Using NotificationBoard, modules can now notify each other about "events" such as routing table changes, interface status changes (up/down), interface configuration changes, wireless handovers, changes in the state of the wireless channel, mobile node position changes, etc.
The NotificationBoard has exactly one instance within a host or router model, and acts as a intermediary between module where state changes can occur and modules which are interested in learning about those changes.
NotificationBoard is accessed via direct C++ method calls (not message exchange). Modules can "subscribe" to categories of changes (e.g. "routing table changed" or "radio channel became empty"). When such a change occurs, the corresponding module (e.g. the RoutingTable or the physical layer module) will let NotificationBoard know, and it will disseminate this information to all interested modules.
The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.
If a module type shows up more than once, that means it has been defined in more than one NED file.
MFMobileHost | Models a mobile host with a wireless (802.11b) card in ad-hoc mode. This model contains the Mobility Framework's 802.11 implementation, Nic80211, and IP, TCP and UDP protocols. The mobility model can be dynamically specified with the mobilityType parameter. |
MobileHost | Models a mobile host with a wireless (802.11b) card in ad-hoc mode. This model contains the new IEEE 802.11 implementation, Ieee80211Nic, and IP, TCP and UDP protocols. The mobility model can be dynamically specified with the mobilityType parameter. |
BurstHost | Definition of an IP node with a transport generator that connects to IP directly, without TCP or UDP. |
OSPFRouter | IP router. |
QuaggaRouter | Quagga-based IP router. |
Router | IP router. |
StandardHost | |
TCPSpoofingHost | IP host with TCPSpoof in the application layer. |
Router6 | IPv6 router. |
StandardHost6 | |
LDP_LSR | An LDP-capable router. |
RSVP_LSR | An RSVP-TE capable router. |
WirelessAP | Models a 802.11 Access Point. It can be used in conjunction with WirelessHost, or any other host model containing WirelessNicSTA. |
WirelessAPSimplified | Models a 802.11 Access Point, but using a simplified NIC that does not support handovers. It should be used in conjunction with WirelessHostSimplified, or any other host model containing WirelessNicSTASimplified. |
WirelessAPWithEth | Models a 802.11 Access Point with Ethernet ports. It can be used in conjunction with WirelessHost, or any other host model containing WirelessNicSTA. |
WirelessAPWithEthSimplified | Models a 802.11 Access Point with Ethernet ports, but using a simplified NIC that does not support handovers. It can be used in conjunction with WirelessHostSimplified, or any other host model containing WirelessNicSTASimplified. |
WirelessHost | Models a host with one wireless (802.11b) card in infrastructure mode. This module is basically a StandardHost with an Ieee80211NicSTA added. It should be used in conjunction with WirelessAP, or any other AP model which contains Ieee80211NicAP. |
WirelessHostSimplified | Models a host with one wireless (802.11b) card in infrastructure mode, but using a simplified NIC that does not support handovers. This module is basically a StandardHost with an Ieee80211NicSTASimplified added. It should be used in conjunction with WirelessAPSimplified, or any other AP model which contains Ieee80211NicAPSimplified. |
