Thanks Omprakash I was configuring the multihop in the following way. Suppose A is the location of the root. B is the location of the one non-root node which is in the radio range of root node(Placed at A) C is the location of the another non-root node which is in the radio range of non-root node(placed at B) but not root(placed at A).
Is it a problem?
