Technology and service convergence is current trend of telecommunication and the
guarantee quality of service (QoS) for each application while retaining the best usage of
resources is an important criterion for a such network. This leads to a QoS-based optimization
process for routing (QoSR) and different aspects with respect to the said are briefly mentioned in
this paper as follows: Basis of QoSR technique (II), Bandvvith-based QoSR problem (III), A
proposed QoSR on MPLS-DiffServ architecture model (IV), Disc...
Bound solitons generated in actively mode-locked lasers enable new forms of pulse pairs and multiple pairs or groups of solitons in
optical transmission or logics. In this paper, we present the generation of stable bound states of multiple solitons in an active
mode-locked ﬁber laser using continuous phase modulation for wideband phase matching. Not only that dual-soliton bound states
but also the triple- and quadruple-soliton pulses can be established. Simulation of the generated solitons are demonstrated. We have also
prove by simulation that experimental relative phase diﬀerence and chirping caused by phase modulation of ...

Abstract We introduce a new iteration method and prove strong convergence the-
orems for ﬁnding a common element of the set of ﬁxed points of a nonexpansive
mapping and the solution set of monotone and Lipschitz-type continuous Ky Fan
inequality. Under certain conditions on parameters, we show that the iteration se-
quences generated by this method converge strongly to the common element in a real
Hilbert space. Some preliminary computational experiences are reported.
In this paper, we suggest a new iteration scheme for finding a common of the solution set of monotone, Lipschitz-type continuous equilibrium problems and the set of fixed points of a nonexpansive mapping. The scheme is based on both hybrid method and extragradient-type method. We obtain a strong convergence theorem for the sequences generated by these processes in a real Hilbert space. Based on this result, we also get some new and interesting results. The results in this paper
generalize, extend, and improve some well-known results in the literature.

In this paper, we introduce an approximation extragradient iteration method for solving bilevel variational inequalities involving two variational
inequalities and we show that these problems can be solved by projection sequences and ﬁxed point techniques. We obtain a strong convergence of three
iteration sequences generated by this method in a real Hilbert space.

Ultra-broadband networks are currently attracting signiﬁcant interests in employing
wireless access and optical ﬁber access to the home and to the building at symbol rate
reaching Gb/s. OFDM is a multicarrier modulation technique and considered to oﬀer
signiﬁcant reduction of the data symbol to be carried per carrier channel, especially in
ultra-high speed optical communications with bit rate reaching 100 Gb/s or even higher.
This paper thus presents a novel and generic OFDM system employing both MATLAB
Simulink and FPGA-based development software platform for simulation as well as hard-
