0. If you do not have a CCIS Unix account, then please apply for one.
The instructions are on the following page.  I will also get forms
with me to class.

1. Read Glomosim_manual.txt and Glomoman.pdf in the
/course/csg250/Assignments/Simulation/doc directory.  

Copy the /course/csg250/Assignments/Simulation/glomosim/bin to your
home directory.

You can also install Glomosim on your own machine.  See:

http://pcl.cs.ucla.edu/projects/glomosim/

2. Set up the following scenario:

Node number:            2
Terrain:                1000*1000
Traffic pattern:        CBR
Packet Length:          512B
Data Rate:              1Mbps
Simulation time:        10s
Static Routing

3. Transmission range.

Find out the corresponding transmission ranges of 8 settings obtained
by varing the following 3 dimentions:

Tx Power:               1dBm, 10dBm, 
Tx Receive Threshold:   -81.0dBm, -91dBm
PROPAGATION-PATHLOSS    FREE-SPACE,  TWO-RAY

Compare your results with the equations in section 2.3 of
glomoman.pdf.

4. Performance of different coding schemes.

Tx Power: 1dBm
RADIO-RX-SENSITIVITY -100.9
RADIO-RX-THRESHOLD   -100.9

Using BER as the receiving criteria, compare the packet loss ratios
under three different coding schemes: BPSK, DPSK, BDPSK.  (hint: in
the config.in the following parameters sets BPSK as the coding scheme.

RADIO-RX-TYPE           BER-BASED
BER-TABLE-FILE          ./ber_bpsk.in)

Plot the packet loss rate as a function of traffic distance, varying
the distance in step of 10 meters from 250m to 370m.

Change the packet length to 32B, repeat the simulations in question 4.
