============================================================


Q1: Write a networking program consisting of a client and
    server components. The client must request for a file by
    providing a file name, and the server must respond with the
    contents of the file or an appropriate error message.
    Modify the client to accept the filname via a command line
    argument.

============================================================

Q1: Setup an IEEE 802.3 network with 
    a) hub 
    b) switch 
    c) hierarchy of switch
    Apply the FTP, Telnet applications between nodes. Vary
    the number of nodes. Vary the bandwidth, queue size and
    observe the packet drop probability.

Q2. Setup a wireless sensor networks with atleast two device
    co-coordinators and nodes. Provide Constant Bit Rate (CBR),
    Variable Bit Rate (VBR) application between several nodes.
    Increase the number of co-coordinators and nodes in the same
    area and observe the performance at physical and MAC layers.

Q3. Setup an IEEE 802.11 network with at least two access
    points. Apply the CBR, VBR applications between devices
    belonging to same access points and different access points.
    Provide roaming of any device. Vary the number of access
    points and devices. Find out the delay in MAC layer, packet
    drop probability.
