In one embodiment, cluster head passes through the transmission range that adjusts the transmission power of itself to adjust oneself；When initial
Cluster head judges whether itself to the distance of aggregation node is more than itself maximum transmission range, if being no more than, cluster head is by collection
Data are sent directly to aggregation node；If being more than, cluster head selects indirect mode that the data of collection are sent to aggregation node, institute
State indirect mode are as follows: cluster head selected in cluster head, that is, neighbours' cluster head in its communication range one it is closer apart from aggregation node
Neighbours' cluster head is sent to next-hop node as next-hop node, by collected data.
In one embodiment, the data of collection are sent directly to the cluster head of aggregation node according to first week of setting
Phase, periodically judge whether the current remaining of itself meets energy condition, if satisfied, cluster head is still directly by the number of collection
According to aggregation node is sent to, if not satisfied, cluster head selects indirect mode that the data of collection are sent to aggregation node, the energy
Amount condition are as follows:
In formula, PiFor the current remaining of cluster head i, Pi0For the primary power of cluster head i, PminFor preset energy lower limit,
G (i, O) is distance of the cluster head i to aggregation node, LimaxFor the maximum communication distance of cluster head i, v is preset declining based on energy
Subtracting coefficient, the value range of v are [0.85,0.95].
In the present embodiment, according to the ratio for the distance and the maximum transmission range of itself for itself arriving aggregation node when cluster head is initial
Relatively result selects suitable mode that the data of collection are sent to aggregation node；Further, the data of collection are directly transmitted
To aggregation node cluster head according to the period 1 of setting, periodically judge whether the current remaining of itself meets energy
Condition, according to whether the result for meeting energy condition determines the routing mode for sending data to aggregation node.The present embodiment is advantageous
Excessive data are undertaken in the cluster head for avoiding energy low and send pressure, are saved the energy consumption that the low cluster head of energy sends data, are extended
The working time of cluster head further ensures that data are transmitted to the reliability of aggregation node.
In one embodiment, a distance convergence section is selected in cluster head, that is, neighbours' cluster head of the cluster head in its communication range
The closer neighbours' cluster head of point is as next-hop node, comprising:
(1) cluster head by relative to it apart from the closer neighbours' cluster head of aggregation node alternately node；Construct alternate node
Collection, and initial priority is distributed for each alternate node:
In formula, Cij0For the initial priority of the alternate node j of cluster head i, G (i, j) be cluster head i to alternate node j away from
From, G (j, O) be the distance that the alternate node j arrives aggregation node, G (i, d) for cluster head i to its d-th of alternate node away from
From G (d, O) is distance of d-th of the alternate node to aggregation node, niThe alternative section concentrated for the alternate node of cluster head i
Point quantity；QiFor neighbours' cluster head quantity of cluster head i, QjFor neighbours' cluster head number of the alternate node j, Qi∩QjFor cluster head i with it is standby
The quantity for the common neighbours' cluster head for selecting node j to be possessed, w1、w,For preset weight coefficient, meet w1+w,=1；
(2) cluster head periodically obtains the information that its alternate node concentrates each alternate node according to the second round of setting,
The selection maximum alternative section of current priority is concentrated according to the priority of each alternate node of the information update, and then in alternate node
Point is used as next-hop node, wherein the more new formula of priority are as follows:
In formula, Cij(k) priority updated for the alternate node j of cluster head i in kth time, CijIt (k-1) is the alternative of cluster head i
The priority that node j is updated at kth -1 time, h are preset attenuation coefficient, and the value range of h is [0.1,0.2], yjIt is described
The current cache space of alternate node j, YjFor the initial spatial cache of the alternate node j, PjFor working as the alternate node j
Preceding dump energy, Pj0For the primary power of the alternate node j, r1、r,For the weight factor of resource ratio, meet r1+r,=1.
The present embodiment innovatively sets the index of priority, and cluster head is by the neighbour closer apart from aggregation node relative to it
Cluster head alternately node is occupied, constructs alternate node collection, and distribute initial priority for each alternate node, and according to alternative section
The resource consumption situation of point carries out regularly priority update, and when needing to select next-hop node, cluster head is in alternate node collection
It is middle to select the maximum alternate node of current priority as next-hop node.
The present embodiment correspondingly devises the calculation formula of initial priority and the more new formula of priority, according to the public affairs
Formula it is found that the alternate node that position is less compared with advantage, shared neighbor node and resource consumption is less have it is bigger excellent
First grade.Mode selects the next-hop node of cluster head through this embodiment, realizes the update of next-hop node, is conducive to ensure
The reliable forwarding of data balances the energy consumption and load of each cluster head, is further conducive to extend the service life of wireless sensor network.
In one embodiment, after cluster head updates the priority of alternate node every time, judge whether each alternate node meets
Following relay condition is rejected if not satisfied, sensor node concentrates the alternate node from alternate node:
In formula, Cij(k) priority updated for the alternate node j of cluster head i in kth time, CijIt (k-1) is the alternative of cluster head i
The priority that node j is updated at kth -1 time, Cij0For the initial priority of the alternate node j of cluster head i, e is preset decaying threshold
Value coefficient, the value range of e are [0.4,0.6].
The present embodiment sets relay condition, after cluster head cluster head updates the priority of alternate node every time, judges each alternative
Whether node meets following relay condition, rejects, has if not satisfied, sensor node concentrates the alternate node from alternate node
Conducive to so that the less alternate node of surplus resources, which loses, serves as the qualification of next-hop node, and then be conducive to improve selection next
The efficiency of hop node saves the energy consumption of selection next-hop node, the efficiency of improve data transfer.
