The time of information,For the sensor node V set by aggregation nodeαThe theoretical time of aggregation node beacon message is received, δ is
The sensor node standard failure probability of setting；To judge value function, whenWhen,WhenWhen,
The present embodiment proposes a kind of new cluster head election contest mechanism, and in the mechanism, network inner sensor node is initially to set
The probability set becomes candidate cluster head, then broadcasted with maximum power oneself be cluster head message, if being received in transmitting radius another
The message of the candidate cluster head broadcast of an outer weights bigger, then abandon the competition of cluster head, otherwise oneself becomes cluster head.The prior art
In carry out candidate cluster head competition when, usual means be directly using the maximum candidate cluster head of current remaining as cluster
Head, and the present embodiment carries out the competition of candidate cluster head by weights size, and correspondingly define the calculation formula of weights.The meter
The energy and the factor in terms of received signal strength that formula has considered sensor node are calculated, and creatively considers sensing
The failure rate of device node.
Relative to directly in such a way that the maximum candidate cluster head of current remaining is as cluster head, the present embodiment produces
Unexpected effect：Integration capability more preferably cluster head can be chosen, to improve the stability of clustering topology, extend
Water monitoring data acquires and the work period of transmission.

The list is simultaneously sent to aggregation node by node listing；Aggregation node acquires easy malfunctioning node according to easy malfunctioning node list
Water monitoring data carries out abnormality detection, and determines exception water quality monitoring data and is sent to monitoring center after marking.
The present embodiment retransmits after the exception water quality monitoring data that detected are marked to monitoring center, convenient for prison
Measured center can be directly obtained exception water quality monitoring data, and then targetedly divide exception water quality monitoring data
Analysis.Present embodiment enhances the robustness of water monitoring data analysis, improve the efficiency that wireless sensor network resource uses.
Exception water quality monitoring data include error pattern water monitoring data and event mode water monitoring data, wherein error pattern
Water monitoring data refers to that water monitoring data is cannot to reflect the time of day of monitoring object and deviate considerably from pre-defined
Normal water monitoring data, and event mode water monitoring data refers to water monitoring data and pre-defined normal water quality
Monitoring data are inconsistent, but reflect the variable condition of monitoring object.
When being detected to exception water quality monitoring data, customary means in the prior art is to all the sensors node
The exception water quality monitoring data of acquisition are all detected, this undoubtedly increases the burden of aggregation node.The present embodiment is true by cluster head
Determine the easy malfunctioning node in cluster and inform aggregation node, and then is directed to the water quality monitoring number of easy malfunctioning node acquisition by aggregation node
According to carrying out abnormality detection, the burden of aggregation node is greatly reduced, energy is saved.
Wherein, the cluster head determines the easy malfunctioning node in cluster, specifically includes：
