There are two type of Research directions in front of me a) Continue doing
a) Continue doing my previous research. I know the basics and simulation tools as well. I can get papers in good forums as well.
b) Choose a latest and future topic, in which even research issues are not defined. Neither real testbeds available nor good simulation tools. Paper publishing can be tough and PhD can get delayed or redirected in between.
Should I go for a or b?
2. Should I speed up publishing from the very beginning of research or should not worry about publications in beginning?
