IEEE 802.11s (mesh) draft standard implementation.
Current model conforms IEEE 802.11s D3.0 draft version and includes Peer Management Protocol and HWMP (routing) Protocol implementations.
The multi-interface mesh points are supported as an extension of IEEE draft version 3.0. Note that corresponding helper creates single interface station by default.
Implementation of 802.11s draft standard consists of two main parts: Peer management protocol and HWMP - Hybrid Wireless Mesh Protocol.
The task of peer management protocol is the following: -open links detecting beacons and starting peer link finite state machine. -close peer links due to transmission failures or beacon loss.
If peer link between sender and receiver does not exist, the packet will be dropped. So, the plug-in to peer management protocol is the first in the list of ns3::MeshWifiInterfaceMacPlugin
Peer management protocol consists of three main parts:
Procedure of closing peer link is not described detailed in 802.11s draft standard, so in our model the link may be closed by:
Also Peer management protocol is responsible for beacon collision avoidance, because it keeps beacon timing elements from all neighbours. Note, that PeerManagementProtocol is not attached to MeshPointDevice as a routing protocol, but the structure is similar: the upper tier of protocol ns3::dot11s::PeerManagementProtocol and its plug-in is ns3::dot11s::PeerManagementProtocolMac.
HWMP is implemented in both modes – reactive and proactive. Also we have implemented an ability to transmit broadcast data and management frames as unicasts (see appropriate attributes). This feature turns off at a station when the number of neighbours of the station is more than a threshold.
