Flow against pipeline leakage and the pipe network sudden burst pipe to pipeline leakage flow for the application objects, dynamic key path is design widely used for pipeline leak monitoring. Security schemes ofpair wise key establishment ensure communication security in wireless sensor networks. Dynamic key-path in pair wise key establishment farther increases communication security in the networks. Dynamic key is first proposed pre-allocation program and preset algorithm, derived based on local weak connectivity of the cluster concept of dynamic key path analysis of the implementation process and its algorithm, sBIBD （symmetric balanced incomplete block design） algorithm has better forecasting network congestion phenomenon, adaptive real-time adjustments to the network transfer rate and reduce the loss of network data rate. The algorithm has a good reliability and efficiency to ensure that the flow in the pipeline leak monitoring network to gain better link utilization, TCP-friendly and to reduce the packet loss rate link is a wireless sensor network for safe and reliable.
