[manet] DYMO and other routing protocols

[David Murray <30179198 at student.murdoch.edu.au>]

Hi,

I am wondering how DYMO fits in with the other routing protocols. I 
have read a number of papers that discuss how on-demand routing 
protocols like DSR/AODV work better in highly mobile environments where 
movement is fast, CPU and memory are low and batteries are limited. 
Equally, in situations where movement is very low, and there are no 
power limitations, protocols like OLSR/TBRPF/STAR perform better.

So, I have a mental picture of OLSR/TBRPF being predominantly used in 
stationary 802.11 mesh devices and AODV/DYMO being used to connect 
users mobile devices ush as phones and PDAs. Is this correct or are 
things not quite as simple as this? (I know RFC 2501 discusses MANET 
applications and characteristics but the discussion is quite general)

If this is correct, it seems to me that DYMO and AODV are used in very 
similar situations (the ad hoc interconnect between users devices). I 
am aware that DYMO is a simplified version of AODV both in code and 
network operation. It seems like the major difference is the path 
accumulation feature in DYMO which allows nodes to append their 
information to a RREP to give other nodes better knowledge of the 
topology. It also seems that the hello feature has been removed in 
DYMO. So, is DYMO likely to be a replacement for AODV or do they have 
different uses/applications?

Thanks for your time

Dave
