Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
Embodiment 1
Network environment as shown in Figure 1,8 ultrashort wave frequency hopping stations that use ultrashort wave wireless self-networking module are arranged, all radio station are with TDMA mode access network, the networking module is provided with IP address unique in the network for each radio station, start back networking module controls radio station sends routing iinformation and the temporal information that the networking module produces, up to mutual one time of the routing iinformation in all radio station and temporal information, the networking module is according to routing iinformation and the temporal information received, the time reference radio station of the radio station of IP address minimum in the network as network selected in the foundation of network route simultaneously, set up to this network and finish.
When the radio station has data to send, the radio station is given the MANET module data, this networking module is calculated sending time slots, because the whole network time reference is unified by mixed-media network modules mixed-media, when a radio station when own time slot sends data, other radio station is in accepting state at this time slot, guarantees to have in the network radio station of information transmission under the networking module controls, can be by other station interference.Radio station 1 has data to send, and the destination address of these data is radio station 6, and the networking module in radio station 1 is at first searched the path that arrives destination address in the protocol process module of oneself, if destination address one is jumped can reach, and then 1 sending time slots directly sends data in the radio station; If it is unreachable that destination address one is jumped, then 1 sending time slots sends data to next hop address in the radio station, it is a linking up station on the path, data are by the ultrashort wave wireless self-networking resume module in this radio station, this module controls linking up station is transmitted data, and radio station 4 is exactly the next hop address that radio station 1 arrives radio station 6 among the figure one.Carry the destination address of these data and the path that data will be passed through in the data that radio station 1 sends, after this information is received in radio station 4, data are submitted to ultrashort wave wireless self-networking module, this module finds that destination address is not oneself, just forward this information to and reach next hop address, promptly the radio station 7.Radio station 7 forwards this information to and reaches radio station 6, after the networking module that is in each radio station on the data transfer path is received data, ultrashort wave wireless self-networking module all will generate confirmation, and send, and represents that this data message receives, finally finishes the transmission of data message.In data transmission procedure, if the path failure of before having found out, then networking module change data transfer path, and other mixed-media network modules mixed-media that sends in the routing update information informing network is changed the path that arrives the purpose radio station.This is the process that radio station 1 sends data to radio station 6.If in the network is not that this data message is received in the radio station that is on the path, the ultrashort wave in this radio station is wireless, and the automatic network module does not process.The process of Point-to-Point Data Transmission that Here it is under ultrashort wave networking module controls.
Radio station 1 has data to broadcast, mixed-media network modules mixed-media becomes the broadcast data newspaper to data encapsulation, after broadcast message is received in radio station in this radio station one jumping scope, the networking module in these radio station will be transmitted to their interior radio station of a jumping to this information, by that analogy, this information is received in the radio station of all in network.Be radio station 1 broadcast message, after receive in radio station 2,3,4, can transmit this information at the time slot of oneself, receive in radio station 5,7,8 then, transmits this information at the time slot of oneself then, and receive in last radio station 6, broadcast this information at the time slot of oneself, this information is received in all radio station in this network.
Ultrashort wave wireless self-networking module data transmission procedure under the TDMA access module has only been described above.Under the CSMA pattern, identical under data transmission procedure and the TDMA pattern, radio station access way difference just.
