Dump energy, σ are preset energy proportion threshold value, and the value range of σ is) 1.25,1.35].
The present embodiment set initial distance threshold asEnsured sensor node directly with convergence
Node communication.The present embodiment further provides the energy condition for judging whether to need to raise distance threshold, realizes sensor
Switching of the node between direct communication mode and indirect communication mode, increases the flexibility of data communication；It is pre- every one
If period Δ T0, aggregation node only just carries out distance threshold when the energy datum of each sensor node meets the condition
Up-regulation avoids meaningless threshold distance up-regulation bring energy consumption.
In the present embodiment, energy condition has screened out maximum residual energy when calculating the average residual energy of sensor node
The case where with least residue energy, so that more accurate to the calculating of the average residual energy；The energy condition saves convergence
Point is lower than one relative to the average residual energy of the sensor node of distant place in the average residual energy of the sensor node of attachment
When certainty ratio, distance threshold is increased in time, the task of data forwarding is undertaken to promote more sensor nodes, to reduce
Originally the pressure with the sensor node of aggregation node direct communication in terms of forwarding data is further conducive to avoid energy empty
The phenomenon that hole, improves the stability of wireless sensor network operation.
In one embodiment, aggregation node according to the following formula raises current distance threshold:
In formula, HT' for up-regulation after distance threshold, HTFor up-regulation before distance threshold,For to aggregation node away from
Average value with a distance from all the sensors node to aggregation node more than current distance threshold,To be saved to convergence
The distance of point be less than all the sensors node of current distance threshold to aggregation node distance average value；
Work as HT' reach it is preset apart from the upper limit or up-regulation number reach preset frequency threshold value when, stop distance threshold value
Up-regulation.
The present embodiment proposes the up-regulation formula of distance threshold, the formula with to the distance of aggregation node be more than it is current away from
Increase part of the average value with a distance from all the sensors node to aggregation node as distance threshold from threshold value, and with opposite
Dump energy increases the influence factor of part than the comparison result with energy proportion threshold value as influence distance threshold, so that distance
The increase of threshold value can change with the variation of the dump energy of sensor node, the distance threshold after advantageously allowing up-regulation
More suitable current network condition, ensures that a certain number of neighbours' sensor nodes are added to and aggregation node direct communication
Sensor node set.
In one embodiment, when initial, sensor node is in the proximity sense closer apart from aggregation node relative to it
In device node, select apart from nearest sensor node as next-hop node；Next-hop node according to setting period Δ T1
The current remaining and available cache memory size of time recording oneself, since second period, next-hop node judges whether
Meet following early-warning conditions, if satisfied, next-hop node sends feedback data to the sensor node, which is received
After feedback data, relative to it in the closer proximity sensor node of aggregation node, selection with the next-hop node away from
From nearest sensor node as new next-hop:
In formula, Pw(u) indicate that next-hop node w currently judges the current remaining of periodic recording u-th of period,
Pw(u-1) current remaining of the expression next-hop node w in the u-1 periodic recording, u >=2,To judge value function, whenWhen, WhenWhen,Sw(u) for next-hop node w u-th period be currently judge periodic recording can
With the size of caching, SwIt (u-1) is size of the next-hop node w in the available cache memory of the u-1 periodic recording, SminFor setting
Minimum cache threshold.
The feedback early warning mechanism of next-hop node is present embodiments provided, wherein it is every innovatively to set next-hop node
The early-warning conditions of own situation are judged every a cycle Δ T.It is in the prior art generally only the current residual in next-hop node
Reselecting for next-hop node is carried out when energy is lower than minimum energy, and in the present embodiment, which considers energy consumption
The case where rate and available cache memory, so that having more robustness and accuracy to the determination of the actual conditions of next-hop node.
In the present embodiment, which sends early warning to a jump set sensor node thereon when meeting the early-warning conditions
Message promotes the sensor node for receiving the early warning information to reselect next-hop node, advantageously reduce next-hop node because
For energy consumption is too fast or following caching is insufficient and the probability of packet loss, and then improve the reliability and efficiency of data communication.

Mode is communicated with the aggregation node, and the direct communication is that the data of acquisition are directly sent to the convergence by sensor node
Node, the data of acquisition are sent to next-hop node for sensor node by the indirect communication, to be forwarded by next-hop node
The data of the acquisition, until the data of the acquisition are sent to aggregation node；
Sensor node is saved according to the mode and the convergence of distance selection direct communication or indirect communication to aggregation node
Point communication, specifically:
(1) distance for setting nearest apart from aggregation node, secondary close sensor node to aggregation node is respectively Hmin0、Hmin1, setting
Initial distance threshold isWhen initial, the distance of sensor node to aggregation node is less thanWhen, it selects the mode of direct communication to communicate with the aggregation node, is more thanWhen, then it selects
The mode for selecting indirect communication is communicated with the aggregation node；
(2) every a preset period Δ T0, aggregation node obtains each sensing by the data interaction with each sensor node
The energy datum and position data of device node, and judged whether to meet following energy bar according to the energy datum and position data
Part if satisfied, aggregation node raises current distance threshold, and the distance threshold of up-regulation is broadcasted to each sensor section
Point:
In formula, i indicates that the distance of aggregation node, i-th of sensor node for being no more than current distance threshold, j are indicated to remittance
The distance of poly- node is more than j-th of sensor node of current distance threshold, L1Work as to be no more than to the distance of aggregation node
The sensor node quantity of preceding distance threshold, L2For the sensor section for the distance of aggregation node being more than current distance threshold
Point quantity, PiFor the current remaining of i-th of sensor node, PjFor the current residual of j-th of sensor node
Energy, σ are preset energy proportion threshold value, and the value range of σ is [1.25,1.35].
6. a kind of data communication equipment according to claim 5, characterized in that the control module is also used to:
The access request for responding local device controls the communication module and provides the operation interface of the data saved to the local
Equipment；
Respond operation of the local device based on the operation interface.
7. a kind of data communication equipment according to claim 5, characterized in that described device further includes alarm module, institute
Alarm module is stated for the display alarm information when received data are abnormal.
8. a kind of data communication system, characterized in that the system comprises remote data processing device, wireless sensor network are logical
Believe that subsystem and local device, the remote data processing device, network communication of wireless sensor subsystem and local device are used
In execution method according to any of claims 1-4.
