A New Adaptive Model for Throughput Enhancement and Optimal Relay Selection in IEEE 802.16j Networks
IEEE 802.16 standard is created to compete with cable access networks. In the beginning end users are immobile and have a line of sight with base station, now it moved to mobile Non Line Of Sight (NLOS) with the new standard IEEE 802.16e and IEEE 802.16j. The new IEEE 802.16j standard which is an amendment to IEEE 802.16e is Mobile Multi hop Relay (MMR) specification for wireless networks. In this paper, the authors have proposed a new adaptive model for transparent mode IEEE 802.16j MMR networks and studied about the throughput enhancement, optimal relay placement and spatial reuse techniques. They have used four Mobile Stations (T-MS) connected to Transparent Mode Base Station (TMR-BS), which are moving at a speed of 20 m/sec.
