But downloading it using the trick from the post worked too - I used the command d:\wget\wget --referer http://scholar.google.com "http://www.academia.edu/download/52892295/A_Survey_on_Detection_of_Byzantine_and_Resource_Consumption_Attacks.pdf"
And if you want to download from academia, the link academia.edu/download/52892295/… works, but you will have to "pretend" that you come from google scholar, since academia.edu checks the http referer.
That is what I used wget for. They are probably many different ways how to do that.
And the link I used for wget I got from the page you linked.
I followed the advice given in the answer where you commented.
I found in the source of the page doc_id: 52892295 and redirect: "https://www.academia.edu/32733970/A_Survey_on_Detection_of_Byzantine_and_Resource_Consumption_Attacks?auto=download".
I manually changed the url to http://www.academia.edu/download/52892295/A_Survey_on_Detection_of_Byzantine_and_Resource_Consumption_Attacks.pdf.
