PSO-based proactive routing in Delay Tolerant Network

Delay Tolerant Network (DTN) is a new wireless networking architecture. Although it is designed for the environment where network partitions frequently appear, how to realize the routing algorithm in DTN is still an open question until now. In this paper, we propose a novel proactive routing protocol based on Particle Swarm Optimization (PSO) algorithm to support the data exchange between isolated nodes. The simulation results show that: our scheme could effectively reduce the network latency and could provide better flexibility and extensibility.
