  • Game Theoretic approaches in communication networks: Game theory deals with strategic behavior of decision making agents which compete and cooperate for limited resources. This description of game theory suits very much the situation in modern telecommunication networks where users, routers and servers often cooperate and compete for networking and computing resources. Game theoretic approaches have been applied in resource allocation algorithms in wired networks. We will explore ist applications in wireless networks, and try to formulate an game theoretic approach which may improve the mobility protocols. Ahmet Toker
  • Survey of Proactive QoS Adaptivity Mechanisms for Real-time Traffic: In reactive Quality of Service (QoS) mechanisms, the system first experiences some changes resource or parameter levels and then finds a suitable way to cope with the changes in question. However, the trend now in telecommunications is witnessing increasingly varying dynamics of user requests and requirements, and stronger fluctuations in available network resource levels in the heterogeneous infrastructure we have today. As a consequence, proactive QoS mechanisms are necessary. Proactive mechanisms analyze the pattern in resource change and rely on context awareness in order to take an early adaptation step to cope with the probable upcoming changes. Some steps have already been taken in this direction. The work consists of analyzing existing proactive QoS mechanisms and approaches and identifying their potential, their strengths and their weaknesses or open points for research. Muslim Elkotob
  • QoS Adaptation in Self-aware Networks: The increasing heterogeneity, complexity, and unpredictability in the amount of available network resources as well as in the demands of users and applications necessitate a breakthrough in network design. A new trend known as “self-aware” networks deals with networks able to sense their environment, both local and remote, collect information, evaluate the information in question and produce meaningful information about their own state. Especially in the area of QoS, we anticipate that in the future even more user-oriented networked systems will simultaneously exploit a variety of wired and wireless communication modalities to offer different levels of quality of service (QoS), including reliability and security to users, low economic cost, and performance. A user-oriented network however will not usually have precise information about the infrastructure it is using at any given instant of time, so that its knowledge should be acquired from observations: sensing, monitoring, processing, reasoning. The better the reasoning and observation process, the higher the self-awareness. Adaptation mechanisms automatically gain a better performance value as well as stability degree when conducted in self-aware networks since more information is available in order to decide how to adapt compared to the classical case. The work consists of analyzing and surveying self-aware networks as well as QoS mechanisms for content adaptation in such networks. Muslim Elkotob
