In cooperative transmission selection of relay is considered to be the crucial factor for reliable transmission where multiple parameters are there for decision making. Again, many existing research works highlighted the problem, but none of them considered the vagueness & uncertainty of the decision makers. Currently, Fuzzy analytic hierarchy process (FAHP) proves to be an advantageous scheme for multiple criteria decision-making (MCDM) in fuzzy conditions. This paper provides FAHP-based relay node selection scheme that prioritizes the fuzziness of the decision makers during the relay node selection procedure. Numerical examples and simulation study, both are carried out to find out the best relay. The simulation study reveals the fact that the proposed scheme outperforms the existing systems.
