WiMAX technology is an affordable solution for high speed 4G mobile broadband applications. It is a standard for long range wireless networking. Extending coverage is an interesting area of research. In WiMAX, cell coverage can be protracted by deploying Relay Stations (RSs) in which the Mobile Station (MS) routes traffic through intermediate RSs to the Base Station (BS). This paper deals with providing a cooperative relaying based on an Enhanced Relay Selection (ERS) scheme. The ERS scheme not only uses fixed RSs, but also recruits femto BSs (fBSs) as new fixed relays and MSs as mobile relays showing pronounced performance cooperative gains.
