Using GSPBox, create a 60-node random sensor network and define a signal f on the graph as
where c is a constant and d (i, j) is the distance between nodes
i and j (can be found using Dijkstra’s shortest path algorithm).
(a) Plot the graph.
(b) For c = 0
.05, plot the graph signal in the vertex domain using color coding as well as
bar representation. Compute the GFT coefficients, and plot the signal in the frequency
domain. Comment on the frequency content of the signal.
(c) Plot the graph signals for c = 0.5, c = 1, and c = 2 in the vertex as well as frequency
domains. Comment on the smoothness of graph signals as the value of
c increases.

The getDecision procedure defined in Figure 17.4is provided only by coordinators. Define a new version of getDecision to be provided by participants for use by other participants that need to obtain a decision when the coordinator is unavailable. Assume that any active participant can make a getDecision request to any other active participant. Does this solve the problem of delay during the ‘uncertain’ period? Explain your answer. At what point in the two-phase commit protocol would the coordinator inform the participants of the other participants’ identities (to enable this communication)?

Write a program in a class FlowerCounter that computes the cost of flowers sold at a flower stand. Five kinds of flowers—petunia, pansy, rose, violet, and carnation— are stocked and cost, respectively, 50¢, 75¢, $1.50, 50¢, and 80¢ per flower. Create an array of strings that holds the names of these flowers. Create another array that holds the cost of each corresponding flower. Your program should read the name of a flower and the quantity desired by a customer. Locate the flower in the name array and use that index to find the cost per stem in the cost array. Compute and print the total cost of the sale.
