Link layered networks with improved operation
A method and system for optimizing and keeping operational a wireless link layered network in which a system control and modifying message (SCMM) is elicited from nodes receiving information packets and based upon whether the node originating the SCMM is from a link layer level which is equal to or less than the link layer level eliciting the SCMM, rerouting or adjusting future transmissions can be effected or items like a less current time at a receiving node and a most recent utilization rate of a receiving node can be adjusted, recorded or set.
1. A method of preventing network oscillation in a wireless link layered network comprising a plurality of transceivers at respective nodes which route communications from any node to a then central node of the network and wherein said communications are in a form of information packets transmitted from one node to another, said method comprising the steps of:
(a) from each node from which a message is to be sent to other nodes of said network, setting a flag associated with the sending node in a message information packet;
(b) sending the message information packets with the flags set to other nodes of the network; and
(c) rejecting for retransmission at each node any received message containing the flag set by that node.
2. A wireless link layered network comprising a plurality of transceivers at respective nodes which route communications from any node to a then central node of the network and wherein said communications are in a form of information packets transmitted from one node to another, in which the continuous retransmission of the same message in a sub set of the nodes is prevented, said prevention being effected by setting in each information packet to be sent to other nodes of said network a flag associated with the sending node and by rejecting for retransmission at each node any received message containing the flag set by that node.
3. The wireless link layered network defined in claim 2 for a submetering system for at least one building formed with a main mode which can communicate with the central node configured to communicate with a plurality of main nodes, and a plurality of secondary nodes in said building each servicing a respective meter.
