Introducing and evaluating a relaying concept for the IEEE 802.16 wireless metropolitan networks

Wireless metropolitan area networks constitute one of the most rapidly evolving research areas. Indicative of the interest this area presents is the newly standardized IEEE 802.16. One of the most interesting, as well as, challenging extentions is to provide relaying capabilities to such networks. In this paper we present such a relaying concept which we believe combines simplicity and efficiency. This model is developed on top of the WiMAX model provided for the NS2 network simulator. Through numerous simulations an evaluation of the NS2 WiMAX model, as well as, the proposed relaying concept is presented considering two different simulation scenarios.
