Hi,
I have extracted important nodes from handwritten character. After that I have to connect those nodes by "Neighbouhood analysis." How can I do that? Any ideas or any suggestions??

Not sure what that means. It sounds like you got that phrase from some paper. If so, doesn't the paper describe how to do it?
You could threshold and then call imclose() and then bwmorph(BW, 'skel', inf).

wb = im2bw( imread('untitled.jpg') );
bw = ~wb;
se = strel('disk',4);
joined = imclose(bw, se);
thin = bwmorph(joined, 'thin', inf);
imshow(thin)

The above is the output. You can see that all of the neighbours are joined together, and that the result is one continuous outline for the character, together with a dot for the black spot to the left in the original (you did not say to filter that out.) The nodes have been connected using neighborhood analysis -- imclose() is morphological neighborhood processing that does dilation and then erosion.
