Abstract

Embodiments of system and method for coordination among neighboring networks for communications over shared physical medium are provided. In one aspect, a method comprises determining, by a first domain master of a first network domain, a first number of network nodes of the first network domain that interfere with data transmission on the physical medium by at least one network node of at least one other network domain, or a second number of network nodes of the at least one other network domain that interfere with data transmission on the physical medium by at least one network node of the first network domain. The method further comprises causing, by the first domain master, one or more network nodes of the first network domain to transmit data during one of a plurality of non-overlapping time slots of a MAC cycle.

Dependent claims

A method of coordination of physical medium access among neighboring domains of network nodes, the method comprising:

determining, by a first domain master of a first network domain, a first number of network nodes of the first network domain that interfere with data transmission on the physical medium by at least one network node of at least one other network domain, or a second number of network nodes of the at least one other network domain that interfere with data transmission on the physical medium by at least one network node of the first network domain;
and
scheduling, by the first domain master, each of one or more network nodes of the first network domain that interfere with or experience interference in data transmission on the physical medium by at least one network node of the at least one other network domain to transmit data during one or more of a plurality of non-overlapping time slots of a Media Access Control (MAC) cycle while allowing one or more other network nodes of the first network domain that do not interfere with or experience interference in data transmission on the physical medium by at least one network node of the at least one other network domain to transmit data anytime during the MAC cycle, each of the plurality of non-overlapping time slots allocated to a respective one of the first and the at least one other network domains.

A method of coordination of physical medium access among neighboring domains of network nodes, the method comprising:

determining, by a first domain master of a first network domain, a first number of network nodes of the first network domain that interfere with data transmission on the physical medium by at least one network node of at least one other network domain, or a second number of network nodes of the at least one other network domain that interfere with data transmission on the physical medium by at least one network node of the first network domain;
scheduling, by the first domain master, one or more network nodes of the first network domain to transmit data during one or more of a plurality of non-overlapping time slots of a Media Access Control (MAC) cycle, each of the plurality of non-overlapping time slots allocated to a respective one of the first and the at least one other network domains;
and
leasing, by the first domain master, from a second domain master of one of the at least one other network domain a time slot allocated to the one of the at least one other network domain to allow one or more nodes of the first network domain to transmit data on the physical medium during the leased time slot.

1 more element

A device that, when implemented in a first domain master apparatus of a first network domain including a plurality of network nodes, causes the first domain master apparatus to perform acts comprising:

determining a first number of network nodes of the first network domain that interfere with data transmission on a physical medium by at least one network node of at least one other network domain, or a second number of network nodes of the at least one other network domain that interfere with data transmission on the physical medium by at least one network node of the first network domain;
and
scheduling each of one or more network nodes of the first network domain that interfere with or experience interference in data transmission on the physical medium by at least one network node of the at least one other network domain to transmit data during one or more of a plurality of non-overlapping time slots of a Media Access Control (MAC) cycle while allowing one or more other network nodes of the first network domain that do not interfere with or experience interference in data transmission on the physical medium by at least one network node of the at least one other network domain to transmit data anytime during the MAC cycle, each of the plurality of non-overlapping time slots allocated to a respective one of the first and the at least one other network domains.
