An Efficient Anycast Mechanism for 802.15.4-TSCH to Improve QoS in IIoT

Algorithm 2

Route list creation in the proposed method.

1:  Inputs:

     links: List of all links in the topology

     nodes: List of all nodes in topology

2:  Outputs:

     routesList: List of all routes to root, respectively

3:  routesList ← ()

4:  fornode ∈ nodesdo

5:    route ← ()

6:    depth ← getDepth(node)

7:    route.insert(node)

8:    fori ← 1,depthdo

9:      parent ← route(-1)

10:     node ←getParent(parent)

11:     route.insert(node)

12:   end for

13:   routeList.insert(route)

14:  End for

15:  Returnsort(routeList)
