low success ratio when this fork of oversim used with inetmanet-2.0

[mohammad-almojamed]

Hi, i am working on oversim with inetmanet. whenever i run a simulation of any protocol with simple underlay or inet underlay it gives a bad performance. for example simulating Chord simple or inet underlay with no churn gives 32% success ratio. where running the same simulation with the same parametres on the normal oversim with inet gives 100% success ratio. i copied the ( defult.ini, and omnetpp.ini from the orginal oversim to oversim with inetmanet but no luck to get better performance.

your help is appreciated. M

Hi, i think the problem is with the BaseOverlay.cc. this class did not fetch the parameter " overlayId" which result in having different values for overlayId and creating new Chord ring each time a new node is added to the network during initialization ( Chord::changeState). and the node is then treated as a bootstrap node. so after adding the following line when i run chord simulation with no churn i get 100% success ratio. overlayId = par ("overlayId"); in function BaseOverlay::initialize(int stage) when the stage is MIN_STAGE_OVERLAY.

Am I right?

i will check, but have sense

I have uploaded your suggestion, it is true that the overlayId was not initialized, in this condition the initial value is a random value
