Abstract
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.
Claims7
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, attaching a token specific to the sending node;
- (b) sending the messages with the tokens attached to other nodes of the network;
- and
- (c) rejecting for retransmission at each node any received message containing the token specific to that node.
A method of preventing network congestion upon restart of 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 stratifying reestablishment of communication among said nodes whereby restart is effected layer by layer, and within each link layer level, restart time is randomized.
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 including in each information packet to be sent to other nodes of said network a token specific to the sending node and by rejecting for retransmission at each node any received message containing the token specific to that node.
A method of keeping operational a wireless link layered network without operator intervention, comprising promulgating into the network, in response to changes at any node of the network, information as to such changes via message acknowledging SCMM, and assuring that only the node eliciting such an SCMM uniquely acts upon said information, providing the SCMM originated from a node having a link layer equal or lower than the eliciting node.
A method of reducing congestion in a wireless link layered network dynamically and without the intervention of an operator, comprising having all nodes that capture an SCMM from a node having a high utilization rate exceeding a preset level, remove said SCMM originating node from their respective routing lists, provided that the link layer level of the node originating the SCMM is equal or lower than each respective node capturing said SCMM.
