In one embodiment, when netinit, sensor node receives the broadcast message of aggregation node, passes through broadcast
Information carries out network flood, and sensor node adds all neighbor nodes to the neighbor table of itself, wherein neighbor node for positioned at
Other sensors node in sensor node communication range；In pavement humidity data transfer phase, sensor node and convergence
The distance of node be single-hop apart from when, the pavement humidity data of acquisition are directly sent to aggregation node, sensor node and are converged
The distance of poly- node be not single-hop apart from when, the pavement humidity data of acquisition are sent to by sensor node by way of multi-hop
Aggregation node.
It in one embodiment, is not that the sensor node of single-hop distance determines next-hop section at a distance from aggregation node
It is specific to execute when point:
(1) after sensor node receives the next-hop node confirmation message that aggregation node is periodically sent, when calculating waiting
Between:
In formula, TiFor the waiting time that sensor node i is calculated, i=1 ..., N, N is the number of network inner sensor node
Amount, TminAnd TmaxIt is two time parameters being set in advance, respectively minimum latency, maximum latency, Ei、EioRespectively
Dump energy, primary power for sensor node i, D (i, sink) are distance of the sensor node i to aggregation node, RiFor
The communication distance of sensor node i；λ1、λ2For the weight coefficient of setting, meet 0 < λ1<λ2≤ 1 and λ1+λ2=1；
(2) any sensor node i waits TiAfterwards, the other sensors node into communication range sends election contest message；
It (3) is not the sensor node of single-hop distance at a distance from aggregation node by receive first election contest message institute
Corresponding neighbor node is as next-hop node.
Wherein, when each sensor node receives the next-hop node confirmation message of aggregation node transmission again, with remittance
The distance of poly- node is not that the sensor node of single-hop distance will redefine next-hop node.Pass through the regular of next-hop node
Selection is conducive to the energy consumption of balanced each sensor node, the life cycle of prolonging wireless sensor network.
The present embodiment proposes a kind of new Routing Protocol, is not the sensor section of single-hop distance at a distance from aggregation node
Point selects next-hop node according to the Routing Protocol, and the pavement humidity data of acquisition are sent to the next-hop node, wherein
By the design of waiting time, the waiting time of neighbor node can be controlled in a reasonable range, and can made
Dump energy is more and have the shorter waiting time apart from the closer neighbor node of aggregation node, thus with bigger general
Rate serves as the next-hop node of sensor node, to improve the reliability of pavement humidity data multi-hop transmission, thus for municipal road
The novel to maintain equipment of road construction carries out spray control and provides Data safeguard, improves the accuracy of spray control.
The present embodiment by voluntarily calculating the waiting time by neighbor node so that be omitted between sensor node position,
The information exchange of energy information, communication radius improves the efficiency of determining next-hop node, saves the energy of sensor node
Amount.
In one embodiment, next-hop node determines whether that its corresponding upper hop senses according to current remaining
Device node sends feedback message, receives the upper hop sensor node of the feedback message, temporarily selects in neighbor table current
The maximum neighbor node of dump energy is as next-hop node.
In one embodiment, next-hop node determines whether that its corresponding upper hop passes according to current remaining
Sensor node sends feedback message, comprising: when the current remaining of next-hop node meets early-warning conditions, next-hop node
Feedback message is sent to its corresponding upper hop sensor node, wherein the early-warning conditions are as follows:
In formula, EijFor the current remaining of the next-hop node j of sensor node i, Ejk0For the kth of next-hop node j
The current remaining of a neighbor node, njFor the neighbor node quantity of next-hop node j, EminFor preset energy lower limit value.
The present embodiment innovatively sets the mechanism of the spontaneous pause relay task based on early-warning conditions, which makes
Next-hop node is sent instead when its current remaining meets early-warning conditions to its corresponding upper hop sensor node immediately
Message is presented, and then upper hop sensor node temporarily reselects the maximum neighbours of current remaining based on the feedback message
Node is as next-hop node.The present embodiment can be avoided the next-hop node for undertaking relay task because the reduction of energy is quickly lost
Effect, is conducive to further increase the reliability that pavement humidity data are transmitted to aggregation node, thus for the new of municipal road construction
Type to maintain equipment carries out spray control and provides Data safeguard, improves the accuracy and stability of spray control.
In one embodiment, next-hop node determines whether that its corresponding upper hop passes according to current remaining
Sensor node sends feedback message, comprising: and next-hop node periodically calculates its communication distance threshold value according to current remaining, when
When the communication distance threshold value of calculating is less than it at a distance from upper hop sensor node, next-hop node upper hop sensor section
Point sends feedback message, wherein the calculation formula of setting communication distance threshold value are as follows:
In formula, Gi(t) the communication distance threshold value calculated for the next-hop node j of sensor node i t-th of period,For the adjustable maximum communication distance of sensor node i,For the adjustable minimal communications distance of sensor node i,
EiFor the current remaining of sensor node i, Ei0For the primary power of sensor node i, b is preset regulatory factor, b
Value range be [0.9,0.95].
Next-hop node periodically calculates its communication distance threshold value according to current remaining in the present embodiment, when leading to for calculating
When communication distance threshold value is less than it at a distance from upper hop sensor node, next-hop node upper hop sensor node sends anti-
Feedforward information, so that upper hop sensor node reselects next-hop node, wherein according to the current residual energy of next-hop node
Amount sets the setting formula of communication distance threshold value.The present embodiment is by allowing the lower next-hop node of energy to avoid continuing to undertake
The task of relay forwarding advantageously reduces the rate of next-hop node consumption energy, avoids next-hop node rapid failure, effectively
The duty cycle of next-hop node is extended, so that the novel to maintain equipment progress spray control for municipal road construction provides number
According to guarantee, the stability of spray control is improved.
Second aspect of the present invention embodiment additionally provides a kind of municipal road construction maintenance system, which includes institute as above
