Probabilistic Route Mechanism of Considering Communication Time - PROPHETCCT

DTN (delay-tolerant network) is a network model which is abstracted from many examples of networks in recent years. In this network model, a long period of network division happens frequently, so in a given time a period of end-to-end path does not exist. As DTNpsilas this unique topology nature, the traditional network architecture and routing mechanism is no longer applicable. If the information canpsilat be predicted, the probabilistic route mechanism which is called PROPHET is used. In this paper, with introducing the communication time of nodes to the computation of communication prediction, algorithm PROPHETCCT is proposed. The simulation proved that PROPHETCCT algorithm effectively improve the DTN network routing performance.
