Wireless communication systems aim at supporting multimedia services with different Quality of Service (QoS) and bandwidth requirements. Effective management of limited resources is vital to enhance the network performance. Moreover, Mobile WiMAX should meet the expectations of mobile users to provide secured and seamless services. Lengthy delay due to the time-consuming authentication procedures in IEEE 802.16e handover schemes seems to be a bottleneck. It may lead to service disruption when a mobile user moves between Base Stations (BSs).
