Yoğunluk-Uyarlı Kablosuz Şebekeler (DAWN)
Yüksek veri iletim ihtiyacı olan uygulamaların sayısı artıkça, mobil haberlesme talebi de artmaktadır. Artan gereksinimi karsılamak için hücrelerin küçültülerek kısıtlı olan kablosuz bant genisliginin verimli kullanılması gerekmektedir. Çok sayıda dinamik küçük hücrenin ortaya çıkmasıyla gezgin aglar da tasarsız sebekelere benzemektedir ve bir paradigma degisimi yasanmaktadır. Küçük hücrelerin rastlantısal sekilde sebekeye dahil olması ve ayrılması, sebeke yogunlugunun önceden kestirilemeyecek sekilde degismesine neden olacaktır. Yogunluk degisimleri ise servis ve tecrübe kalitesini etkileyecek ve yerel kapsama alanı kontrolü, sinyal girisimi kontrolü gibi yeni sorunlara neden olacaktır. NP-Hard eniyileme problem çözümü gerektiren merkezi ve statik yapılandırmalar, sebekenin çok büyük olması nedeniyle uygulanabilir olmayacaktır. Dagıtık özdüzenleme teknikleriyle, yogunluk-uyarlı yıgıt (stack) ve mimari gelistirilmesi gerekecektir. Bu projenin amacı büyük-ölçekli küçük-hücreli özdüzenlemeli sebekeleri yogunluk-uyarlı ve yogunluk-farkında yapmaktır. Yeni sebeke yogunlugu kestirim teknikleri önerilmis ve yogunluk-uyarlı kapsama alanı kontrolü teknikleri gelistirilmistir. Gelistirilen teknikler benzetim deneyleri ile dogrulanmıstır.
