According to the embodiment of the present invention, provide a kind of micropower wireless network ad hoc network method, Fig. 1 is the flow chart of the method, specifically comprises:
Step 101: host node initiates broadcast networking order at common signal channel group hop-by-hop, carries out data interaction in privately owned channel group and child node, notifies the order of various level child node forwarding of packets broadcast networking simultaneously.
Wherein, also comprise the step of initialization host node before step 101, and this step is after concentrator powers on.Initialization host node specifically comprises: carry out initialization to host node allocation address, network numbering and multiple channel.
Concrete, host node, by repeatedly sending various level broadcast networking command frame, travels through the child node of whole network, for the node networked, only forwards a networking commands.
Step 102: after host node receives the networking beacon of concentrator transmission, obtains node identification, host node pass-along message to the time cost of its 1 jumping scope child node, carries out scan channel, field intensity collection simultaneously.
Step 103: in the given time, host node waits for child node reported data, collects and stores the topological data of all child nodes, according to the configuration requirement of concentrator, in conjunction with field intensity information, calculate also memory time cost, dynamically carry out networking; Topological data comprises the mark of all child nodes, Centroid to time cost, the field intensity information of child node.
Time cost is the time overhead that host node arrives direct subordinate child node, and scan channel is scan the channel group of specifying, and select the channel that interference is less, field intensity is collected as from effective signal frame, extracts field intensity information and stores.
Wherein, in step 103 in conjunction with field intensity information, calculate and memory time cost, comprising: according to the size of host node pass-along message to the time cost of its 1 jumping scope child node, the topological data of child node at the same level is sorted, and stores data; The data stored are node identification, host node passes and sends a message to the time cost of child node, and node identification and host node pass the corresponding relation of the time cost sending a message to child node.

The channel that step B2, source node jump to record communicates with destination node;
Step B3, source node jump to a receive channel of destination node, then send packet to destination node, start timer, at present channel wait acknowledge bag simultaneously;
If step B4 receives confirm bag, then this communicates successfully, and source node switches back the receive channel of oneself, and records the corresponding relation of this source node good and destination node communication channel;
If step B5 does not receive confirm bag, then source node jumps to the channel not attempting communicating of destination node, re-starts communication of trying, if all channels have all repeatedly been attempted communicating, then this communication failure, source node switches back oneself receive channel.
Concrete, the path selection mechanism of this network-building method is, after the host node networked or child node receive beacon request, reply the beacon that includes route cost, the calculating of route cost will consider RSSI (ReceivedSignalStrengthIndication, the signal strength signal intensity instruction received) value, according to scope and the threshold value of the effective RSSI value of communication, calculate route cost, between node, the way of communication is more, route cost between them is larger, is the route cost sum between often jumping.Child node, after having calculated the route cost between each superior node, according to the principle of Minimal routing cost, chooses the superior node of node as this node.
A kind of micropower wireless network ad hoc network method that the embodiment of the present invention provides, by automatic switchover scan channel, field intensity is collected, obtain the time cost arriving each child node, carry out collection by many-sided data to calculate, consider and realize fast self-networking, improve the efficiency of networking to a great extent, the networking time can be saved, improve the stability of network service.
Introduce the process of this micropower wireless network ad hoc network method below in detail.
After concentrator work, send the beacon of network organizing, before this work, first should configure the physical address of host node, configure the physical address of data acquisition equipment to be networked, then start to create network.Host node is scanned by channel energy after receiving and creating networking command, selects n the channel that interference is little in multiple channels of candidate.Afterwards, host node carries out active scan, judges whether the network numbering preset exists conflict, if there is conflict, then and host node stochastic generation network numbering, then judge; If not conflict, then networking success.
Scene is existed to the situation of concentrator close together each other, the situation of co-channel interference may be there is, when needs create network, different channel group should be selected, data acquisition equipment and the mutual co-ordination of concentrator, together complete the building work of network.
Concentrator sends networking beacon, networking beacon is first sent to the child node within the scope of its 1 jumping, receive the child node of this beacon, also need to carry out continuation to information to forward, the child node making MESH network all can receive information, also can receive the field intensity information of adjacent node, field intensity information comprises ID, the relevant information such as address and signal strength signal intensity of child node, by the mode of multi-hop, relevant information is fed back to concentrator and host node afterwards simultaneously.
After concentrator sends networking beacon, in time slot, field intensity can be sent and collect instruction, carry out the collection of field intensity information, the instruction of this field intensity information forwards in the child node of each level by the mode of automatic frequency-hopping, after data acquisition equipment and child node receive instruction, can by field intensity information by wireless child node module forwards to concentrator, after concentrator receives information, set up corresponding field intensity information database.In networking process, need to analyze the field intensity information of this database, calculate good communication path.
After data acquisition equipment powers on, search for the child node or host node that have networked, simultaneously first determine the fixed address of child node, carry out scan channel, namely in multiple channels of multiple channel group of setting, send beacon request respectively, networking child node or host node, after receiving beacon request, reply beacon, what notify child node to be networked oneself enters net state, and child node to be networked collects the beacon received on each channel.When all channels are all scanned, then the end of scan, based on network access node, calculate child node to be networked arrives the path of host node networking path through the node respectively networked, the node selecting networking path minimum is as the father node of oneself, and request networks, and application adds network.Be selected as higher level from node receive network request after, the fixed address of child node to be networked is sent to host node.Host node receives after the information of the child node networked, and if the verification passes, then records the information of this point, distributes one and enters net address and return agreement inbound information; Otherwise, then do not record this information, return refusal inbound information.After the information that the child node networked receives host node, if agree to network, then successfully add network, start normally to work; If do not agree to network, then restart networking flow process, until add network.Wherein, the flow process of child node networking and the interaction flow of application networking are specifically see shown in Fig. 2 and Fig. 3.
When node carries out networking, when causing receiving network data, child node is in multiple receive channel, switch each Channel Received Signal successively, if be last channel, then switch to first channel, cyclic switching, when node is switched to a receive channel, start timer, if in a period of time, node can detect that signal exists, then timer is by a regular time of increase, if do not detect that signal exists, then switches to next receive channel.
When there being non-network access node, or having new data acquisition node to need to add, these nodes need initiatively to apply for networking, and initiate in each channel group the request of networking, simultaneously at privately owned channel receiving information, scanning receives response, if any response, then and the field intensity information of record response node, when response time slot is complete, all field intensity informations received are carried out calculating and sorting, selects an optimal path, report host node to set route.As do not received response message, then switch each channel successively and send the request of networking, until all channels are sent completely.
When host node does not receive child node response continuously, when communication disruption, need to repair path.Child node is searched in host node broadcast, after child node receives node broadcasts, information is judged, as for this node, then a response is made to host node, otherwise by the route cost in packet and field intensity information value value, calculate the route cost that oneself arrives host node, wait for a time period.Within the stand-by period, if child node receives new node checks broadcast, still calculate its route cost, compare with existing route cost, if larger than existing cost, then packet discard, if be less than existing route cost, then replace old packet with new packet.
