    摘要: A wireless mesh network is formed by nodes having a regular active schedule for transmitting and receiving messages, and a fast active schedule mode that is locally activated when a demand exists for transmission of a larger number of messages. As each node transmits a message to another node, the transmitting node includes a message buffer queue parameter that indicates the number of messages in the transmitting nodes, pending message queue. The receiving node determines, based upon the message buffer queue parameter received and its own capacity, whether to continue on the regular schedule, or to activate the fast active schedule. If the fast active schedule is activated, the receiving node sends a special acknowledge message back to the sending node, so that both nodes will transmit and receive messages over a fast active schedule link until the message buffer of the sending node has been reduced and the fast active schedule can be deactivated in favor of the regular active schedule.

    摘要: A method and apparatus are provided for allowing a field device to select a data communication provider among a plurality of available data communication providers. Preferably, the method includes periodically, or selectively, assessing the strengths and efficacy of data communication on one or more alternate data communication providers. The data communication provider with the strongest signal and/or most effective data communication is selected for use by the field device. Preferably, the field device logs events where it switches among data communication providers.
