    Abstract: Packet Delay and Bandwidth Consideration for Real-time and Non-real-time Applications for QoS Oriented Network Selection in IEEE 802.16e WiMAX Networks The IEEE 802.16 standard WiMAX (Worldwide Interoperability for Microwave Access) network is one of the widely used 4G networks since it provides high-speed data over a wide coverage area. In this, the standard 802.16e supports both fixed and mobile nodes in which the quality of service (QoS) will get degraded due to frequent and false handoffs which should be minimized for getting uninterrupted services. The handoff is a process of disconnecting the mobile device from the old base station and reconnecting it with the new base station. Generally, the handoff will occur during the mobility when the received signal strength goes below the acceptable level. But in the recent scenario, the handoff may be triggered for many reasons such as poor QoS, monetary cost, interference, battery level, etc. In the literature, many handoff schemes are proposed for WiMAX networks but no work considered the parameters such as mobile velocity, ongoing application type, and network status, tolerable uplink packet delay, tolerable downlink packet delay, required uplink bandwidth, and required downlink bandwidth all together. Also, most of the handoff of schemes in the literature are suitable for mobile devices and not suitable for fixed devices. In this invention, we have proposed a handoff method for selecting the best base station in the WiMAX network by considering many parameters such as RSS, the velocity of the mobile, network status, application type, tolerable uplink packet delay, tolerable downlink packet delay, required uplink bandwidth, and required downlink bandwidth. Moreover, based on the ongoing application's type (i.e., real time or non-real-time) the preference will be given to either base station with minimum packet delay or base station with maximum bandwidth for performing a handoff. This proposed method is suitable not only for mobile devices it is also suitable for fixed devices which helps in avoiding the ungainful handoffs and in selecting the best WiMAX base station among the available candidates thereby it helps in improving the quality of service. loosing QOS for No time = f Yes Avoid Unbeneficial Estimatethecnrrent network Handoff and Stayin condition and mobilevelocity the current BS No if the eurret network condition is h ad Scan the near by BSs with require ed QoS and add it in list B No Bf I~i > Do HO w ith any BS in B, Yes with Maximum RSS If Velocity = Vt > e yes Is Real-Time- No Application?
