Methods, devices and systems that use a control channel to coordinate quality of data communications in software-defined heterogenous multi-hop ad hoc networks are described. In some embodiments, an example apparatus for wireless communication in a network includes performing, using a control plane, network management functions over a control channel that has a first bandwidth, implements a frequency-hopping operation, and operates at in a first frequency band, and performing, using a data plane that is physically and logically decoupled from the control plane, data forwarding functions, based on a routing decision, over at least one data channel that has a second bandwidth and operates in a second frequency band different from the first frequency band.

摘要:
[OBJECT] To provide a network system which makes it possible to reduce the occurrence of a delay in data packet transfer processing even if periodic processing occurs.[ORGANIZATION] In a network system having a plurality of communication devices 10-1 to 10-5, the communication devices each include: an executing means (control part 12) that executes periodic processing whose processing occurs periodically; and an adjusting means (control part 12) that adjusts an execution timing at which the periodic processing is executed by the executing means, according to states of the other communication devices.
摘要:
A communication method of the SMF type for a network of nodes including a multicast group. The method includes the steps, performed by a first node, of: determining a set of respective multipoint relays; determining the nodes for which the first node is a multipoint relay; determining a routing table including identifiers of destination nodes and corresponding identifiers of next-hop nodes; receiving a multicast packet sent from a sending node, where the first node is a multipoint relay; checking if, for each node identifier of the multicast group, the entry in the routing table that includes a destination node identifier corresponding to the node identifier of the multicast group contains a next-hop node identifier that corresponds to the sending node, and if the counter contained in the multicast packet respects a relation with a limit; and determining whether to retransmit the multicast packet, on the basis of the outcome of the checking step.
摘要:
A method in a relay device for forwarding messages in a mesh based network comprises receiving a message to be forwarded (step 201), and determining whether the message is to be forwarded using a routing profile associated with the message (step 203). If so, the message is routed according to a routing profile (step 205). If not, the message is outed using a flood procedure (step 207).
摘要:
A device-implemented network with domains each having nodes, the nodes of each of the domains sharing network information with one another according to an intra-domain communication policy. An inter-domain protocol is configured to control communication between at least one of the nodes of one of the domains and at least one of the nodes of a different one of the domains. A broker is configured to be communicatively coupled to the nodes and configured to control communication according to the inter-domain protocol and to which all of the nodes of each of the plurality of domains are configured to send the network information.
摘要:
Systems and methods provide adaptability in a mobile ad hoc network (MANET), based on an existing protocol, such as adaptive hybrid domain routing (AHDR). The systems and methods are especially suited for fast changing topologies that may change after a reactive route discovery has been completed.
摘要:
When a roaming wireless communication device seeks to originate a communication, the device may originate the communication in a roaming system because the device has not yet run a next scheduled scan for a more preferred, home, system. In the disclosed method, the device may evaluate a current distance from where the device was located when it successfully communicated to a home system and may further evaluate a current duration from that successful communication. If the distance is threshold short and perhaps further if the duration is threshold short, then the device may originate the communication in the home system without having detected the home system through a scheduled rescan. Further, to help expedite origination, the device may set its origination power at the power that it used for the last successful communication.
摘要:
An access point operates in a frequency spectrum which is divided into master channels, each master channel further having a plurality of sub-channels, each sub-channel capable of supporting a wireless LAN session independently of any other said sub-channel. The access point assigns one of the sub-channels within the master channel to a requesting station according to a maximum number of user assigned to the particular sub-channel, or alternatively, the access point makes the assignment of a particular sub-channel to a particular station according the bandwidth requirement bandwidth requirement.
