
xI(a) heat transfer agent acquired for direct communication node I at a moment,Neighbor node for direct communication node I exists
The average value for the heat transfer agent that a moment acquires, the neighbor node are the sensing in direct communication node I communication range
Device node.
When carrying out information collection using wireless sensor network technology, since there are finite energies, possibility for sensor node
The features such as failure, influencing vulnerable to environment be easy to cause the precision of collected information lower.For this problem, this implementation
The heat transfer agent of the heat transfer agent that example is periodically acquired direct communication node by aggregation node and its ambient sensors node into
Row compares, and carries out insincere number record to direct communication node when information gap degree is greater than certain threshold value, when being accumulated to
When the insincere number of the direct communication node reaches preset maximum number of times, suspend mode is carried out to the direct communication node.This reality
Acquisition and transmission that example is able to suppress incredible heat transfer agent are applied, the energy consumption of information transmission is reduced, avoids information collection precision
The sensor node of difference influences the precision of Global Information, improves the accuracy that heat transfer agent is collected.
