I also had experienced such a thing in using TOSSIM. Its not intuitive to me in setting a topology what I want by specifying a radio model and a distance scaling factor. It seems to not correctly work. Current topology visualization of TOSSIM is also not enough in showing the neighborhood of a node under a fixed radio model. Is there any effort to fix or enhance those points of TOSSIM?

 

Thanks

Subject: [Tinyos-help] TinyViz, neighbor size--, network size++

 

Hi,

Not sure how to fix the following problem :

In TinyViz i came across the problem of unable to limit  the number of connected neighbors to say 4 or 5 while increasing the network size using the radio model option Fixed radius(10). When the network size is increased, as expectced the network becomes a higly dense network with neighbors ranging from 10 -15. So i tried changing the distance scaling factor by increasng the distance scaling factor and updating it hoping the a nodes radio range would get smaller. Thats the way i understood from the tutorial lesson  5 which states "Increasing the scaling factor will decrease the connectivity range of the chosen model." but increasing the scaling factor dont seem to decrease the radio range??( after update ) I guess i am missing something here?

 

Would you pls advice as to how to get nework size around 400 with  neighbor size aroung 5 for each node? using fixed radious(10) radio model??

 

Thanks

Siva
