[ns] Using OFDMA with NS2

[DJAZIRI SOUMAYA]

Hello,

I am simulating an Ad-Hoc network on NS2 by implementing a multiple technique of
access which one calls OFDMA (Orthogonal Frequency Division Multiple Access). I
don't know how to start… I made research on the Net but any interesting result.
I wish to have documents, simulations carried out or many codes (scripts).
I need some very for my project. Don't hesitate to send anything without
delaying to me, please. I will be very grateful.

Thank you at all in advance.
Soumaya.

[ns] To introduce OFDMA in NS2

[DJAZIRI SOUMAYA]

Hello,

I try to simulate an Ad-Hoc network on NS2. First of all, I try to introduce a
OFDMA into NS2.

OFDMA (Othogonal Frequency Division Multiple Access) is beging considered as a
Multiuser-OFDM and as a multiple access method.

OFDMA provides multiplexing operation of data streams from multiple users onto
the downlink sub-channels and uplink multiple access by means of uplink
sub-channels.

In OFDMA, both time and/or frequency resources are used to seperate the multiple
user signals. Il allows for partitioning the time and frequency resources into
:

OFDM symbols, s=1,...,S (in time dimension)

OFDM subcarriers, n=1,...N (in frequncy dimension)

Each user is allocated a number of OFDM symbols and subcarriers exclusively.


I don't know how to start ??? I try to find solutions of allocation of different
subcarriers to different user.

Please help me.


Thank you at all in advance.

Soumaya.

[ns] source code WirelessPHY

[DJAZIRI SOUMAYA]

Hello,

I try to implement OFDMA in NS-2. For that, I must have the source code of
WirelessPHY. Where I can recover this source code ???

Please give me an answer.

Cordially
