Re: [Tinyos-help] question about tymo
Hi, > Do you know how long I wait to get the getRoute response. Simple answer: Look at the TYMO code how the do it! In ForwardingEngineM AMSend.send the a timer is started with 100ms. Then, they wait again 100ms, then 200, 400, 800 using a muliplicate approach. After 1,6s in total they give up. It's up to you if you want to follow their approach. The maximum wait time will also depend on your network.

Re: [Tinyos-help] question about tymo
Thanks for your replay.
Do you know how long I wait to get the getRoute response.
//my code is
//determine the physical hop: how far Ni is from GC
res=call RoutingTable.getRoute(GCAddress[gid], &rt_info);
//affichage parameter de la route
printf("EndDevice %02i: Printing route info res=%s\n",
TOS_NODE_ID, errType(res));
//if the route exist
if(res==SUCCESS)
{
print_route(&rt_info, sizeof(rt_info_t));
//save the physicalhop to the GC
physicalHop[gid]=rt_info.hopcnt;
}
Else
{
I wait ==> how long???
//again..
res=call RoutingTable.getRoute(GCAddress[gid],
&rt_info);
}

Hi Omar,
it's quite a while that I played around with TYMO - and actually it never
worked satisfyingly. So, I can only answer this question:

This is how TYMO works! It only knows its direct neighbors. If you ask for a
route to a different node, it returns an EBUSY but sends out a route request
packet to discover this route. So, you have to wait and ask for the route
again later. This is also TYMO is doing. See AMSend.send in
ForwardingEngineM.nc and RouteSelect.selectRoute in MHEngineM.nc
Best,
Daniel

In my protocol I need to determine number of hop between two nodes, so I used the interface RoutingTable, with the command "getRoute". Is it the best solution? Moreover, the command getRoute returns SUCCESS only if the nodes are one hop far from (directly connected), and it returns EBUSY if the nodes are more than one-hop far from. Can you tell me how to resolve this problem?
