A Mobility Improvement Handover Scheme for
This paper presents a mobility improvement handover algorithm with less scan time implementation for Mobile WiMAX. Mobile WiMAX is a wireless technology based on IEEE802.16e for broadband wireless access. Mobile WiMAX introduces the most significant new feature, mobility to support for handovers, which can be considered as a basic requirement for mobile communication system. The mandatory hando...
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 کاملSecured Route Optimization and Micro-mobility with Enhanced Handover Scheme in Mobile IPv6 Networks
خسارات وارد شده به شبکه گاز شهری در یک زلزله میتواند زیانهای زیادی از جمله خسارت ناشی از آتشسوزی در شبکه زیر ساخت، و خسارت ناشی از قطع خدمات رسانی، تعمیر و تعویض اعضای شبکه، را در بر داشته باشد. در این مقاله یک مدل آتشسوزی پیشنهاد شده است. مدل پیشنهادی در یک مدل نیمه احتمالاتی مرسوم برای برآورد خسارتهای مختلف ناشی از آسیب دیدن شبکه گاز شهری، به کار برده شده است. هدف از این کار توسعه یک ابز...
متن کاملA Fast and Simple Scheme for Mobile Station-Controlled Handover in Mobile WiMAX
A Mobile Station (MS)-controlled fast and simple scheme of handover (HO) in Mobile WiMAX network has been described. An MS can roughly estimate its present distance from any neighbouring Base Stations (BS) using the Received Signal Strength (RSS) and an appropriate pathloss formula. From the Mobile Neighbor Advertisement (MOB_NBR-ADV) broadcasts, the MS periodically monitors the RSS of its Serv...
متن کاملA Fast Authentication Scheme for WiMAX-WLAN Vertical Handover
In view that authentication has made a significant determinant in handover delay, this paper presents a fast authentication mechanism for mobile stations roaming within a WiMAX–WLAN interconnected environment. Incorporating a key reuse design that prevents repeated transactions at a remote server, our mechanism distributes security contexts ahead of handover to a local trusted key holder which ...
