    摘要: A communication network (600) includes a first communication device (102-1) and at least one other communication device (102-3), wherein the first communication device (102-1) and the at least one other communication device (102-3) are proximately located. The communication network further includes a transaction detector (625) coupled between the first communication device (102-1) and the at least one other communication device (102-3) for detecting one or more transactions intended for each of the proximately located communication devices. The communication network (600) further includes a bandwidth allocator (610) adapted to impede communication activity for a predetermined time for the at least one other proximately located communication devices (102-3), and activate communication activity for the predetermined time for the first communication device (102-1) in response to the transaction detector (625) detecting a transaction intended for the first communication device (102-1).

    摘要: A multi-hop wireless network includes an originator node, a proxy node, and at least one other node. The originator node generates a data packet and transmits the data packet to the proxy node. The proxy node receives and forwards to the at least one other node the data packet including an originator node address and a proxy node sequence number for an end-to-end groupcast sequence number.

    摘要: A multicast architecture and method of operation for multi-hop wireless mesh networks is provided. The multicast architecture is above the network infrastructure to identify a group of clients. These clients share the same application and communicate to each other by using a common multicast address.

    摘要: A method for tree based spatial TDMA scheduling in a multi-hop wireless network (100). A time slot is requested (101) for non-use by a requesting node to all neighboring nodes. Similarly, the requested time slot is next requested (103) for non-use from the requesting node to its parent nodes. If available, a time slot assignment is then requested (109) from the requesting node to its parent node where the time slot assignment is requested (111) from the parent node to the grandparent node of the requesting node. Finally, all neighboring nodes are then informed (117, 119, 121) if both the grandparent node and parent node grant the time slot request to the requesting node. The invention works to reduce packet collisions by providing link-slot formulation in combination with link direction to compensate for spatial reuse loss in a local optimization setting.
