Mesh Network System and Techniques

摘要

The present relates to a node to be integrated in a network of wirelessly connected nodes, to a network system, to method for operating a node of a network, and to a method for communicating within a network. A method is disclosed for communicating within a network of cooperatively synchronized nodes, configured to broadcast data packets to the network during broadcast phases through a flooding mechanism, each data packet comprising hop data. The method comprises, for each broadcast phase, broadcasting a data packet from a source node during a predetermined time slot; and receiving the data packet at one or more destination node during said predetermined time slot. The broadcasting and receiving are repeated according to the hop data, at respective predetermined time slots, wherein each destination node corresponds to a source node in a next execution of broadcasting and the data packet received corresponds substantially to the data packet to be broadcasted in the next repetition.

1. A node to be integrated in a network of wirelessly connected nodes, the node comprising:
a main module comprising a main controller having a main clock, the main controller being operable between an active configuration wherein the main clock oscillates and an inactive configuration wherein the main clock sleeps; a digital serial bus connected to the main module, the digital serial bus being operable under a communication protocol which is configurable to embed timing information; and an external sleep controller being connected to the main module via the digital serial bus to operate the main controller between the active and inactive configurations based on said timing information.
