Aquaculture field monitors subregion, and to each sensor node broadcasts message, each sensor node is confirmed belonging to itself
Aquaculture field monitors the sensor node list that subregion and aquaculture field monitoring subregion include；Belong to same
Sensor node in individual aquaculture field monitoring subregion is campaigned for by cluster head determines leader cluster node, remaining sensor section
Point is used in cluster where receiving and handling as the environmental data collecting node in cluster where the leader cluster node, wherein leader cluster node
The aquaculture field environmental data of each environmental data collecting node collection, and by the aquaculture field environmental data after processing
It is transferred to next-hop node or base-station node.
In one embodiment, the sensor node belonged in same aquaculture field monitoring subregion passes through cluster head
Election contest determines leader cluster node, specifically includes：
(1) when every wheel cluster head election contest starts, each sensor for belonging in same aquaculture field monitoring subregion
Node calculates the random threshold value of epicycle according to the following formula：
In formula, TijIt is random to represent that j-th of sensor node in i-th of aquaculture field monitoring subregion calculates
Threshold value, rijMonitor the maximum communication radius of j-th of sensor node in subregion for i-th aquaculture field, D (ij,

The leader cluster node of subregion is monitored for affiliated aquaculture field, other alternate nodes are as conventional environment data acquisition node.
The present embodiment devises the leader cluster node election contest mechanism in aquaculture field monitoring subregion, and each aquatic products are supported
Grow field monitoring subregion and campaign for out a leader cluster node, ensure that leader cluster node can be in the deployment region of wireless sensor network 1
In be evenly distributed, so as to reduce the via net loss caused by the irrational distribution of cluster, in the election contest mechanism, first pass through random threshold value
Mode elect alternate node at random, then chosen in alternate node life cycle it is maximum be used as leader cluster node so that it is every
Individual sensor node has the opportunity to turn into leader cluster node, so as to the energy consumption of sensor node in average wireless sensor network 1, and
And cause neighbor node density it is big, apart from base-station node is near, the sensor node of life cycle length has higher probability to be elected as
Leader cluster node, so as to beneficial to the stability for improving aquaculture field environmental data collection.
In one embodiment, the calculation formula for defining the life cycle of sensor node is：
In formula, QijThe life cycle of j-th of sensor node in i-th of aquaculture field monitoring subregion is represented,
EijThe current remaining of j-th of sensor node in subregion is monitored for i-th of aquaculture field, μ is the biography of setting
Sensor node sends the energy expense of an aquaculture field environmental data bag, and v is that the sensor node of setting receives one
The energy expense of aquaculture field environmental data bag, NiThe sensing disposed in subregion is monitored for i-th of aquaculture field
Device node number, ξ are the unit distance energy loss of setting, and ik represents i-th of aquatic products in addition to j-th of sensor node
K-th of sensor node in plant's monitoring subregion, D (ij, ik) are that i-th of aquaculture field is monitored in subregion
The distance between j-th of sensor node and ik.
