In one embodiment, the communication distance of each sensor node is preset, when netinit, sensor section
Point is divided into multiple clusters by clustering route protocol, and each cluster includes a cluster head and multiple sensor nodes；Cluster head collects cluster
The high tower class building structure health data of interior each sensor node acquisition is simultaneously sent to aggregation node, specifically includes: cluster when initial
Head obtains neighbours' cluster head information by the information exchange with other cluster heads, and chooses a neighbour according to neighbours' cluster head information
Cluster head is occupied as relay node；In the high tower class building structure health data transmitting stage, cluster head is calculated according to self-energy and is sent
Distance is simultaneously regularly updated, and when the distance of cluster head to aggregation node is less than current transmission range, cluster head will directly be received
The high tower class building structure health data of collection is sent to aggregation node, when the distance of cluster head to aggregation node is more than current transmission
Apart from when, the high tower class building structure health data of collection is directly sent to selected relay node by cluster head,
Wherein, the calculation formula of the transmission range are as follows:
In formula, qIFor the transmission range of cluster head I, PIFor the current remaining of cluster head I, PI0For the primary power of cluster head I,

The routing mode selection of class building structure health data gives preferable measurement standard, the i.e. distance when cluster head to aggregation node
When being less than current transmission range, the high tower class building structure health data of collection is directly sent to aggregation node by cluster head,
When the distance of cluster head to aggregation node is more than current transmission range, cluster head is directly by the high tower class building structure health of collection
Data are sent to selected relay node.Cluster head is based on transmission range and selects suitable routing mode, advantageously reduces cluster head
The energy consumption for sending high tower class building structure health data, avoids cluster head from failing because energy rapidly depletes, and ensures wireless pass
The stability routed in sensor network.
Preferably, the clustering route protocol is the Routing Protocol based on LEACH.
It is described that neighbours' cluster head conduct is chosen according to neighbours' cluster head information in a kind of mode that can be realized
Relay node, comprising:
(1) cluster head will meet neighbours' cluster heads of alternative conditions alternately relay node, construct alternative relay node collection:
(2) cluster head concentrates the alternative relay node of selected distance recently as relay node in alternative relay node；
The alternative conditions are as follows:
In formula, ZIJIndicate cluster head I to the degree of belief of its neighbours' cluster head J, when initial, degree of belief of the cluster head to each neighbours' cluster head
It is all 1；ZIlIndicate degree of belief of the cluster head I to its first of neighbours' cluster head, NIFor neighbours' cluster head quantity of cluster head I, q (I, O) is cluster
Head I is to the distance of aggregation node, and q (J, O) is distance of the neighbours' cluster head J to aggregation node, and f [q (I, O)-q (J, O)] is
Judge value function, as q (I, O)-q (J, O)>=0, f [q (I, O)-q (J, O)]=1, as q (I, O)-q (J, O)<0, f [q
(I, O)-q (J, O)]=0.
The present embodiment, to the degree of belief situation of its each neighbours' cluster head, selects the neighbours closer apart from aggregation node based on cluster head
Cluster head alternately relay node, and further alternative relay node concentrate select the alternative relay node of distance recently as
Relay node, to be responsible for forwarding cluster head high tower class building structure health data collected.The present embodiment is correspondingly provided with standby
The selection alternative conditions of relay node are selected, a suitable standard is provided for the selection of alternative relay node, on the one hand guarantees
High tower class building structure health data will not be transmitted to the opposite direction of aggregation node, on the other hand ensure that high tower class is built
The reliability of structural health data forwarding.Pass through the alternative relay node conduct for concentrating selected distance nearest in alternative relay node
Relay node is conducive to the energy for saving the forwarding of high tower class building structure health data as much as possible, reduces energy consumption cost.
In one embodiment, cluster head obtains the energy information of relay node every period Δ t, works as relay node
Current remaining be lower than preset energy lower limit when, cluster head by the relay node from alternative relay node concentrate reject, and
Alternative relay node collection is updated, alternative relay node in the updated concentrates the alternative relay node for selecting distance nearest as new
Relay node.
The present embodiment carries out the real-time update of relay node, is conducive to the energy consumption of balanced each cluster head.
It is in one embodiment, described to update alternative relay node collection, comprising:
(1) cluster head updates its degree of belief that each alternative relay node is concentrated to current alternative relay node:
In formula, ZIS(y+1) degree of belief to its alternative relay node S that cluster head I is updated at the y+1 times, Z are indicatedIS(y)
For the degree of belief to its alternative relay node S that cluster head I is updated at the y times, PISFor the current residual of the alternative relay node S
Energy, PISOFor the primary power of the alternative relay node S, RISFor the high tower in the cache list of the alternative relay node S
Class building structure health data packet quantity, PZFor energy consumed by one high tower class building structure health data packet of preset forwarding
Amount, PminFor preset energy lower limit, e-kFor degree of belief decay factor, e is Euler's constant, k ∈ (0,0.2]；
(2) cluster head judges that current alternative relay node concentrates each alternative relay node to be whether according to the degree of belief of update
Meet the alternative conditions, the alternative relay node for being unsatisfactory for the alternative conditions is picked from current alternative relay node concentration
It removes, completes the update of alternative relay node collection.
The present embodiment innovatively sets the more new formula of degree of belief, and the more new formula is according to energy and forwarding cache
The Energy Expenditure Levels that data may cause judge degree of belief of the alternative relay node relative to cluster head, and the letter based on update
Appoint degree to rejudge current alternative relay node and concentrate whether each alternative relay node meets alternative conditions, to screen out improper
Alternative relay node so that the selection of alternative relay node has certain robustness, be conducive to improve relative energy it is sufficient,
The few neighbours' cluster head of high tower class building structure health data forwarding task amount successfully serves as the probability of relay node, thus further
The energy consumption of each cluster head in equalising network, the service life of prolonging wireless sensor network.
