KABLOSUZ AĞLARDA KAYNAK YÖNETİMİ

Öz

Bu çalışmada, çokluservis kablosuz ağlarda, servis kalitesi sağlamak için etkili radyo kaynak yönetim tekniklerinden arama izin şemaları incelenmiştir. Yeni nesil kablosuz ağlar (3G, 4G) daha fazla sayıda kullanıcıyı ve multimedya servislerini destekleyecektir. Artan kullanıcı ve multimedya servisi ihtiyacı ile birlikte servis kalitesinden ödün vermeden kısıtlı kaynakları en verimli biçimde kullanabilmek için, etkili radyo kaynak yönetimine gereksinim duyulur, bu gereksinim için farklı arama izin şemaları ve bu şemaların değerlendirilmesinde Markov zinciri modeli incelenmiştir

Resources Management in Wireless Network

Öz

In this study, for providing quality of service, call admission control shemes, one of the most important methods in efficient radio resource management techniques, have been reviewed. Next generation wireless Networks (3G, 4G) will be support more users and multimedia services. With increasing user number and multimedia service needs, for using limited resources in a efficient way, it is needed efficient radio resource management, differrent call admission schemes and evaluation of these schemes with Markov Chain model has been explained for this requirements

Anahtar Kelimeler

• Management, Call Admission Control, Markov Chain
