في هذا المشروع سوف نستثمر مجموعظة من الأدوات الرياضية من خوارزميات تعلم الآلة machine learning و الأمثلة المحدبة convex optimization و "النماذج الاحتمالية البيانية" probabilistic graphical model في إطار "الشبكات المعرفية" cognitive networking وذلك لأمثلة optimize أنواع مختلفة من الشبكات اللاسلكية مثل: شبكات الحساسات اللاسلكية WSN ، و الشبكات التكتيكية الهجينة
tactical networks ، و الشبكات المحلية اللاسلكية WLAN . تتمثل "الشبكات المعرفية" في تطبيق "معرفة"
cognition على كامل مكدس البروتوكولات protocol stack لتحقيق أهداف الأداء، بخلاف "الراديو المعرفي"
cognitive radio الذي يطبق المعرفة فقط على الطبقة الفيزيائية.

Compressive Sensing (CS) shows high promise for fully distributed
compression in wireless sensor networks (WSNs). In theory, CS
allows the approximation of the readings from a sensor field with
excellent accuracy, while collecting only a small fra
Wireless Mesh Networks, WMNs, are foreseen to be an alternative to LANs and last- mile access

in all directions without any control of a central manager. This type
