[Alfonso] Status of OLSR_ETX module

[Rehan]

Hi, 

I have done detailed experimentation on end-to-end throughput analysis with DSR+ETX. 

Now I would like to see how they compare with running OSLR+ETX for the same network topologies and traffic etc. 

In this regard, I have two questions. 

1) Is the OSLR_ETX module in INETMANET complete and stable?

From prior experience, for example DSR+ETX module would perform all the (ETX related) proactive broadcasts and meaure link quality. But for route selection it would pick first-come-first-serve RREQ. 

2) I am finding it difficult to specify parameters for OSLR that can be equivalent to my DSR setup parameters. 

For a given DSR setup as follows: 

**.routingProtocol="DSRUU"

**.PrintDebug = true

**.FlushLinkCache = true

**.PromiscOperation = false ###mod

**.UseNetworkLayerAck = true ###mod

**.BroadcastJitter = 20 # 20  ms

**.RouteCacheTimeout = 200   

**.SendBufferTimeout = 30# //30 s

**.SendBufferSize = -1

**.RequestTableSize = -1

**.RequestTableIds = -1

**.MaxRequestRexmt = -1 #// 16,

**.MaxRequestPeriod = 10 #//10 SECONDS

**.RequestPeriod = 500 #//500  MILLISECONDS

**.NonpropRequestTimeout = 30# //30  MILLISECONDS

**.RexmtBufferSize = -1 #//MAINT_BUF_MAX_LEN

**.MaintHoldoffTime = 250# //250 MILLISECONDS

**.MaxMaintRexmt = 2 # //2

**.TryPassiveAcks = true #//1

**.PassiveAckTimeout = 100# //100 MILLISECONDS

**.GratReplyHoldOff = 1 #, //1 SECONDS

**.MAX_SALVAGE_COUNT = 15 

**.LifoSize = 20

**.PathCache = true

**.ETX_Active=true   

**.ETXHelloInterval = 0.1 #${ETXHelloInterval=0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.9,1.2} #0.1 #2, // Second

**.ETXWindowNumHello = 100   # 30 Seconds per Average!

**.ETXRetryBeforeFail=-1

**.RREPDestinationOnly = true

**.RREQMaxVisit =5 # // Max Number that a RREQ can be processes by a node #Default was 10

Can we say my OSLR parameters are equivalent for a fair comparison? (Given that all other parameters from udp, wlan etc are same)

**.routingProtocol="OLSR_ETX"

**.Willingness = 3

**.Hello_ival = 0.1s

**.Tc_ival = 5s

**.Mid_ival = 5s

**.use_mac = 0 #1

**.Mpr_algorithm = 1

**.routing_algorithm = 1

**.Link_quality = 2

**.Fish_eye = false

**.Tc_redundancy = 3

**.Link_delay = true #//default false

**.C_alpha = 0.2

Thank you for your time, and kind assistance. 

Best regards, 

Rehan

You can set RREQ multivisit true in the DSR protocol, in this case, if a node has received a RREQ but the stored path in the packet is diferent that the stored path, the node can propagate the RREQ .

And there is a long time since I port the ETX mechanims, I can't garantee that the code is stable becuase I haven't tested it in a long time

Hello Alfonso,

Regarding Multi-visit be true in DSR,

**.RREQMaxVisit =5

or do you mean:
**.RREPDestinationOnly = true

should rather be:
**.RREPDestinationOnly = false

Thank you as always, for your time.

Best regards,
Rehan

RREQMaxVisit

 

RREPDestinationOnly = true, intermediate RREPs aren’t allow
