The convenience and safety of management.
In one embodiment, it needs to affix one's name to multiple sensor nodes inside the monitoring region of setting according to actual monitoring
Afterwards, suitable sensor node is increased according to the deployment scenario of sensor node, including：
(1) whether each sensor node that detection has been disposed meets following density conditions, will not meet the biography of density conditions
Sensor node is considered as low-density node：
In formula, BiFor the node degree of sensor node i, i.e. the neighbor node number of sensor node i, wherein being defined on biography
Other sensors node in sensor node communication range is its neighbor node；S is the sensor node disposed in network
Number, YjFor the communication distance for j-th of the sensor node disposed in network, U is the area in the monitoring region, and f is default
Regulatory factor, the value range of f is [0.6,0.8]；
(2) new sensor node is disposed in the communication zone of each low-density node, specially：To any low-density section
Point k, if its communication zone is Ψk, calculate the sensing region lap Ω of all neighbor nodes of low-density node kk,
Ψk-ΩkRegion in one new sensor node of random placement；
(3) (1), (2) are repeated, until low-density node is not present.
The present embodiment increases suitable sensor node according to the deployment scenario of sensor node, wherein innovatively setting
Density conditions, are considered as low-density node for the sensor node for not meeting density conditions, and in low-density node communication zone
It is interior to increase new sensor node, be conducive to improve sensor node distributing homogeneity.
In addition, the present embodiment avoids all neighbor nodes of low-density node when increasing new sensor node
Sensing region lap, the overlapping region for advantageously allowing the sensor node newly increased and its neighbor node is small as far as possible, into
One step improves network coverage quality.
In a kind of mode that can be realized, sensor node carries out sub-clustering according to node density, therefrom determines cluster head, general
Logical member node, isolated node；The stage is transmitted in environmental data, the environmental data of acquisition is sent to cluster by rank and file's node
Head, the environmental data of acquisition is sent to aggregation node module 2 by cluster head；The environmental data that isolated node acquires itself
It is sent to aggregation node module 2 by directly transmitting mode or multi-hop transmission mode, including：Isolated node and aggregation node mould
The distance of block 2 is no more than preset apart from lower limit XminWhen, the environmental data of acquisition is directly transferred to aggregation node by isolated node
Module 2；Isolated node is more than preset apart from lower limit X at a distance from aggregation node module 2minWhen, isolated node is by the ring of acquisition
Border data are sent to aggregation node module 2 by multi-hop transmission mode.
The present embodiment sets isolated node to the routing mechanism of aggregation node module 2.
In a kind of mode that can be realized, sensor node carries out sub-clustering according to node density, including：
(1) aggregation node module 2 sends sub-clustering instruction to each sensor node of network, and each sensor node receives sub-clustering
After instruction, the density factor of oneself is calculated, if Ci>=1, then sensor node i becomes alternate node, and broadcasts to neighbor node
Cluster head campaigns for message, concurrently sets for the first time limit：
In formula, CiIndicate the density factor of sensor node i；
(2) alternative to save if alternate node receives the cluster head election contest message of remaining alternate node broadcast within the first time limit
The current remaining of itself is compared by point with the current remaining of remaining alternate node, and current remaining is most
Big alternate node will become cluster head, remaining alternate node abandons the election contest of cluster head；If alternate node does not have within the first time limit
The cluster head election contest message for receiving the broadcast of remaining alternate node, then become cluster head；
(3) cluster head broadcasts cluster message to its neighbor node, and sensor node is when setting second after receiving cluster message
Limit；
If sensor node does not receive remaining cluster message within the second time limit, sensor node is saved as rank and file
The cluster head for being sent to it cluster message is added in point；
If sensor node receives remaining cluster message within the second time limit, sensor node as rank and file's node,
In the multiple cluster heads for being sent to it cluster message, select apart from nearest addition cluster；
If sensor node does not receive cluster message always, which becomes isolated node.
The present embodiment innovatively carries out sub-clustering to sensor node according to node density, wherein thick for sensor node
Close region chooses corresponding cluster head and carries out sub-clustering, and for sensor node sparse region, then sub-clustering mode is not used, and
Isolated node is directly determined, the present embodiment enables to the topological structure of wireless sensor network more flexible, has adaptive
Property.By collecting the environmental data of rank and file's node acquisition by cluster head, advantageously reducing energy in sensor node dense Region
Amount consumption, and sub-clustering mode is not used in sensor node sparse region, be conducive to avoid meaningless environmental data collection mistake
Journey further saves cost of energy.
In a kind of mode that can be realized, the environmental data of acquisition is sent to by isolated node by multi-hop transmission mode
When aggregation node module 2, need to select next-hop node.It is specific to execute when isolated node selects next-hop node：
(1) isolated node determines remaining isolated node and cluster head within the scope of self communication, remaining determining is isolated
Node and cluster head establish candidate forward node list as candidate forward node；
(2) Superiority Value of each candidate forward node in candidate forward node list is calculated：
In formula, VαβFor the β candidate forward node of isolated node α, XαβFor isolated node α and its β candidate forwarding
The distance of node, XβoDistance for described the β candidate forward node to aggregation node module 2, HβIt is described the β candidate turn
Send out the current remaining of node, H1Energy consumption interior per unit time for sensor node for communication, H2For sensor
The energy consumption interior per unit time that node is used to perceive and calculate, H1、H2Value be fixed setting value, w1、w2For preset weight
Coefficient；
(3) the maximum candidate forward node of selective advantage value is as next-hop node, and isolated node is by the environment number of acquisition
According to being sent to the next-hop node.
In the present embodiment, remaining isolated node of isolated node when selecting next-hop node, within the scope of self communication
And in cluster head, selective advantage value is maximum to be used as next-hop node.The present embodiment can save environmental data through excessive as far as possible
The cost of energy of aggregation node module 2 is transported in jump set, and is beneficial to balance the energy consumption of each sensor node of network.
