Based on MAC address. Uses radio-aware routing metric. Unicast, Multicast and Boradcast. Path Selection vs. routing. Single/Multiple radio devices.

Extension of 4-address frame. MAC layer is amended. Physical Layer stays intact. Compatible with other layers. Mesh security is based on 802.11i.

Foundation: Adaptation of RM-AODV Default routing protocol for IEEE
802.11s Reactive/proactive routing
components. Used in IEEE 802.11s because
› Mobile Nodes› Static Nodes

Def: Maintain routes to all destinations Why Proactive routing? Registration/Non-registration Modes

RANN messages Nodes have path to root Root has no information about children

Each node has registers itself to the root.
Nodes have Path to the root Root has list of all nodes inside
network.

Optional proactive routing protocol of the emerging IEEE 802.11s framework.
Adaptation of OLSR Routing Metric: Radio-Aware Use of Mac instead of IP Why RA-OLSR?
