Composite multiple access high-dynamic networking method and device

The invention provides a composite multiple access high-dynamic networking method and device, and relates to the technical field of mobile ad hoc network communication. According to the method, when a conventional service message is transmitted in a network, a TDMA protocol is adopted for networking to carry out service message communication; when a sudden emergency service message needs to be transmitted in networking, local networking of part of cooperative task nodes of the network is initiated, and an SPMA protocol is adopted in the local networking to ensure the low-delay transmission requirement of the sudden emergency service. And after the sudden emergency service flow is finished, the node uses the TDMA again to carry out conventional service communication. The limitation of single MAC protocol networking communication in coping with different service requirements is solved. According to the method, low-delay transmission of emergent service flows is supported, high-dynamic communication in networkin
