Embodiment Construction
[0023] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0024] Figure 4 As a schematic diagram of an adaptive data transmission strategy for situational awareness, the present invention specifically includes the following steps:
[0025] S1: Each node in the network obtains network information and the duration of the encounter between the current node and other nodes in the network t i,j , Total network operation time t total ,Combining transitivity and time decay at the same time, estimate the probability of encounter with the destination node;
[0026] S2: Each node in the network estimates the remaining energy of its own node based on the energy consumption of the following three aspects: forwarding energy consumption E t , Receive message energy consumption E r And routing discovery energy consumption E f ;
[0027] S3: The node is aware of the situation of the network topology: the mobile n...
