Analysis of ALTO protocol over P2P networks
Kökten, Koray (2012-10)Currently, for distributed applications such as Peer-to-Peer (P2P) and Content Delivery Networks (CDNs), the most important challenge is to determine the optimal peer or node selection process, since it sometimes causes ... -
Application-based scheduling for indoor femtocell networks
Mungan, Devin (2013-01)This thesis is concerned with designing a QoS-enabled, application-based scheduler for indoor femtocell networks. For this purpose, a novel scheduler is proposed which takes into account the quality of service (QoS) ... -
Associative and frequentist opponent modeling approaches in automated bilateral negotiations
This thesis mainly focuses on the problem of learning opponent's preferences during the negotiation in bilateral automated negotiation in which agents negotiate with each other to reach an agreement. Accordingly, it addresses ... -
Cost minimization in function-as-a-service computing
Cost in Function-as-a-Service computing is influenced by a number of factors. One of these factors is the amount of memory reserved during the deployment of serverless functions. Reservation of an excessive amount increases ... -
