In one embodiment, base station to sensor node carry out sub-clustering, to by sensor node be divided into cluster head and at Member's monitoring node, member's monitoring node is for acquiring indoor environment perception data and being sent to indoor environment perception data affiliated The cluster head of cluster;Cluster head is used to receive and process the indoor environment perception data of cluster member transmission, is additionally operable to that treated is indoor Environment sensing data are sent to base station.
In one embodiment, base station carries out sub-clustering to sensor node, specifically includes:
(1) base station determines N number of alternative cluster head from all the sensors node;
(2) alternative cluster head screening is carried out, specifically, for alternative cluster head α, β of any two, if meeting distance condition, The smaller alternative cluster head of wherein dump energy is reverted into ordinary node;
(3) using be still alternative cluster head sensor node as cluster head, and according to existing cluster head be finally completed cluster draw Point, remaining sensor node k is belonged to it apart from shortest cluster head, becomes member's monitoring node;
Wherein, distance condition is:
In formula, H (α, β) is the distance between alternative cluster head α and β, and H (α, sink) is distances of the alternative cluster head α to base station, H (β, sink) is alternative cluster head β to the distance of base station, HmaxFor the distance of the sensor node farthest apart from base station to base station, HminFor the distance of the sensor node nearest apart from base station to base station, r is the regulation and control coefficient of setting, LmaxFor the cluster radius of setting Maximum occurrences, min [] expressions are minimized function.
Sub-clustering is carried out based on particle region optimization algorithm on multiple populations, it is likely that will produce the intensive situation of cluster head, this implementation Example screens alternative cluster head by distance condition, effectively prevents the occurrence of cluster head is overstocked so that wireless sensor The sub-clustering topology of network is more reasonable.In addition, the alternative cluster head that the present embodiment selects dump energy more always serve as it is final Cluster head, this is more advantageous to the equilibrium of network energy, so as to effectively extend the work of indoor environment perception data acquisition and transmission Make the period, improves the stability of smart home environment regulating system operation.
In one embodiment, base station determines N number of alternative cluster head from all the sensors node, specifically includes:
(1) indoor environment monitoring area is randomly divided into N number of subregion;
(2) to each sensor node, calculating it becomes the preferred value of cluster head;
(3) for every sub-regions, by the maximum sensor node of preferred value alternately cluster head.
Indoor environment monitoring area is randomly divided into multiple subregions by the present embodiment, and is selected alternatively from all subregion Cluster head, so as to control the number of cluster head, the corresponding scale for controlling cluster.
Wherein, if DiIndicate that sensor node i becomes the preferred value of cluster head, DiCalculation formula be:
In formula, DiIndicate that sensor node i becomes the preferred value of cluster head, LiFor the communication distance of sensor node i, H (i, J) at a distance between the neighbor node being located in same subregion with its j-th for sensor node i, BiFor sensor node i's Neighbor node number in same subregion, the wherein neighbor node of sensor node i are positioned at the logical of sensor node i Believe the sensor node in range;
H (i, sink) is sensor node i to the distance of base station, PiFor the current remaining of sensor node i, 3jFor J-th of neighbor node current remaining of sensor node i, e1For distance weighting coefficient, e2For energy weight coefficient.
The present embodiment is when designing preferred value calculation formula, it is contemplated that node spacing, distance and capacity factor to base station, The compactedness for being conducive to improve sub-clustering makes the region closer apart from base station generate more cluster heads, and make dump energy compared with There is big sensor node the probability of bigger to become cluster head, is beneficial to balanced sensor node energy consumption, extends the life of network Period improves the reliability of indoor environment perception data acquisition and transmission.
In one embodiment, after base station carries out sub-clustering to sensor node, sub-clustering is no longer carried out.The present embodiment uses cluster Head continuously serves as mechanism, it is possible to reduce chooses the energy that cluster head is consumed in turn.
Base station is periodically detected cluster head, if the current remaining of cluster head is less than member's monitoring node energy in its cluster When mean value, select the maximum member's monitoring node of weights as new cluster head.
Wherein, the calculation formula of weights is:
In formula, WxIndicate the weights of member's monitoring node x, PxFor the current remaining of member's monitoring node x,For at Member's monitoring node average energy value of cluster, L where member's monitoring node xxFor the communication distance of member's monitoring node x, H (x, y) is Distances of member's monitoring node x to its cluster head y;71、72For weight coefficient.
Usually just cluster head is replaced when the current remaining of cluster head is less than minimum energy value in the related technology, so And there is no the energy variation situations for considering its cluster inner sensor node for this substitute mode.The present embodiment is in the current of cluster head Dump energy carries out cluster head replacement when being less than member's monitoring node average energy value in its cluster so that the replacement of cluster head is more flexible Property.
In addition, according to the calculation formula of weights it is found that energy is higher, closer apart from cluster head member's monitoring node has more Big weights, the present embodiment carry out cluster head when the current remaining of cluster head is less than member's monitoring node average energy value in its cluster It replaces, selects the maximum member's monitoring node of weights to replace former cluster head, be conducive to equalising network energy, it is ensured that newly appointed cluster head energy Enough complete the task that indoor environment perception data is collected.
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 being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention Matter and range.
