Q 2. a) An incomplete VTCSMA-L transmission status table for ? = 2 and transmission time equal to 20 is given below. Find how many calls can be sent and at what time?

Node	RC at arrival	D_M	L_M	RC at Transmission
1	2	28	8
2	10	40	20
3	12	56	36
4	18	68	48
5	24	86	66
6	40	102	82

Q 2. b) Show the working of LDCR and MDCR protocol on the given message set. For nodes N_i (arrival, slots, deadline) :{(4,3,30), (2,2,6), (0,1,2), (3,4,7), (5,4,16), (16,3,23)}

Q 3. a) A set of six tasks with backup copies is to be scheduled by using Myopic algorithm with some distance. Find that distance with which the tasks are feasibly scheduled. Draw schedule also.

Task T_i	r_i	d_i	c_i
T₁	0	20	6
T₂	0	25	8
T₃	4	30	5
T₄	6	40	5
T₅	8	50	4
T₆	8	50	6

b) If the set of tasks given in Q 3 a) is scheduled on three processors using The Backup Overloading Algorithm, how much time do you save?
