Network architecture for data communication

摘要

This invention relates to a network architecture for data communication between data sources and data destinations via network nodes and at least one data concentrator. According to the invention the nodes (2, 4) are conceived to communicate with a data concentrator (1) in both directions either via a permanently operative network (8) in the multihop mode or via an occasionally operative network (5) in wireless connection with mobile user nodes (6) in the nomadic mode. Means for commutation are provided to detect faulty multihop nodes and to activate nomadic nodes instead until the fault disappears, in order to maintain the overall functionality of the network. Moreover the network according to the invention allows to share the data collected by mobile users with other mobile users, thus forming a peer-to-peer network.

主权项

1. A method, comprising:
communicating, from a mobile user node, a poll message to one or more nodes within a communication range, the poll message being configured such that:
a first node of one or more nodes within the communication range configured to operate in a first mode is caused to respond to the poll message by communicating data collected by the first node to the mobile user node; anda second node of one or more nodes within the communication range configured to operate in a second mode is caused to ignore the poll message; receiving a data dump request from a data concentrator within the communication range; and communicating, in response to the data dump request, an amount of data collected by the mobile user node to the data concentrator.
