Abstract
Distributing a message in a network may include transmitting, via a contention-free access channel, the message from an originating node to a first set of nodes neighboring the originating node, and designating a subset of the first set of nodes as relay nodes. A first one of the relay nodes may then relay, via the contention-free access channel, the message to a second set of nodes neighboring the first relay node.
Claims30
A method of distributing messages in a first network, the method comprising:
- transmitting, via a contention-free access channel, a message from an originating node to a first set of nodes neighboring the originating node;
- designating a subset of the first set of nodes as relay nodes;
- and
- relaying, via the contention-free access channel, the message by a first one of the relay nodes to a second set of nodes neighboring the first relay node.
A network for distributing messages, comprising:
- a first set of nodes, in which a subset thereof are designated as relay nodes;
- and
- an originating node for transmitting, via a contention-free access channel, a message to the first set of nodes, the first set of nodes neighboring the originating node,
- wherein a first one of the relay nodes is for relaying, via the contention-free access channel, the message to a second set of nodes neighboring the first relay node.
A method of registering a node in a network, the method comprising:
- transmitting a registration request, using a designated slot in a contention-free access channel, from a registering node to a master node within a network;
- receiving at the registering node a temporary node-identifier and an identification of a temporary slot in the contention-free access channel;
- and
- transmitting information from the registering node to the master node, using the temporary node-identifier and the temporary slot, to identify the registering node to the master node.
26-38. (canceled)
A system for registering a node in a network, comprising:
- a master node;
- and
- a registering node for i) transmitting, using a designated slot in a contention-free access channel, a registration request to the master node, ii) receiving a temporary node-identifier and an identification of a temporary slot in the contention-free access channel, and iii) transmitting information to the master node, using the temporary node-identifier and temporary slot, to identify the registering node to the master node.
40-52. (canceled)
A method for resynchronizing a node with a network, the method comprising:
- receiving at a resynchronizing node, via a contention-free access channel, a first message from a supplier node within the network;
- transmitting from the resynchronizing node to the supplier node, after receiving the first message, a resynchronization request comprising a reference to a point in time at which the resynchronizing node lost communication with the network;
- and
- receiving at the resynchronizing node from the supplier node, based on the reference, a first missed message.
