Many applications that consist of streams of data are inherently distributed. Since input stream rates and other system parameters such as the amount of available computing resources can fluctuate significantly, a stream query plan must be able to adapt to these changes. Routing tuples between operators of a distributed stream query plan is used in several data stream management systems as an a...

Networks on chip have evolved as the natural solution for a scalable interconnect that can be automatically generated to suit the needs of the desired application. In this study we focus on improving the efficiency of on-chip networks using alternative routing strategies. We focus on a multi-path slot allocation method in networks with static resource reservations, in particular TDM NoCs. The s...

We discuss the issue of computing resource-optimal routing plans in a network domain. Given a number of known traffic demands, with associated required delays, we discuss how to route them and allocate resources for them at each node so that the demands are satisfied. While a globally optimal routing plan requires joint computation of the paths and of the associated resources (which was claimed...

With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...

We introduce Colored Resource Allocation Games as a new model for selfish routing and wavelength assignment in multifiber all-optical networks. Colored Resource Allocation Games are a generalization of congestion and bottleneck games where players have their strategies in multiple copies (colors). We focus on two main subclasses of these games depending on the player cost: in Colored Congestion...

Achieving efficient bandwidth utilization in ad-hoc networks is known to be a challenging open research issue. Recently, much attention has been devoted to wireless mesh networks and consequently, it has been renewed the interest in improving the performance of ad-hoc networks, which are used as the backhaul structure of hybrid ad-hoc/cellular systems. Moreover, fairly new concepts such as mult...

Femtocells offer many advantages in wireless networks such as improved cell capacity and coverage in indoor areas. As these femtocells can be deployed in an ad-hoc manner by different consumers in the same frequency band, the femtocells can interfere with each other. To fully realize the potential of the femtocells, it is necessary to allocate resources to them in such a way that interference i...
