Abstract
Different bitloading may be applied to different subsets of an Multicast (MC) group. Alternatively, the same bitloading may be applied to several or all of the subsets of an MC group. Such subset, or MC subgroup, may be formed as a result of considering bitloading capabilities of nodes of an MC group. In one embodiment, information is transmitted multiple times, once for each MC subgroup, each subgroup with a different bitloading. Such a process may improve overall throughput and efficiency for delivering packets to nodes of a network.
Claims12
A method, comprising:
- associating one or more nodes with a channel identifier (ID), said one or more nodes comprising a subgroup of a multicast group comprising a plurality of nodes;
- transmitting one or more probe signals along links among said one or more nodes to determine particular modulation techniques for said links;
- determining which nodes of said plurality of nodes should be associated together in said subgroup based, at least in part, upon said particular modulation techniques for said links;
- detecting an exiting node among said nodes in said subgroup;
- determining a likelihood that said exiting node returns to said subgroup;
- and
- modifying said particular modulation techniques in response to said likelihood.
A method, comprising:
- associating two or more nodes with a channel identifier (ID), said two or more nodes comprising a subgroup of a multicast group comprising a plurality of nodes;
- transmitting one or more probe signals along links among said two or more nodes to determine particular modulation techniques for said links;
- and
- determining which nodes of said plurality of nodes should be associated together in said subgroup based, at least in part, upon said particular modulation techniques for said links;
- detecting an exiting node among said nodes in said subgroup;
- determining a likelihood that said exiting node returns to said subgroup within a duration of time following removal of said exiting node from said subgroup;
- and
- modifying said particular modulation techniques in response to said likelihood.
A computer readable non-transitory medium having machine-readable instructions stored thereon which, if executed by a computing platform, are adapted to enable said computing platform to:
- associate one or more nodes with a channel identifier (ID), said one or more nodes comprising a subgroup of a multicast group comprising a plurality of nodes;
- initiate transmission of one or more probe signals along links among said one or more nodes to determine particular modulation techniques for said links;
- determine which nodes of said plurality of nodes should be associated together in said subgroup based, at least in part, upon said particular modulation techniques for said links;
- detect an exiting node among said nodes in said subgroup;
- determine a likelihood that said exiting node will return to said subgroup;
- and
- modify said particular modulation techniques in response to said likelihood.
An apparatus comprising:
- means for associating one or more nodes with a channel identifier (ID), said one or more nodes comprising a subgroup of a multicast group comprising a plurality of nodes;
- means for transmitting one or more probe signals along links among said one or more nodes to determine particular modulation techniques for said links;
- means for determining which nodes of said plurality of nodes should be associated together in said subgroup based, at least in part, upon said particular modulation techniques for said links;
- means for detecting an exiting node among said nodes in said subgroup;
- means for determining a likelihood that said exiting node will return to said subgroup;
- and
- means for modifying said particular modulation techniques in response to said likelihood.
