Receiving great interest from the research community, the concept of delay/disruption tolerant networks (DTNs) is without the contemporaneous end to end connectivity to bridge communication in the challenged networks, suffering from sparse network density and frequent disruption. In this paper, our motivation is to firstly adopt geographic information instead of history encounter information to relay message. Then we argue it is unreasonable to rely on realtime location of destination to relay message due to sparse network density and high mobi...
