How to create a pager to display next article in particular taxonomy?
You can accomplish this with the contrib module Flippy. It will allow you to add pagers for specific content types. Hope it helps.


  Flippy is an ultra-simple module that generates previous/next pagers
  for content types. On the Node type administration screen, you can
  turn Flippy on or off for each content type. It'll generate a unique
  pager for each content type, so you can page through Articles or page
  through Blog posts, but you can't page through all nodes on the site.
