If graph G(V, E) represents femtocell topology where vertices V and edge set E show femtocell and their interfering relation respectively. We may say, there is an edge between two femtocells if their distance is less than 2R. Considering this scenario of the femtocell, can we model the femtocell as a unit disk graph?
As I'm from Mathematics background, googled the word femtocell & got some idea about this. It seems like you want maximum coverage with optimal deployment of femtocell . For that it's good idea to use unit disk graph technique to model femtocell.
Dear Ajay,
I suggest to you aliks and attached files in topics.

I would answer yes, if the femtocell is being used outdoors, and you are looking for seamless coverage between femtocells. But frequently, femtocells are used to improve indoor coverage, without offloading to WiFi. So in this case, the femtocell coverage is more or less confined to inside the building.
(Parenthetical editorial comment: While in principle, femtocells are the natural progression of the cellular model, to reuse spectrum even more effectively, some of the interest in femtocells is tied to LTE-U. This is where the cellular service gets to grab free, unlicensed spectrum, the same spectrum used by WiFi, to sell revenue-making cellular service. If you offload to WiFi, instead, the cell company does not make revenue from those sessions.)
@Albert Sir, @Mohamed-Mourad Lafifi
Thank, you sir for such nice answer, but I did not get, what additional factor will play in role as per unit disk graph aspect when deployment is done in multi stories buildings in the case of indoor or deployed outdoor to enhance the coverage area. If femtocell radius is fixed. As I got, it may just change the interfering relation with its neighboring cells and unit disk graph density will vary base on that.
