MPLS (Multi-Protocol Label Switching) over WDM (Wavelength Division Multiplexing) networks are gaining significant attention due to the efficiency in resource utilization that can be achieved by jointly considering the two network layers. This paper addresses the design of MPLS over WDM networks, where some of the WDM nodes may not have packet switching capabilities. Given the WDM network topol...

in this paper, sufficient conditions are proposed to investigate the robust stability of arbitrary switched linear systems with uncertain parameters belongs to the known intervals. in addition, a method is then established to determine the maximum intervals of parameters' variations which guarantee robust exponential stability of uncertain switched linear systems under arbitrary switching. in t...

due to the high efficiency and low switching losses of resonant power convertors in comparison with switching convertors, nowadays there is a growing trend towards these convertors. however, because of the high frequency of switching in such convertors, it is quite difficult to present an efficient control method. in this paper, based on the state feedback method and using pole placement techni...

In this paper, an integration framework for 4Gnetwork architecture between UMTS-GPRS system and 802.11 WLAN systems using MPLS as the underlying technology is developed. In 4G networks, to suffice the needs of users with relatively low mobility but yet to provide a substantial amount of bandwidth in hot-spots, it becomes essential to integrate WLAN 802.11 systems with currently existing UMTS-GP...

Metacognition refers to the use of one's cognitive processes to coordinate behavior. Many higher cognitive functions such as feeling-of-knowing judgment and theory of mind are thought to be metacognitive processes. Although some primate species also show this ability in the form of behavioral control, a rodent model of metacognition is required for advanced studies of this phenomenon at behavio...

The performance evaluation of mobile packet switching networks is nowadays an important topic in mobile communications. In the INTERNET, a classical packet switching environment, a hierarchical approach to the mobility management problem has been followed, focusing mainly on macro-level and micro-level mobility: while MOBILE IP provides a good framework for allowing users to roam between domain...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...
