Question
Please implement Flood_ST algorithm follow
Algorithm on our asynchronous thread simulator.
with Python
4.3 Flooding-Based Asynchronous Spanning Tree Construction
Algorithm 4.2 Flood_ST
1: int parent +1
2: set of int childs Ø, others Ø
3: message types probe, ack, reject
4:
5: if i = root then
> root initiates tree construction
6:
send probe to I'(i)
7:
parent i
8: end if
9:
10: while (childs U others) + (T(i)\{parent}) do
receive msg(j)
case msg(j).type of
11:
12:
probe: if parent =1 then
parent j
send ack to j
send probe to I(i)\{j}
else
13:
> probe received first time
14:
15:
16:
17:
> probe received before
send reject to j
childs childs U{j}
reject: others + others U{j}
18:
D include j in children
> include j in unrelated neighbors
19:
ack:
20:
21: end while
