Aggregate Protocol

protocol

12. AboutAggregation
protocol
● A protocol that allows
computation of average,
minimum and maximum
functions
● Each node holds a
numeric value
● Each node knows its
neighbor’s node values

13. Averagefunction
● Divide the sum of the
current node and
neighbor’s node by 2
● The average is computed
at each node in each
cycle

14. MaximumFunction
● Computes the maximum
value between a node’s
value and its neighbor’s
values

17. ConfigFile

18. MaxObserver

19. Returns the maximum value of the nodes in cycle
Returns the number of occurrences of maximum value

20. FromConsole
Prints the maximum value and
the maximum data counts

21. MinimumFunction
● Computes the minimum
value between a node’s
value and its
neighbour’s values

22. CodesforMin

23. ComputingMin

24. ConfigFile

25. MinObserver

26. Returns the minimum value of the nodes in cycle
Returns the number of occurrences of minimum value

27. FromConsole
Prints the maximum value and
the maximum data counts

29. Whatdoesitdo?

30. Included a print statement in observer file to view
what value is been added to stats

31. Result?
Value at each node was
obtained from the protocol

32. Pros
❏ Platform independent
❏ Composed of cycle
driven and event driven
simulation engines
❏ This allows it to be
scalable(CD) and
dynamic(ED)
❏ High configurability

33. Cons
❏ Poor documentation
❏ Code is difficult to
understand at first
