In one embodiment, sensor node model use Boolean sense model, sensor node the perception radius isomery,
The perception radius of any sensor node is in [Rmin,Rmax] in range, wherein RmaxAnd RminIt is divided into sensor node the perception radius
Bound；Sensor node is affixed one's name to inside the monitoring region of setting according to actual demand, and when deployment is arranged arbitrary neighborhood two
The distance D (i, j) of sensor node i, j meet:
In formula, RiFor the perception radius of sensor node i, RjFor the perception radius of sensor node j, RkTo be pressed in network
According to the perception radius of k-th of sensor node of actual demand deployment, n is the sensor section disposed in network according to actual demand
Point quantity, Ω are the volume in the monitoring region.
The present embodiment is by the distance between setting two sensor nodes of arbitrary neighborhood range, to control two adjacent biographies
The degree of overlapping of sensing range between sensor node, enables to the overlapping of the sensing range between two neighboring sensor node
In relatively reasonable level, it is also beneficial to avoid can not achieve higher covering between sensor node due to hypertelorism
Rate.
Further, after affixing one's name to sensor node inside the monitoring region of setting according to actual demand, by the monitoring of setting
Region division is adjusted at multiple sections, and to the sensor node quantity of each section, comprising:
(1) determine that each sensor node of deployment to the distance of aggregation node, sets the quantity ρ of piece Division:
In formula, DmaxFor maximum distance of the sensor node to aggregation node of deployment, DminFor the sensor node of deployment
To the minimum range of aggregation node, Dmax*1For time big distance of the sensor node to aggregation node of deployment, Dmin*1For deployment
For sensor node to the secondary small distance of aggregation node, η is the interval between the monitoring region adjacent sheet area of setting；
(2) successively label is carried out to each section according to the sequence that monitoring dynamics demand grows from weak to strong, so that monitoring dynamics needs
Ask most weak section marked as 1, and monitor the strongest section of dynamics demand marked as ρ, monitor each section root in region
Different power levels is assigned according to the size of label, wherein the power level of the section marked as m are as follows:
Qm=em*ρ
In formula, QmIndicate the power level of the section marked as m, e is natural constant；
(3) sensor node quantity that the section should be distributed is calculated according to the power level of section:

Power level；
(4) the real sensor node deployment quantity for counting each section, according to the sequence that section label is ascending, to each
Section successively carries out quantity detection and adjustment, specifically: as the real sensor node deployment quantity Φ in sectiona' be greater than and answer
The sensor node quantity Φ of the distributionaWhen, select label maximum as movement in two sections adjacent with the section
Destination, by the closer Φ of mobile destination described in distance in the sectiona′-ΦaA sensor node is moved to the mobile mesh
Ground, and update the real sensor node deployment quantity of mobile destination, next section detected.
After the present embodiment affixes one's name to sensor node inside the monitoring region of setting according to actual demand, by the monitoring section of setting
Domain is divided into multiple sections, and is adjusted to the sensor node quantity of each section.The present embodiment proposes specific sensing
Device number of nodes Regulation mechanism, the mechanism are the corresponding power level of each section setting according to monitoring dynamics demand, and according to power level
The sensor node quantity that the section should be distributed is calculated, it is practical by calculated sensor node quantity and sensor node
Deployment quantity is compared, it is determined whether the sensor node quantity in adjustment section.The present embodiment makes sensor node phase
To the higher region of monitoring dynamics demand is concentrated on, other area sensor Node distributions are less, so as to further increase
The network coverage in relatively important monitoring region optimizes network topology relative to the mode of random placement sensor node
Structure, and then promote the Monitoring Performance of wireless sensor network.
In one embodiment, when netinit, sensor node passes through the information exchange with other sensors node
Determine neighbor node, wherein neighbor node is remaining sensor node in sensor node communication range；Aggregation node
Xiang Yuqi distance is less than setting apart from lower limit DminSensor node send suspend mode instruction message, receive suspend mode instruction disappear
The sensor node of breath carries out compared with apart from nearest neighbor node, if sensor node is relative to apart from nearest neighbour
Node is occupied closer to aggregation node, then sends dormancy instruction to apart from nearest neighbor node, is saved with enabling apart from nearest neighbours
Point enters dormant state, otherwise enables and oneself enters dormant state.
In one embodiment, aggregation node by with its distance be less than setting apart from lower limit DminSensor node and
The nearest neighbor node of respective distances is as neighboring node, and the energy of each sensor node disappears in the regular collection network of aggregation node
Breath, and whether energy condition is met according to the neighboring node that energy message detects non-suspend mode, the neighbour for meeting energy condition is saved
Point sends replacement notice；The neighboring node for receiving replacement notice wakes up it apart from nearest neighbor node, and then oneself enters
Dormant state.
Wherein, the energy condition is set are as follows:
In formula, ElFor the current remaining of neighboring node l, EkFor the current residual energy of k-th of sensor node in network
Amount, n are the sensor node quantity disposed in network.
Sensor node near aggregation node not only transmits the concentration of toxic gases data of oneself acquisition, also to relay and turn
The concentration of toxic gases data of other sensors node are sent out, therefore the sensor node near aggregation node is compared far from convergence
The sensor node of node will send more concentration of toxic gases data, so wireless sensor network is near aggregation node
It is easy to produce Energy volution.Based on this problem, the present embodiment defines neighboring node and energy condition, and makes neighboring node
When energy is unsatisfactory for the energy condition of setting, it is waken up apart from nearest neighbor node, then oneself enters dormant state.This
The energy that embodiment can be avoided the neighbouring sensor node rapidly depletes, so that above-mentioned Energy volution phenomenon is effectively avoided,
The life span of prolonging wireless sensor network.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
