We propose a novel WDM aware weight function for solving the Routing and Wavelength Assignment (RWA) problem in optical WDM networks taking into consideration factors like number of used wavelengths , availability of free wavelengths and route length jointly under dynamic traffic conditions. The performance of proposed routing strategy is studied in combination with first-fit, and most used wav...

Catering to the evolving bandwidth-on-demand applications requires flexible provisioning architectures that ensure fairness to both high end and low end users of internet. Dynamic classification of network paths into long and short, based on traffic dependent connection holding times and a wavelength allocation from different subsets for these categories is a necessity for implementing energy s...

In recent years, customized buses (CBs), a new form of public travel mode between bus and car, has sprung up in China. Its characteristics include flexible routes, each person having seat point-to-point have attracted travelers who seek high-quality travel, especially car travelers, alleviating traffic congestion at peak periods leading to change urban modes. addition providing modes, an exclus...

We address the control plane architecture of how to provide advance quality of service (QoS) in optical burst switching networks based on dynamic wavelength assignment. Unlike existing QoS guaranteeing scheme, such as buffer-based and offset-time based scheme, our proposed dynamic virtual lambda partitioning (DVLP) scheme does not mandate any buffer or extra offset time, but can achieve better ...

The enormous growth of mobile telephone traffic, along with the limited number of channels available, requires efficient reuse of channels. Channel allocation schemes can be divided into three categories: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Hybrid Channel Allocation (HCA). In HCA, channels are divided into two disjoint sets: one set of channels is assigned to ea...

We consider the load balancing and coverage problem of femtocell networks in indoor environment. We propose a novel framework exploiting the Voronoi diagram with respect to the radio propagation distance. Our initial power assignment scheme achieves maximal indoor coverage with minimized maximum required transmit power, which results in reduced interference. Our approach can adopt any radio pro...
