1. Write a program to create 2 Nodes, connect them in to duplex-link and attach UDP protocol and CBR traffic for packet transmission.
2. Write a Program for simulation, to create 3 Nodes with duplex link, using TCP protocol and FTP traffic with 1Mbps bandwidth and 10ms delay packets are send from source node to destination node.

4. Write simulation programs for unicast routing and multicast routing using 5 Nodes.
5. Write a simulation program for Local Area Network.
6. Write simulation programs for comparing different routing protocols in WSNs using parameter throughput, delay and PDF.
7. Write a program for simulation to creating 3 Mobile nodes having initial locations of nodes 0,1 and 2 are (5,5), (490,285) and (150,240) respectively, the z co-ordinate is assumed through out to be 0. At time 10 node 0 starts moving towards point (250,250) at a speed of 3 m/sec. At time 15 node 1 starts moving towards point (45,285) at a speed of 5 m/sec. At time 110 node 0 starts moving towards point (480,300) at a speed of 5m/sec. Node 2 is still throughout the simulation. TCP communication is initiated between node 0 and node 1. We used DSDV ad-hoc routing protocol and the IEEE802.11 MAC protocol.
8. Write a program for simulation to create 8 sensor nodes using chain topology, use the standard two-ray ground propagation model, IEEE 802.11 MAC protocol, an omni-directional antenna and AODV routing protocol having interface queue length 100 at each node. Source node 1 sending data to destination node 8 using tested NewReno version of TCP.
9. Write simulation programs for WSNs comparing different MAC protocols having parameters Energy, Latency and PDR.
10. Write a simulation program to check the effect of bottleneck in a wired scenario. Node 1 and node 2 are connected to node 3 via 100 Mbps point-to-point wired link with 1ms propagation delay. Node 3 is connected to node 4 via 10Mbps point-to-point wired link with 1ms propagation delay. Place node in the same order. Node 1 and node 2 are sending CBR traffic to node 4.

11. Write programs for simulation to create 20 WSN nodes in an area of 50m×50m with all nodes being in the transmission range of each other. Each source randomly transmits data in bursts of 3.5 sec at intervals of 20sec. within a burst each node generates one packet per frame, leading to a packet arrival rate of 4.24pkt/sec.

We vary the number of sources from 1 to 10 and calculate the packet delivery ratio. Calculate the Latency. Calculate Average energy per packet and Average energy per node.
12. Write a program for the simulations we consider 150 nodes in 700m×700m the sources are deployed uniformly randomly in the area. Parameter values are same as previous. We vary the average number of sources in the carrier sense range of any node from 1 to 10. Ex-To get an average 5 sources in the carrier sense range of any node we set the total number of sources to 20 calculate PDR, Latency and Avg energy/pkt for each case.
13. Write a program for the simulations, we consider 150 nodes in an area of 700m×700m. As before the nodes are deployed uniformly randomly in the area. We fix the average no. of sources in the carrier sense range of any node to 10 i.e a total of 39 sources selected randomly from the nodes in the simulation area. Each source randomly transmits data in bursts. The duration of these bursts are set to be exponentially distributed. The parameter is same as previous, we vary the mean length of the burst from 1sec to 10sec. The interval between bursts is also exponentially distributed with a mean of 15sec calculate, PDR, Latency and Energy per packet in each case.
