In one embodiment, sensor node sends acquired environment number to base station by the form of multi-hop transmission According to specifically including:
(1) when netinit, base station builds message to all the sensors node broadcasts neighboring node list, receives the neighbour After occupying node listing structure message, sensor node obtains information of neighbor nodes by information exchange, and builds neighbor node row Table;When initial, sensor node randomly selects a neighbor node in its multiple neighbor node according to neighboring node list and makees For relay node, the environmental data of acquisition is sent to relay node, to forward environmental data by multiple relay nodes Mode sends acquired environmental data to base station;
(2) after a period T, sensor node obtains its neighbor node by the information exchange with neighbor node It is helped to forward the feedback letter of the total number of the number of environmental data packet and neighbor node forwarding environmental data packet in period T Breath, during next period T, sensor node calculates it to each neighbour according to feedback information every a time interval Δ t Occupy the degree of belief of node;
(3) sensor node divides reliability rating according to current degree of belief to each neighbor node, and neighbor node is divided For normal node, malicious node and selfish node three classes, and one is selected as relay node, by environment number from normal node It is sent to the relay node according to packet.
Wherein, set the calculation formula of degree of belief as:
In formula, Pij(T+ Δs t) indicate sensor node i in T+ time Δts to the degree of belief of its j-th of neighbor node,qij(T) number of sensor node i forwarding environmental data packets is helped in period T for j-th of neighbor node Mesh, Qj(T) total number of environmental data packet, D are forwarded in period T for j-th of neighbor nodeijFor sensor node i The distance between its j-th of neighbor node, DjoFor j-th of neighbor node to the distance of base station, DilFor sensor node The distance between i and its first of neighbor node, DloFor first of neighbor node to the distance of base station, niFor sensor node The neighbor node number of i, e-wΔtFor degree of belief decay factor, and w ∈ (0,0.1], a, b are all weight coefficient, and meet 0<a,b< 1。
Wherein, it is to the concrete mode of neighbor node division:Critical value h is trusted in setting first1, second trust critical value h2, For the arbitrary neighbor node j of sensor node i, work as Pij(T+Δt)∈(0,h1) when, neighbor node j is divided into malice and is saved Point, works as Pij(T+Δt)∈[h1,h2) when, neighbor node j is divided into selfish node, works as Pij(T+Δt)∈[h2, 1) when, it will Neighbor node j is divided into normal node.
The present embodiment sets the routing forwarding mechanism that sensor node sends acquired environmental data to base station, the road It divides the strategy of reliability rating according to degree of belief to each neighbor node by mechanism, innovatively proposing, and innovatively sets Determined the calculation formula of degree of belief, the calculation formula according to node for data forwarding packet the case where, the distance between node situation come Degree of belief of the neighbor node relative to sensor node is judged, and considers and trusts the case where decaying since the time elapses, tool There is certain robustness;With sensor node selection degree of belief high sensor node (the i.e. normal section that base station is multi-hop distance Point) forward environmental data packet, the reliability of environmental data transmission is improved, ensures that communication is stablized.
Wherein, every next period T, sensor node reacquire feedback information, and according to feedback information every One time interval Δ t calculates its degree of belief to each neighbor node, to which sensor node divides trust etc. to neighbor node The process of grade is dynamic, ensures that the degree of belief of calculating can more accurately weigh the state and transfer capability of neighbor node.
First trusts critical value h1It is the critical value of non-malicious node and malicious node, if it is, influence is sentenced The sensitivity of disconnected malicious node, if setting is excessively high, it will some non-malicious nodes are excluded except data transfer path, into And reduce the efficiency of routing.In one embodiment, critical value h is trusted in setting first according to the following formula1, second trust it is critical Value h2
In formula, niFor the neighbor node number of sensor node i, P0For the initial trust degree of neighbor node, P0=0.5.
The present embodiment proposes the first trust critical value h1, second trust critical value h2Setting formula so that trust it is critical Value setting can according to the variation of degree of belief dynamic change, so as to preferably according to degree of belief carry out sensor node Classification, improve and judge the sensitivity of malicious node, improve the efficiency of routing.
In one embodiment, for there are the relay nodes of multiple environmental data packets to be forwarded, according to environment number The forwarding of environmental data packet is carried out according to the descending sequence of the priority of packet, wherein the calculating of the priority of environmental data packet Formula is:
In formula,Indicate the priority of the μ environmental data packets to be forwarded of relay node j,It is described The environmental data quantity of the μ environmental data packets to be forwarded,For v-th of environmental data to be forwarded of relay node j The environmental data quantity of packet, i-Yj(μ) indicates to send the sensor of the μ environmental data packets to be forwarded to relay node j Node,It is relay node j to sensor node i-YjThe degree of belief of (μ), i-Yj(v) it indicates to send to relay node j The sensor node of this v-th environmental data packet to be forwarded,It is relay node j to sensor node i-Yj(v) Degree of belief, QjFor the relay node j environmental data packet quantity to be forwarded, z1、z2For setting weight coefficient and meet z1+z2=1.
The present embodiment innovatively sets the calculation formula of environmental data packet forwarding priority, and relay node is according to calculating The sequence of the priority gone out forwards environmental data packet, advantageously allows degree of belief height and account for cache big environmental data packet preferentially quilt Forwarding, improves the efficiency of cache management, reduces the congestion ratio of relay node, improves the speed of environmental data transmission, to The operational efficiency of wind-power engine room Intelligent fire-fighting automatic measuring and controlling system is improved on the whole.
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.
