متن کاملPerformance Evaluation of Mobile Wimax Ieee 802.16e for Hard Handover
Seamless handover in wireless networks is to guarantee both service continuity and service quality. In WiMAX, providing scalability and quality of service for multimedia services during handover is a main challenge because of high latency and packet loss. In this paper, we created four scenarios using Qualnet 5.2 Network Simulator to analyze the hard handover functionality of WiMAX under differ...
متن کاملA Velocity-Adaptive Handover Scheme for Mobile WiMAX
Mobile WiMAX is a wireless networking system based on the IEEE 802.16e standard. In order to support mobile, some kinds of handover schemes must be adopted, and the hard handover is defined as mandatory. Since the data transmission should be paused during the hard handover process, it causes handover delay in mobile communication. The handover delay makes severe degradation in system performanc...
متن کاملCapacity Evaluation for IEEE 802.16e Mobile WiMAX
We present a simple analytical method for capacity evaluation of IEEE 802.16e Mobile WiMAX networks. Various overheads that impact the capacity are explained and methods to reduce these overheads are also presented. The advantage of a simple model is that the effect of each decision and sensitivity to various parameters can be seen easily. We illustrate the model by estimating the capacity for ...
متن کاملPerformance Analysis of a Mobile WiMAX Network under the Impact of Node Mobility and Handover
In a cellular network, as the mobile devices move from cell to cell during an ongoing continuous communication, handover is performed for switching from one cell frequency to a different cell frequency, without interruption to the ongoing session. Mobile WiMAX handover mechanisms suffer from certain drawbacks, particularly related to wastage of channel resources, handover latencies and loss of ...
