Hello Maryam,

Is it the below error you are refering to:

??? function oneRoundWSN(numNodes,grid,receiver)

|

Error: Function definitions are not permitted at the prompt or in scripts.

hello Yogesh,

yes, i face to this erro: ??? function oneRoundWSN(numNodes,grid,receiver)

|

Error: Function definitions are not permitted at the prompt or in scripts.

The matlab script is a function. In order to get it to work, you need to pass the variables numNodes, grid and receiver.

numNodes would be the number of nodes if I am not mistaken.

grid would take value 0 or 1 as per the comments in the m-file.

receiver is the ID of the base station. (If I understand properly, it should be a value between 1 and numNodes).

Copy the code in the attached txt file and paste it in an m-file and save it as "oneRoundWSN.m".

In the matlab command prompt try:

>> oneRoundWSN(10, 0, 1)

where,

10 is the number of nodes

0 denotes the grid => random topology

1 is the base station ID I chose between 1 and 10(number of nodes defined).

Thanks,i try and tell to you..

That error is correct but this error come:

Input argument "numNodes" is undefined.

Error in ==> WSN at 16

numNodesXY=round(sqrt(numNodes));

I am try and it work,

Thanks a lot....
