**4.3. Interfering edges**

To include the interference in network model, we introduce the concept of *Interfering edges.*  Interfering edges for an edge *e* (IE(*e*)) are defined as the set of all edges which are using the same channel as edge *e* but cannot use it simultaneously in active state together with edge *e*. All edges are competing for the same channel hence the goal of channel assignment algorithm is to minimize the number of all edges *e* thereby increasing capacity (Husnain Mansoor Ali et al., 2009).
