The change of water quality of network real-time monitoring water resources in lake, it can be ensured that the metropolitan water safety in periphery, and then realize good
Social benefit and economic benefit.
In a kind of mode that can be realized, each sensor node passes through exchange acquisition of information neighbor node mark and position
Information, wherein the other sensors node being defined in sensor node transmission range is its neighbor node；Sensor node is adopted
After collecting lake water quality parameter, the lake water quality parameter of acquisition is transferred to aggregation node, comprising:
(1) sensor node is no more than preset apart from lower limit L at a distance from aggregation nodeminWhen, sensor node is direct
The lake water quality parameter of acquisition is transferred to aggregation node；
(2) sensor node is more than preset apart from lower limit L at a distance from aggregation nodeminWhen, sensor node will acquire
Lake water quality parameter aggregation node is transferred to by way of multi-hop, specifically:
1) sensor node of acquisition lake water quality parameter is set as source node, and source node determines that it arrives the biography of aggregation node
Defeated total hop count k:
In formula, LI, oFor the distance of source node i to aggregation node, LA, oIt is saved for a-th of sensor node in network to convergence
The distance of point, Z are the sensor node quantity in network,For bracket function, expression pairIt is rounded；
2) source node generates data packet, and data packet includes the mark of the source node, lake water quality parameter packet and hop count meter
Number device, the initial value of the hop count device are the total hop count of transmission that source node determines, which includes source node
Lake water quality parameter collected；
3) source node randomly chooses destination node of the neighbor node as the jump in its neighbor node, by data packet
It is sent to the destination node of the jump；
4) after destination node receives data packet, the data packet is updated, comprising: by the value of the hop count device in data packet
Subtract one, and the lake water quality parameter of itself acquisition is stored in the lake water quality parameter packet in data packet；
5) it using destination node as the source node of next-hop, repeats 3), 4), until in the data packet that destination node receives
Hop count device value be 1；The destination node that the value of hop count device in the data packet received is 1, itself is acquired
Lake water quality parameter deposit data packet in lake water quality parameter packet after, by lake water quality parameter packet be sent directly to convergence section
Point.
The present embodiment proposes sensor node and the lake water quality parameter of acquisition is transferred to convergence by way of multi-hop
The routing mechanism of node, the routing mechanism determine the transmission of transmission lake water quality parameter according to the distance of source node to aggregation node
Total hop count, and determine based on the mode of random walk the destination node of next-hop.Lake water quality ginseng is carried out by the routing mechanism
Several multi-hop transmissions, it is simple and convenient, and the length of transmission path can be limited, avoid the mode because of random walk from leading to path
It is too long and bring meaningless energy consumption, save the data acquisition cost of lake water quality intelligent monitor system.
Wherein, if source node is no more than cooperation apart from lower limit L at a distance from the destination nodex-minWhen, source node directly will
Data packet is sent to the destination node of the jump；If source node is more than cooperation at a distance from the destination node apart from lower limit Lx-minWhen,
Source node more directly transmits the energy consumption of data packet mode and the energy consumption of cooperation transmission data packet mode, if directly transmitting data packet
The energy consumption of mode is minimum, and source node directly sends data packets to the destination node of the jump, otherwise uses cooperation transmission data packet
Mode sends data packets to the destination node of the jump.
In a kind of mode that can be realized, source node calculates each neighbour after obtaining neighbor node mark and location information
The weight of node is occupied, and each neighboring node list is ranked up according to the descending sequence of weight, building neighbor node column
Table；Source node sends data packets to the destination node of the jump using cooperation transmission data packet mode, specific to execute: source node to
Preceding 3 neighbor nodes broadcast collaboration message of neighboring node list, preceding 3 neighbor nodes receive after cooperation message to source node
Cooperation confirmation message is fed back, source node selects the neighbor node for feeding back cooperation confirmation message at first as cooperative node, by data
Packet is sent to the cooperative node, and the destination node of the jump is sent data packets to by the cooperative node；Wherein the calculating of weight is public
Formula are as follows:
In formula, dijFor the weight of j-th of neighbor node of source node i, QjFor the current residual of j-th of neighbor node
Energy, QminTo preset minimum energy value, LI, jAt a distance from j-th of neighbor node of source node i and its, e1For preset energy power
Repeated factor, e2For the preset distance weighting factor.
The present embodiment sets the weight computing formula of neighbor node, by the calculation formula it is found that dump energy is more, position
The bigger neighbor node of advantage is set with bigger weight.Source node in advance saves each neighbours according to the sequence of weight from big to small
Point is arranged, and avoids wasting time in the calculating of transmission lake water quality parametric step progress weight；In the present embodiment, source section
To preceding 3 neighbor nodes broadcast collaboration message of neighboring node list, which receives after cooperation message to source point
Node feeding back cooperation confirmation message, source node select the neighbor node for feeding back cooperation confirmation message at first as cooperative node, will
Data packet is sent to the cooperative node, can the cooperative node selected of effective guarantee be reliably completed cooperation transmission lake water quality parameter
Task, and relative to random selection cooperative node mode, be relatively beneficial to save cooperation transmission lake water quality parameter energy consumption.
In a kind of mode that can be realized, when source node sends data packets to the destination node of the jump, according to following
Formula calculates cooperation apart from lower limit Lx-min:
In formula, V is monitoring region area, and Z is the sensor node quantity in network, and S is the transmission radius of source node；
The present embodiment sets the specific transmission mechanism that source node transmits data packet to destination node, wherein source node is arrived
The distance of destination node is compared with cooperation apart from lower limit, and data are more directly transmitted when distance is higher than cooperation apart from lower limit
The energy consumption of packet mode and the energy consumption of cooperation transmission data packet mode, and the minimum transmission mode of selection energy consumption carries out data packet always
Transmission.The present embodiment can more ensure that data packet passes relative to by way of the progress data packet transmission of single transmission mode
Defeated reliability, and relative to only cooperation transmission mode carry out data packet transmission by way of, due to selecting energy consumption always most
Low transmission mode carries out the transmission of data packet, can further decrease the energy consumption of lake water quality parameter transmission；The present embodiment into
The calculation formula to cooperate apart from lower limit is given to one step, relative to the mode of subjectively preset threshold, is cooperated apart from lower limit
Determine more closing to reality situation.
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
