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. |
