  • A new data delivery scheme-PRD (Probability Replication Delivery scheme) is proposed for pervasive data gathering in DTMSN (Delay Tolerant Mobile Sensor Networks) that networks with intermittent connectivity in space. PRD consists of two key components for data transmission and queue management, respectively. The former makes decisions on when and where to transmit data messages according to the node delivery probability. The latter employs the message survival time based on probability and delivery copies to decide dropping for minimizing transmission overhead. Simulation results show that the proposed PRD data delivery scheme achieves the higher message delivery ratio with the lower transmission overhead and data delivery delay than other DTMSN data delivering approaches.
