Hello,
I have a given number of nodes, placed randomly according to uniform distribution in a fixed area of square region.
I have few questions in this scenario.
1. Assuming source at center, in multi hop network, with every node has equal probability of being destination, how can i get...
Hi,
I have a polynomial of the form H(Z)=(1+a*Z^c+Z^b)^10.
Could some one tell me, how to get this in simple polynomial form.
Is there a matlab or C code to get this?
Thanks in advance

Hi everybody,
I have a grid network of 8 nodes and sink at center.
With node assuming transmitter, i got average SINR (for that transmitter, there are possible combinations of other nodes interfering)
with a specific Medium access protocol and BPSK modulation and White gaussian noise.
Now i...
Hi,
I have a square grid network with eight nodes on the square (in corners and centre of sides) and one node at the centre.
Having considered centre node as destination, am trying to get bit error rate with fixed poisson traffic at all nodes and fixed packet size.
Bit errors are found with...
Re: Generate combination of elements in C
Thnx for the reply.
I have a k=3 element vector {1,-1,0}
And have n nodes which can transmit any of the three elements.
I need to generate all 3^n combinations i.e with repetition allowed for the elements.
I got the code in MATLAB as
v = [1 -1 0];
n=8...
Hi,
I have k element vector with elements {1,-1,0}.
I need to generate 3 power k combinations.
How can i generate in matlab?
Can someone suggest me logic to get it?
Expecting reply

I have seen a formula for ber as
BER=Σp{signal energy+(number of interfering nodes*its energy)+gaussian noise<0/interference vector} * p{interference vector}
where p{x/y} is probability of x given y
given that signal energy is the one when source transmits +1.
where p{signal energy+(number of...
So for the second question can i proceed by taking worst case i.e considering every node transmits -1. Then BER will decrease if i reduce the number of interferers. Is this analysis correct?
interference help
hi everyone,
In wireless scenario, say a source starts transmitting data (+1, -1, 0) to receiver and there exists many other nodes which are transmitting ( say +1, -1, 0) and are in the range of receiver.
My query is suppose if the source transmits +1,
1.does the other nodes...
