| Summary: | Current research examining delay tolerant network (DTN) routing policies mostly focuses on network environments with relatively abundant resources and lacks consideration of resource-constrained special network environments. To overcome this limitation, a resource-constrained DTN routing policy (RC-RP) based on an optimized control information generation method is proposed. In contrast to traditional DTN routing policies, RC-RP can utilize local node resources to select the relay node and perform copy control according to the optimized control information to achieve a better overall network performance. The simulation results show that the performance of the RC-RP routing policy is clearly superior to that of the epidemic routing policy, SAW routing policy, and RBL routing policy.
