60 GHz Kablosuz Kişisel Ağlar İçin Esnek Kılavuz İşaret Tasarımı

Bu makalede farklı kılavuz işaret stratejilerinin kablosuz kişisel ağların başarımına olan etkisini incelenmiştir. Ağ koordinatörleri kılavuz işaretleri, ağın varlığını belirtmek için kullanırlar. Eğer kılavuz işaretinin menzili uzunsa, komşu ağlarda bulunan cihazlardan daha az girişim alınır. Fakat bu durum belli bir alanda sınırlı sayıda ağa izin verip ağ başına düşen cihaz sayısını arttırır. Kılavuz işaretinin ağ kapasitesine olan etkisini incelemek için IEEE 802.15.3c tabanlı 60 GHz kişisel ağları seçtik. Uzun haberleşme menzili olan kılavuzlar girişim altında olan cihazlara yaklaşık %20 daha fazla kapasite sağlamakla beraber çok daha az sayıda ağa izin vermektedir. Ayrıca bu çalışmada kablosuz ağın girişimden korunması için esnek bir kılavuz işaret sistemi önerilmiştir. Esnek kılavuz işaretleri hem girişime dayanıklılık sağlarken hem de toplam kablosuz ağ sayısını yüksek tutmaktadır.

Flexible Beacon Design For 60 GHz Wireless Personal Area Networks

In this paper we investigate the effect of different beaconing strategies for wireless personal area networks. Beacons are used by network coordinators to indicate the existence of the networks. A long beacon range protects the devices from interference of neighboring networks. Nevertheless increased protection reduces number of possible networks in an area and increases number of devices per network. We investigate the effect of the beacon range in terms of throughput in IEEE 802.15.3c based 60 GHz WPANs. Long range beacons enable %20 more, while allowing %40 less networks. throughput In addition we are suggesting a flexible beacon system which can adjust the piconet protection. In certain situations, flexible beaconing both increase the troughput of protected link and the total number of networks in the area.
