Abstract
A method and apparatus make use of a multiple receiver frame aggregation for creating data units so that they require acknowledgment of a single packet data unit by a group of several intended receivers. A multi-hop topology information regarding the neighborhood of a destination node can be used to derive the intended receivers which acknowledge a packet transmission besides the primary destination node of the packet.
Claims14
An apparatus for broadcasting packet data by a sender node to a destination node multi-hop wireless network, said apparatus comprising:
- a memory storing instructions;
- and
- a processor which, when the instructions are executed by the processor, configure the processor:
- to derive a multi-hop topology information of a target node;
- derive a reception history of neighboring nodes of a selected node;
- to determine a group of receiving nodes based on said multi-hop topology information and the reception history;
- and
- to specify at least two receiving nodes of said group in a multiple receiver frame aggregation for packing data units, wherein the at least two specified receiving nodes and the destination node must send back acknowledgements to the sender node.
A method of broadcasting packet data by a sender node to a destination node in a multi-hop wireless network, said method comprising the acts of:
- deriving by a processor a multi-hop topology information of a target node;
- deriving a reception history of neighboring nodes of a selected node;
- determining a group of receiving nodes based on said multi-hop topology information and the reception history;
- specifying at least two receiving nodes of said group in a multiple receiver frame aggregation for packing data units;
- and
- the at least two specified receiving nodes and the destination node sending back acknowledgements to the sender node.
A non-transitory computer readable medium comprising computer instructions which, when executed by a processor, configure the processor to perform the acts of:
- deriving a multi-hop topology information of a target node;
- deriving a reception history of neighboring nodes of a selected node;
- determining a group of receiving nodes based on said multi-hop topology information and the reception history;
- specifying at least two receiving nodes of said group in a multiple receiver frame aggregation for packing data units;
- and
- the at least two specified receiving nodes and the destination node sending back acknowledgements to the sender node.
