(Due at the beginning of class on 10/06/08)
This assignment will be graded out of 50 points.
In this assignment, you will get introduced to Glomosim, a basic simulator for wireless networks that is popular within the academic research community. Setup GlomoSim simulator in your own UNIX account or in your own Windows system. You can download Glomosim from here. Here are detailed installation instructions and here is a tutorial.
Set up the following two-node wireless network scenario:
Traffic pattern: CBR
Packet Length: 512B
Data Rate: 1Mbps
Simulation time: 10s
<![endif]>Transmission range: Find out the
transmission ranges corresponding to the 8 settings obtained by varying the
following 3 dimensions:
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. Please submit the following:
<![if !supportLists]>a. <![endif]>A brief description of your simulation procedure. 
<![if !supportLists]>b. <![endif]>Script file of command line output. 
<![if !supportLists]>c. <![endif]>A table, giving the transmission ranges for each of the 8 setting. 
<![if !supportLists]>d. <![endif]>A plot of TX power vs transmission range, for a fixed receive threshold of -81.0dBm, for each of the two propagation-loss models. 
<![if !supportLists]>e. <![endif]>A brief analysis or comparison of different propagation models. 
<![if !supportLists]>2. <![endif]>Performance analysis of different signal coding schemes: Set the following parameters in your config file:
Tx Power: 1dBm
Using BER as the receiving criteria, compare the packet loss ratios under three different coding schemes: BPSK, DPSK, DBPSK. Hint: In the config.in file the following parameters set BPSK as the coding scheme.
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, repeating the above simulations.
