MANET-based Nested NEMO Route Optimization

SLIDE 2

NEMO-to-NEMO

Mobile Network B Mobile Network A

Internet Core (Fixed)

Mobile Network C Mobile Network D Mobile Network E

Node in mobile network B wishes to communicate with node in mobile network A.

Home A Home B Home C Home D Home E

Basic solution: nested NEMO Con: suboptimal routes, nested encapsulation of all data traffic.

SLIDE 3

NEMO-to-NEMO

Mobile Network B Mobile Network A

Internet Core (Fixed)

Mobile Network C Mobile Network D Mobile Network E

Node in mobile network B wishes to communicate with node in mobile network A.

Home A Home B Home C Home D Home E

Smart solution: consider mobile routers as part of a MANET – run OLSR for route maintenance &

ptimization.

SLIDE 4

Internet-to-NEMO

Mobile Network B Mobile Network A

Internet Core (Fixed)

Mobile Network C Mobile Network D Mobile Network E

Node in network E wishes to communicate with node in mobile network A.

Home A Home B Home C Home D Home E

Basic solution: nested NEMO Con: suboptimal routes, nested encapsulation of all data traffic.

SLIDE 5

Internet-to-NEMO

Mobile Network B Mobile Network A

Internet Core (Fixed)

Mobile Network C Mobile Network D Mobile Network E

Node in network E wishes to communicate with node in mobile network A.

Home A Home B Home C Home D Home E

Smarter solution: OLSR within nested NEMO, inform home agent of A that point-of-attachment is throuth mobile network E. (Same overhead as 1 niveau of nesting) Possible combination with CR for shorter tunnels?

Goals

draft-clausen-nemo-ro-problem-statement-00.txt
contribute “MANET” solution to RO problem statement,
merge with other RO-problem-statements.
General:
route optimization in dynamic networks: long-time

MANET experience → avoid “reinventing the wheel,

possible cross-fertilization:

– requirements from NEMO → MANET, – experience/lessons learned from MANET → NEMO.
