Abstract :
In this paper the model for coloring the edge (channel assignment) and eliminating the secondary interference is introduced. This algorithm is run in the network manager with our routing and scheduling algorithm. One of the constraints in coloring the edge is when we have broadcasting transmission together with the unicast transmission in one time-slot; for this situation several solutions such as changing the coloring algorithm or having a multicast transmission in time, or considering only the unicast transmission which increases the length of frame are proposed. We also have a brief introduction of ISA-SP100 and wireless HART standards.
