A Delay Tolerant Network Routing Policy Based on Optimized Control Information Generation Method

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.
