Abstract: In view of the fact that the independent network mobility model between nodes can’t reflect the mobile ad hoc network features under the real application scenario,nomadic group mobility model which is applicable in the military field and vehicle network is utilized.After constructing the corresponding system model,a multi-copy relaying algorithm between groups was put forward and the upper and lower bounds of network capacity and delay based on nomadic group mobility model under relaying mode can be deduced from which the corresponding rate of compromise is obtained.The simulation of the node mobility shows that the model possesses good mobility characteristics.The function curves of the relevant parameters prove that the better performance of the network can be obtained under this kind of mobility model.
