 History  Routing in s  HWMP  Reactive/Proactive Routing  Hybrid Routing  RA-OLSR  Summery

 Drafts › Draft D0.01: March, 2006 (First Draft) › Draft D1.0: Dec, 2006 › Draft D1.06: July, 2007

 Necessary HWMP routing › Reactive Routing › Proactive Routing  Optional RA-OLSR

 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 i.

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

 Definition  Based on AODV and DSR  MAC-LAYER and RA-Metric  RREQ, RREP, RERR messages.

 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.

 Precondition for Hybrid Routing  How does it work?

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

 Multi-Point Relays Selection Criteria  Hello Messages  Advantages  Disadvantages

 s is a standard for WMN  Uses a Hybrid Routing  Reactive/Proactive/RA-OLSR  It’s NOT complete yet.
